A New Genus and a New Species of Tetrastichinae
from Ghana
(Hymenoptera, Eulophidae)
Miktat Doganlar

Turktichus gen. nov. and its type-species, Turktichus ghananensis sp. nov., are
described and the diagnostic characters of the taxa are illustrated.
Turktichus gen. nov. und die Typusart, Turktichus ghananensis sp. nov., werden
beschrieben. Die diagnostischen Merkmale der Taxa werden illustriert.
In the last two decades the genera of Tetrastichinae were keyed out by several

authors (BOUCEK 1977, 1988; KOSTJUKOV 1978; GRAHAM 1987). BOUCEK (1977) prepared

a tentative key to World genera. KOSTJUKOV (1978) gave a key to the genera of the USSR.
GRAHAM (1987) created a key for the European genera. BOUCEK (1988) gave a tentative
illustrated key to the Australasian genera. But, the keys for African and American genera
are badly needed.
The present paper deals with a study on the specimens of Tetrastichinae from Ghana
in the Zoologische Staassammlung München. By following the key of BOUCEK (1977), the
specimens run to the "? part of Tetrastichus" of the couplet 9 in which Tetrastichodes
ASHMEAD, 1887, was treated as a distinct genus and separated from the group which was

stated as "? part of Tetrastichus", and by following the key of GRAHAM (1987) they run to
the subgenus Tetrastichodes of Aprostocetus WESTWOOD, 1833. But, the specimens from
Ghana differ from Tetrastichodes and represent a new genus in Tetrastichinae, the main
characters of which are given in its diagnosis.
Turktichus gen. nov. (figs. 1-9)
Type-species: Turktichus ghananensis sp. nov. Gender: Masculine.
Body strongly sclerotised, with distinct reticulation, gaster convex, noncollapsed,
sometimes only slightly, retiuculated.
Head (fig. 1) slightly broader than height; frons with median longitudinal line and
transverse suture in front of median ocellus, below it Y-shaped short sutures connected
with median line. Malar sulcus present. Anterior margin of clypeus almost truncate.
Temples nill. Antennal toruli slightly above ventral edge of eyes. Scapus reaching only
ventral edge of median ocellus. Antenna with 2 annelli (fig. 6); funicle with 3 Segments in
female (fig. 6), with 4 in male (fig. 8); fiagellar segments of male with whorls of long setae
which reach about 2/3 of the second segment following that which bears them; clava 3
segmented, the first segment of which with whorls of long setae reaching much fiirther the
tipof clava.
Thorax (fig. 2) with pronotum short. Mid lobe of mesoscutum with median groove
indicatcd in its posterior half, with numerous hairs scattered all over the sclerite.
Scutellum with submedian and sublateral lines and two pairs of setae. Propodeum (fig. 3)
medially broadly and deeply emarginated, at least slightly shorter than dorsellum in
female, less deeply emarginated so as to be slightly longer than dorsellum in male; with
median carina, without plicae, with dense reticulation; spiracles small, subcircular,
separated by about half of their diameter from hind edge of metanotum, whole rim of
spiracles exposed; callus with a sharp carina runs throughout propodeum. Legs moderately
long, with first segment of mid and hind tarsi subequal to second (fig. 4); hind coxae with
raised reticulation, much coarser than that on propodeum. Forewing (fig. 5) with costal cell

shorter than marginal vein, submarginal vein with 3-4 dorsal setae; postmarginal vein
Gastral petiole (fig. 7) very narrow in female, subconical and dorsally finely
reticulated in male (fig. 9). Gaster of female (fig. 7) long ovate, acute apically, longer than
head plus thorax combined. Cerci in a circular cavity surrounded by carina; each cercus
with one seta nearly more than twice the length of the next longest. Ovipositor sheaths
projecting, its exserted portion about postcercale. Gaster of male (fig. 9) narrower, wedge
shaped, broadest near tip, slightly longer than thorax:
Body non-metallic, black, with some pale spots.
Distribution: Ghana.
This genus is distinguished by the combination of the strongly sclerotised, raisedly
reticulated, non-collapsed body, the mesoscutum with numerous setae scattered all over the
sclerite, and with distinct median groove; the scutellum with submedian lines and two
pairs of setae, the fore pair of which located at middle of scutellum; the first segment of
mid and hind tarsi subequal to the second one; propodeum without plicae, callus with a
sharp carina which runs throughout propodeum.


