Torymus pastinacae

Torymus pastinacae Graham & Gijswijt, 1998.

Morphology.- Head in dorsal view about twice as broad as long, temples 0.25-0.32 apparent length of eyes, strongly converging and curved. POL 2.25 OOL, OOL 1.15 OD. Vertex finely reticulate, with several, rather indistinct punctures. In frontal view the eyes are separated by slightly less their length. Mouth 2.0-2.2 malar space, the latter 0.35 length of eye. Genae straight. Clypeus slightly curved forwards. Antennae with toruli well above lower eyeline, but slightly nearer to clypeus than to anterior ocellus; scape 4.5 times as long as broad, barely reaching anterior ocellus; pedicellus plus flagellum 1.2-1.3 times as long as breadth of head, flagellum proximally stouter than pedicellus, rather weakly clavate; pedicellus 1.5 times as long as broad; anellus moderately transverse; F1 1.25 times as long as broad, F2-F6 subquadrate, F7 slightly transverse; clava 1.8 times as long as broad; sensilla numerous, uniseriate.
Mesosoma 1.75-1.8 times as long as broad. Mesoscutum 1.4 times as broad as long, with fine reticulation (more rippled-scaly in front); punctures numerous and minute, separated by about twice their diameter; setae rather short, only slightly raised. Scutellum 1.23 times as long as broad, sculptured as mesoscutum; setae on posterior third long and distinctly raised, punctures a little larger than on mesoscutum; flange very narrow, moderately trabeculate. Dorsellum nearly smooth, with a trace of a median sulcus. Propodeum shiny, delicately alutaceous, smoother medially, with a row of very small fovea. Mesepimeron 1.4 times as long as broad, distinctly shorter than mid coxa. Hind leg with coxa 2.4 times as long as broad, sparsely pilose; femur 4.3 times as long as broad, longer spur of tibia 0.46 length of basitarsus. Forewing 2.55 times as long as broad; costal cell about 10 times as long as broad, above with a row of setae in distal third or half plus a few at base, below with one row of setae plus scattered setae at base and distal third; M:PM:ST=71:15:6, stigma very small, petiolate, not at acute angle with PM; basal cell with a few setae below SM, partly closed (distally) or wholly; basal vein with 3-5 setae; speculum moderately large, extending somewhat beyond parastigma, partly open.
Metasoma slightly compressed; basal sternite projecting slightly beyond coxa; hypopygium reaching three quarters along gaster, bare except tip. Ovipositor index 1.9-2.1, sheaths about as long as metasoma plus one third mesosoma. Length 2.4-2.6 mm.
Colour.- As curtisi, but legs tending to be paler: hind tibiae less strongly darkened, usually more or less infuscate but not black, occasionally yellow; fore and mid femora yellow, or darkened beneath, occasionally infuscate in basal two-fifth; fore coxa sometimes partly yellow.
Morphology: eyes distinctly hairy; scape 2.7 times as long as broad, pedicellus plus flagellum 1.4 times breadth of head, segments quadrate to slightly transverse, only F1 longer than broad and narrower than pedicellus and F2.
Colour: scape dark green, legs with all coxae and hind femora green, other parts of legs dark brown except tarsal segments 1-3, which are testaceous.
Biology.- Reared from Kiefferia pimpinellae (Löw) (Dipt. Cecidomyiidae) on Pastinaca and on Peucedanum.
Distribution.- Germany, Yugoslavia.
