Description.
Female
(holotype). Body length 4.5 mm. Fore wing length 3.35 mm.
Head
very strongly rounded behind eyes in dorsal view (
Fig. 33
); temple short, almost 0.6 times as long as eye width. Inner eye orbits weakly but distinctly convergent dorsally (
Fig. 32
). Mandible with upper tooth distinctly longer than lower tooth. Clypeus probably abnormal, with lower margin abruptly bent backwards (
Fig. 32
); distinctly and sparsely punctate on finely granulate and dull background. Malar space 0.85 times as long as basal width of mandible. Flagellum of antenna filiform, with 18 segments (
Fig. 31
); subbasal flagellomeres about 1.5 times as long as broad,
subapical
flagellomeres slightly elongate; flagellomeres 3 to 7 with distinct subapical finger-shaped structures on outer surface (
Fig. 34
). Face, frons, vertex, and temple distinctly granulate, dull, and impunctate. Mesosoma entirely granulate, dull, and mostly impunctate; mesoscutum laterally with indistinct punctures. Notaulus absent. Foveate groove situated in anterior half of mesopleuron, not reaching prepectal carina anteriorly, almost straight, narrow, slightly oblique, with transverse wrinkles ventrally (
Fig. 31
). Propodeum with basal keel (and few fine subparallel wrinkles), which is 0.37 times as long as apical area (
Fig. 38
). Propodeal spiracle separated from pleural carina by 1.75 times diameter of spiracle. Apical area flat, anteriorly widely rounded (
Fig. 38
). Apical longitudinal carinae distinct only posteriorly, anteriorly absent. Fore wing (
Fig. 35
) with intercubitus thick, shorter than abscissa of cubitus between intercubitus and second recurrent vein. First abscissa of radius almost as long as width of pterostigma. Metacarpus ending far from apex of fore wing. Postnervulus intercepted somewhat below middle. Hind wing with nervellus vertical. Metasoma: first tergite 2.5 times as long as broad posteriorly (
Fig. 40
), with petiole trapeziform in cross-section, well separated from postpetiole in dorsal view, mostly smooth dorsally and laterally, finely striate laterally before glymma, and with postpetiole striate dorsally. Glymma deep, situated at center of first tergite, joining by distinct furrow to ventral part of postpetiole (
Fig. 39
). Second tergite as long as anteriorly broad (
Fig. 40
). Thyridial depression short, transverse (
Fig. 40
). Ovipositor short, weakly upcurved, with moderately deep and sharp dorsal subapical notch (
Fig. 37
); sheath about as long as first tergite (
Fig. 36
).

Head, mesosoma, and first tergite black; palpi and lower margin of clypeus yellowish brown; mandible yellowish brown, blackish basally and with black teeth; tegula yellow. Antenna brown. Pterostigma brown. Legs brownish yellow, hind coxa brownish. Metasoma behind first tergite brownish yellow (
Fig. 36
), tergites 3 to 5 dorsally with brown anterior marks.
Male
. Unknown.
Comparison.
Differs from other Palaearctic species of
Tersilochus
by the combination of conspicuously enlarged eyes (temple short) (
Figs 32
,
33
), short ovipositor (
Fig. 36
) and light brownish yellow metasoma behind first tergite (
Fig. 36
).