The new genus is similar, in some respects, to Tetrastichodes,
Galeopsomyia GIRAULT, 1916, and Paragaleopsomyia GIRAULT, 1917. It differs from
Tetrastichodes in having the basitarsi of mid and hind legs shorter, and fore pair of
scutellar bristles at about middle of the sclerite (in Tetrastichodes the basitarsi of mid and
hind legs about 1.5 times as long as the second tarsal segment, and scutellar bristles near
hind margin of the sclerite); from Galeopsomyia and Paragaleopsomyia in having the
mesoscutum with numerous setae, and propodeum without plicae (in both genera
mesoscutum with median area bare, and in Galeopsomyia propodeum with plicae mesad of
spiracle; in Paragaleopsomyia propodeum fairly long and submarginal vein with 1-2

Systematic Works on Sigmophora RONDANI, 1867
(Hymenoptera, Eulophidae, Tetrastichinae)
Miktat Doganlar


The main characters of Sigmophora RONDANI, 1867, are obtained in a wide sense
and the known species of the genus are listed. Tetrastichomyia GIRAULT, 1916, syn. nov.
and Koloptema GRAHAM, 1987, syn. nov. are synonymized with Sigmophora. The newly
found male of Sigmophora (= Koloptema) salirta (GRAHAM, 1987) is described and
illustrated. The differences between the specimens from different regions of Sigmophora
brevicomis (PANZER, 1804) are illustrated.
Die Merkmale für Sigmophora RONDANI, 1867, und deren Arten werden festgelegt.
Tetrastichomyia GIRAULT, 1916, syn. nov. und Koloptema GRAHAM, 1987, syn. nov.

werden mit Sigmophora synonymisiert. Das neu gefundene Männchen von Sigmophora (=
Koloptema) salina (GRAHAM, 1987) wird beschrieben und abgebildet. Die Unterschiede
zwischen Exemplaren von Sigmophora brevicomis (PANZER, 1804) aus verschiedenen
Regionen werden abgebildet.
For some time the genus Sigmophora RONDANI, 1867, has been accepted as a
species-group, the brevicornis-group, of Tetrastichus HALIDAY, 1843 (GRAHAM 1961;
DOMENICMNI 1964, 1966; KOSTYUKOV 1978) and as a synonym of Tetrastichus (BOUCEK

GRAHAM (1985) gave it a new Status as a distinct genus, separated it (1987) from the
known genera of Tetrastichinae, gave the main characters of the genus and its synonymy
and prepared a diagnostic key for its European species. BOUCEK (1988) studied the
Australasian species of the genus and gave some synonymy.
KROMBEIN et al. (1978) gave the genus Tetrastichomyia GIRAULT, 1916, as a
synonym of Syntomosphyrum FOERSTER, 1878, which is already a synonym of Aprostocetus
WESTWOOD, 1833. The genus was elevated to generic leyel by GRAHAM (1987), and he
gave its main diagnostic characters in his work.
GRAHAM (1987) described the genus Koloptema, including three new species, and
gave a key for the species.
By the works on the species of the genus Sigmophora in the Zoologische
Staatssammlung München it was found that the species which can be identified under
different genera, viz. Tetrastichomyia. Sigmophora, Koloptema, have many characters
which are almost the same of those given by GRAHAM (1987). In my opinion the genera


Tetrastichomyia and Koloptema are synonyms of Sigmophora. May be, the Australian
genus Aceratoneura GIRAULT & DODD, 1915 can also be united with Sigmophora by the
characters given by BOUCEK (1988).
Sigmophora RONDANI, 1867
Sigmophora RONDANI, 1867: 40. Type-species: Sigmophora scrophulariella RONDANI by
monotypy (GRAHAM 1987).

GRAHAM 1985,1987 and BOUCEK 1988.

