Torymus rosariae Graham & Gijswijt, 1998.
Morphology.- Head dorsally 1.9-2.2 times broader than long, temple 0.25-0.3 apparent length of eye, moderately convex, distinctly rounded; POL 1.9-2.0 OOL, OOL 1.25 OD; vertex with a number of very small punctures. Frontally seen the mouth is 2.2 malar space, malar space 0.34 length of eye; genae slightly curved; front edge of clypeus truncate, or very shallowly emarginate.
Antenna: scape not reaching middle ocellus; pedicellus+flagellum 1.3 times breadth of head; flagellum proximally slightly broader than pedicellus, weakly clavate; pedicellus xx times longer than broad; anellus about 1.7 times broader than long; F1 as long as or slightly shorter than pedicellus, F2 and F3 slightly elongate or quadrate, following segments quadrate, F7 very slightly transverse. (in small females all funicle segments are quadrate except F7, which is very slightly transverse); clava twice as long as broad; sensilla numerous, uniseriate.
Mesosoma twice as long as broad; Mesoscutum 1.3 times as broad as long with fine reticulation, but tending to form transverse ripples in anterior third, punctures very numerous but minute, setae rather short, only very slightly raised; scutellum 1.2 times longer than broad, with subtruncate base, sculptured as mesoscutum, setae slightly raised, those of posterior third long, flange very narrow, not distinctly trabeculate or with very fine trabeculae. Dorsellum nearly smooth. Propodeum with delicate superficial alutaceous sculpture, smoother medially.
Hind leg with coxa 2.3 times longer than broad, , pilose in basal half dorsally; femur 3.6-3.8 times as long as broad, spur of tibia 0.5 length of basitarsus.
Forewing 2.5 times longer than broad; M:PM:ST=64:17:7; basal cell with a few hairs below subcosta, closed distally; basal vein with 3-5 hairs; speculum not broad, extending slightly beyond parastigma, partly open. ST shortly petiolate, small.
Metasoma slightly compressed; basal sternite slightly longer than hind coxa; hypopygium extending 0.75 length of metasoma, bare, except tip. Ovipositor index 1.7-2.1
Body length 2.3-3.5 mm.
Colour: body bright blue-green to blue; mesepimeron wholly brassy or bronze; scape black, yellow beneath. Coxae, usually basal two-third of fore and mid femora, as body rest of legs yellow, with hind tibiae weakly to strongly and broadly infuscate, fifth tarsal segment fuscous. Tegulae yellow. Wings hyaline, venation yellowish.