GRAHAM (1987) stated that the main characters of Tetrastichomyia were the thorax
with dorsellum divided medially, antenna with third annellus large, with several setae;
scutellum without submedian lines, sublateral lines deep, their outer edge sharply carinate;
vertex with a transverse ridge behind ocellar triangle; mid lobe of mesoscutum without
median line; frons without transverse suture in front of median ocellus. Most of these
characters were also the diagnostic ones for Sigmophora and Koloptema, except divided
dorsellum and large annellus for Sigmophora, in some species of which the third annellus
is still the larger one and with some setae on it (figs. 1 and 694 of GRAHAM 1987). The
main characters of Koloptema, which are given by GRAHAM (1987), are the first segment
of mid and hind tarsi much shorter than the second (fig. 11 and figs. 38, 39, 73 of GRAHAM
1987). But the basi tarsi of mid and hind legs are sometimes also shorter than the second in
Sigmophora (figs. 3,4). In Koloptema malar sulcus with a sublinear fovea below eye, and
in Sigmophora it has a subtriangular fovea (figs. 40, 72 of GRAHAM 1987). The differences
between them is only the shape of the foveae. In my opinion the ratios of marginal vein and
costal cell are not much important in generic laevel. By studying the species in the
Zoologische Staatssammlung it was found that the males of Sigmophora (= Koloptema)
salina (GRAHAM, 1987) (newly found) have also a divided dorsellum, same as
Tetrastichomyia (fig. 13), it is also slightly indicated in the female dorsellum of salina
from Corsica. All of the specimens of salina have the first segment of mid and hind tarsi
much shorter than the second (fig. 11). The species which can be identified as Koloptema
have also the third annellus large, with some setae (fig. 10). On the other hand, male
genitalia are very elongate in all of the species (figs. 2, 14 and figs. 557-560 of GRAHAM


In the new sense the main characters of Sigmophora are given as follows: Vertex
with transverse carina behind lateral ocelli, carina becomes weaker in some species,
sometimes a second one between ocelli; first segment of mid and hind tarsi very slightly to
distinctly shorter thän second segment; dorsellum undivided or with a Channel or a ridge
which separates it into two lobes; scutellum (flg. 13) with a groove along hind margin, and
with submedian lines slightly indicated or indistinct; male genitalia (figs. 2, 14) very
elongate, 8-14 times as long as broad; antenna of female with three annelli, the third of
which at least slightly larger, mostly quadrate and with some setae, than the first two
annelli combined (figs. 1, 10); 3 funicular and 3 claval Segments; antenna of male (fig. 12)
with 2 annelli, 4 funicular and 3 claval Segments, ventral plaque of scape extending at least
half of its length, Segments of flagellum with compact subbasal whorls of long dark setae.
Malar sulcus with a sublinear, oblong or subtriangular fovea below eye (figs. 40, 72 of
GRAHAM 1987); body non-metallic, black or yellow.
Hosts: Diptera, Cecidomyiidae, especially the genus Asphondylia (GRAHAM 1987;
BOUCEK 1988); Lepidoptera (KROMBEFN et al. 1978); ex Salicomia-Nadeki


Distribution: Temperate to tropical regions of Old World (BOUCEK 1988); all
continents of Old World (GRAHAM 1987); North America (KROMBEIN et al. 1978).

GRAHAM (1987) stated that the Status of the species seems to be an agregate. The
study of the specimens from München showed that the shapes of hypopygia (figs. 5-8), of
annelli (fig. 1) and of mid and hind tarsi (figs. 3, 4) are quite different from the figures 73,
671, 694 of GRAHAM (1987) given for brevicornis. The specimens from München may
belong to the species described from Germany, such as brevicornis (PANZER), setiseries
FÖRSTER. In order to solve the problem, a study of the types of the species synonymized
with brevicornis is badly needed.

The species was described from the females by GRAHAM (1987). The differences
between the female specimens from Corsica and the description of the female of GRAHAM
(1987) are not important. In order to indicate the variations of the species, they are given
below: first funicular segment 4 times as long as broad (in the description it is 4.7 - 5
times); Third funicular segment 1.75 times as long as broad (in the description it is 1.9 - 2
times); head slightly broader than mesoscutum (42:37) (in the description head as broad as
mesoscutum); temple 0.2 times as long as length of eye (in the description it is 0.15 times);
pronotum 0.44 - 0.5 times as long as mesoscutum medially (in the description 0.25 times).

The males were reared together with the females and mounted mostly with the females on
same cards by F. BACHMAIER.

Description of male: Length 1.2 - 1.3 mm. Similar to female except as follows:
Antenna (fig. 12) with scape 1.15 times as long as eye length, about thrice as long as
broad, with ventral plaque almost 0.3 length of scapus; pedicellus plus flagellum slightly
more than twice breadth of mesoscutum; pedicellus twice as long as broad, slightly shorter

A New Genus of Tetrastichinae from North America
(Hymenoptera, Eulophidae)
Miktat Doganlar

Kocaagizus gen. nov. is defined and its type-species, K. pirireisi sp. nov., is
described and illustrated.
Kacoaagizus gen. nov. und seine Typusart, K. pirireisi sp. nov., werden beschrieben
und abgebildet.
In the study on Tetrastichinae specimens in Zoologische Staatssammlung, München,
an interesting specimen was found from North America. It has a very broad mouth and
large mandibles with big long falcate outer tooth and two minute and closely placed inner
teeth, which are seen almost equal to the outer one, due to this, the mandibles seem to be
two-toothed. By the shape of mandible it resembles Chaenotetrastichus GRAHAM, 1987,
but it has only two pairs scutellar setae, and submarginal with 4 dorsal setae. The
specimen seems to similar Tetrastichus halidayi (GRAHAM, 1961) in having broad mouth
and large toothed mandible, but it has propodeum without any plicae. It has an interesting
antenna with first armellus 2.5 times as broad as long, the second lamelliform, with 4
funicular Segments, but Fl without sensilla, 0.33 length of F2. By this apparence of the
antenna is similar to the longicomis-gcoup of Aprostocetus, in which the antenna with 4
funicular Segments, but none of the species of Aprostocetus has so broad mouth and large
mandible. Therefore, any of the characters of the specimen mentioned above cannot be
found in the genera given by BOUCEK (1977 and 1988), and the specimen is keyed out by
following the recent keys for the genera of Tetrastichinae created by GRAHAM (1987 and
1991). It represents a distinct new genus and species.
Kocaagizus gen. nov.
(Figs. 1-3)
Gen.: Masculine. The name from Turkish Tcocaagiz' = broad mouth.
Type-species: Kocaagizus pirireisi sp. nov. by present designation
Diagnosis: Body noncollapsed; head (fig. 1) with very broad mouth, 5 times malar
space which is 0.33 length of eye; malar sulcus present, straight; frons with Y-shaped
median longitudinal line, arms of which reaching posterior ocelli; anterior margin of
clypeus distinctly bidentate; mandible (fig. 2) seems to have two equal large teeth, but


inner one has two minute inner teeth, which are closely approximated. Antenna of female
(fig. 3) with two minute annelli, first of which about 2.5 times as broad as long, second
lamelliform; funicle with 4 Segments; Fl without sensüla, about 0.33 length of F2; clava
with 3 Segments. Thorax with pronotum short, with slightly raised reticulation; mid lobe of
mesoscutum with one row of adnotaular setae on each side, with fme but distinct median
line, its surface with fme engraved sculpture; scutellum with distinct lines and two pairs of
setae; propodeum with spiracles larger and nearer to hind margin of metanotum; median
carina slightly indicated; plicae and paraspiracular carina absent; callus with two setae.
Legs long, hind femora 4.6 times as long as broad; first segment of mid and hind tarsi
almost equal to second. Forewing with SM having 4 dorsal setae; PM a short stub. Hind
wings broad, obtuse apically. Petiole distincly transverse, smooth. Gaster as long and as
broad as thorax; cercus with 3 setae in equal length. Ovipositor not reaching tip of last
tergite; tip of hypopygium distinctly beyond middle of gaster.
Male unknown.
Distribution: New York, USA.
Biology unknown.
Comments: The new genus somewhat resembles Chaenotetrastichus in having broad
mouth and larger mandible as seen in fig.2, but it differs from this genus in having
scutellum with two pairs of setae and forewing with SM having 4 dorsal setae, mid lobe of
mesoscutum with distinct median line (in Chaenotetrastichus, scutellum with 5-6 pairs of
setae; SM with 1 dorsal seta, and mid lobe of mesoscutum without median line) (GRAHAM,
1987).The new genus is also similar to Tetrastichus halidayi in having broad mouth and
large toothed mandible, but it differs from the latter in having propodeum without plicae
(in T. halidayi propodeum with distinct Y-shaped plicae), and also to the elongatus-fgoup
of Aprostocetus in having antenna of female with 4 funicular Segments, but it differs from
Aprostocetus in having very diagnostic mouth region (figs. 1, 2).

mesoscutum medially, mid lobe of mesoscutum as broad as long, with fme engraved


reticulation, with 6 adnotaular setae on each sides; scutellum slightly longer than broad,
moderately convex; submedian lines distinctly nearer to sublateral lines than to each other,
enclosed space about twice as long as broad; setae equal, their length slightly less than

A New Species of Tachinobia BOUCEK, 1977, from Africa
(Hymenoptera, Eulophidae, Tetrastichinae)
Miktat Doganlar

Tachinobia zairensis sp. nov. is described from Lübümbashi, Zaire, Africa, and its
diagnostic characters are illustrated.
Tachinobia zairensis sp. nov. wird aus Lübümbashi, Zaire, Africa, beschrieben, und
seine charakteritischen Merkmale werden illustriert.
The genus Tachinobia BOUCEK, 1977 was described with two species, one of which
from south-eastem Asia, the other from South America by BOUCEK (1977). In his study on
the Australasian genera of Tetrastichinae, BOUCEK (1988) gave the diagnostic characters of
Tachinobia and informations on its biology and distribution such as: Region New Guinea
and Solomon Island (1 sp.), northem South America and West Indies, and West Africa
(probably 2 spp.). Up to now there is no more information on the genus.
The present study deals with the specimens from Lübümbashi, Zaire, Africa. They
were sent to the Zoologische Staatssammlung, München, by Mr. F. MALAISSE. The
specimens present a new species which is close to Tachinobia repanda Boucek, 1977.

broader at middle; pedicellus 1.6 times as long as broad; annelli indistinct; first funicular
segment 1.2 times wider and 1.33 times longer than 2nd segment; 3rd segment about as
long as the first, and about 2.2 times as broad as long; clava about as long as pedicellus
plus funicular segments combined, about twice as long as broad, C1 distictly shorter than
half of clava, C2 only slightly shorter than Cl, C3 with a long spine, length of which about
as long as C3. For sensillae see fig.2.
Thorax moderately depressed, sculpture fme as seen in fig.l. Pronotum campanulate,
distinctly shorter than mesoscutum medially, with a row of long bristles near apical
margin, leaving a bare stripe throughout the margin; the width of the stripe only slightly
shorter than length of the bristles; rest of pronotum with fine small bristles (flg. 1). Mid
lobe of mesoscutum about 1.6 times as broad as long, with 3-4 adnotaular setae, posterior
ones the longest; scutellum about 1.56 times as broad as long, without lines, with two pairs
only moderately long bristles, the length of which distincly shorter than the distance
between posterior pair, anterior pair of bristles before middle of sclerite; anterior margin of
scutellum distictly angulated at middle; dorsellum less than half of propodeum medially
(2:5), about 5 times as broad as long. Propodeum about half length of scutellum, fmely
reticulate with a fme but distinct median carina; plicae absent; callus with 3 hairs, with a
longitudinal carina running from just outside of each spiracle to hind comer of propodeum.
Forewing (fig. 3) with pubescence becoming very sparse proximally, speculum ahnost open
below, basal and costal cells bare; forewing 2.06 times as long as broad, marginal cilia
distinctly shorter than stigmal vein; marginal vein with 8-9 long setae on its front edge;
costal cell only slightly longer than marginal vein (9:8); marginal vein 3.2 times as long as
stigmal vein.
Gaster oval, distinctly pointed, slightly longer than thorax but as broad as thorax;
first three terga dorsally bare, except for dark hairs at sides; 4th tergum with a row of hairs
basally, 5th with two rows of hairs basally and apically; cerci with one seta C-shaped
curved and about twice the length of the next longest. Hypopygium (fig.4) reaching
distictly beyond the middle, emarginate at apex; ovipositor sheaths hardly excerted.
Male unknown.
Material examined: 20 females. Holotype female, Zaire: Lübümbashi, Foret du
Shaba, 12.VI.1974, leg. F. MALAISSE (in Zoologische Staatssammlung, München).
Paratypes: 19 females, same data as holotype.
Biology unknown.
Distribution: Zaire, Africa.
Comments: The new species is similar to the other two species of the genus,
Tachinobia repanda and T. gradwelli BOUCEK, 1977. It differs from both of them in having
scutellar bristles shorter (fig.l) (in both species scutellum with very long bristles) (fig.3 of
BOUCEK 1977 and fig. 1221 of BOUCEK 1988), and mid lobe of mesoscutum with only 3-4
adnotaular setae on each side (in both species, mid lobe of mesoscutum with about 6 pairs
of bristles in two rows). T. zairensis sp. nov. also differs from gradwelli in having antenna
with funicular segments transverse and clava with long spine (fig. 2) (in gradwelli antenna
with longer funicular segments and with shorter and curved apical spine of clava) (figs. 22,
23 of BOUCEK 1977). The new species differs from repanda in having antenna with the 2nd
funicular segment larger than the others (in repanda the larger one is the 3rd funicular


segment) (figs.15-17 of BOUCEK 1977) and 2nd segment of clava is only slightly shorter
than thc first segment (in repanda the first segment is longer than half length of clava).

Notes on the Species of Tetrastichus HALIDAY, 1844,
With Descriptions of a New Subgenus and Two New Species
(Hymenoptera, Eulophidae, Tetrastichinae)
Miktat Doganlar

A new subgenus, Hocatetrastichus subgen. nov., of Tetrastichus HALIDAY, 1844,
with its type species Tetrastichus (Hocatetrastichus) zekioezeri sp. nov. from Cameroon,
Africa, and Tetrastichus (Tetrastichus) ahmetcitiri sp. nov. are described and illustrated.
New findings for 12 other species of Tetrastichus from Europe and Turkey are given.
Eine neue Untergattung, Hocatetrastichus subgen. nov., von Tetrastichus HALIDAY,
1844, mit ihrer Typusart, Tetrastichus (Hocatetrastichus) zekioezeri sp. nov., aus Kamerun
und Tetrastichus (Tetrastichus) ahmetcitiri sp. nov. werden beschrieben und abgebildet.
Neue Funde für 12 andere Tetrastichus-Aiten aus Europa und aus der Türkei werden
In the past, the genus Tetrastichus HALIDAY, 1844, was taken as a wide genus and
many other genera of Tetrastichinae were given as its synoyms by several authors

1978; KROMBEIN et al. 1979). By the works of GRAHAM (1987; 1991) and BOUCEK (1977;

1988) the diagnostic characters of the genera of Tetrastichinae were obtained in tentative
keys and the genus Tetrastichus was well understood. Many genera were taken off from its
synonym list and regarded as distinct genera, and many others were synonymized with
TETRASTICHUS by BOUCEK (1988) and GRAHAM (1991).

In this study the specimens from several parts of world in the Zoologische
Staatssammlung München were studied. By the study 14 species were found, viz., 4 of
them from Turkey, 9 species from Europe and one from Cameroon, Africa.
The specimens from Cameroon are distinct by several characters from the known
species of Tetrastichus and represent a new subgenus. The characters of the new subgenus
and of the subgenus Tetrastichus s. str.were given as follows:
Hocatetrastichus subgen. nov.
(Figs. 6-15)
Body noncollabsed; frons with shallow scrobal area (fig. 6), without median
longitudinal carina; malar sulcus straight, not foveate below eye; anterior margin of
