Description of female.-
Morphology: head in dorsal view (fig. 174) 2.1 times as broad as long; temples 0.16-0.18 apparent length of eyes, very strongly converging and slightly curved. POL 2.2 times OOL, OOL 1.05 times OD. Vertex finely alutaceous, with several minute punctures. Frontally seen the eyes are separated 0.9 times their length. Mouth 1.86 times malar space, the latter 0.32-0.37 length of eye; genae straight. Antennae (fig. 175) with toruli well above lower eyeline but very slightly nearer to clypeus than to anterior ocellus; scape four times as long as broad, reaching middle of anterior ocellus, virtually as long as transverse diameter of eye; pedicellus plus flagellum about 1.3 times as long as breadth of head, flagellum proximally slightly stouter than pedicellus; funicle filiform, only clava broader than rest of flagellum; anellus 1.3-1.5 times as broad as long; pedicellus 1.8-1.9 times as long as broad; F1 slightly shorter than pedicellus, following segments slightly elongate or quadrate, F5-F7 quadrate; sensilla numerous uniseriate.
Mesosoma 1.75-1.9 times as long as broad. Mesoscutum 1.25 times as broad as long, with numerous very small punctures, at least twice their diameter apart; setae of normal length, slightly raised, sculpture in frontal half more or less rippled. Scutellum 1.3 times as long as broad, punctures as on mesoscutum, setae on posterior third longer, base rounded; flange very narrow, finely trabeculate. Dorsellum smooth with a trace of a sulcus. Propodeum smooth with a row of small fovea basally. Mesepimeron 1.35 times as high as broad, distinctly shorter than mid coxa. Hind leg with coxa 2.2-2.3 times as long as broad with hind edge moderately to strongly curved, thickly pilose in basal half, rather coarsely reticulate, the reticulation in basal two-third slightly raised, femur 3.6-3.75 times as long as broad, spur of tibia 0.45 length of basitarsus. Forewing 2.5 times as long as broad; costal cell nine times as long as broad, with one row of setae in upper surface in distal half, and one row plus scattered setae except in the middle on lower surface; basal vein with four to seven setae; speculum mainly open, extending beyond parastigma; M:PM:ST=67:15:6.5, stigma nearly sessile, oblique, small.
Gaster slightly compressed, basal sternite projecting by about one-quarter beyond hind coxa; hypopygium extending slightly beyond three-quarters of gaster, bare. Ovipositor index 1.5-1.66, as long as gaster or slightly longer. Length 2.1-2.6 mm.
Colour: body bright green to blue-green. Palpi testaceous or brownish. Antennae black, scape testaceous beneath. Coxae, hind femora except bases and tips, as body; fore and mid femora fuscous ventrally; hind tibiae broadly to mainly black; tarsal segment 5 fuscous, 4 brownish. Tegulae testaceous, more or less infuscate posteriorly. Wings hyaline, venation testaceous.
Male.- Unknown.
Comments.- The female of problematicus spec. nov. closely resembles that of galii Boheman, which differs in having mouth slightly broader (2.1-2.15 times malar space) and malar space slightly shorter (0.28-0.3 times length of eye), the antennal scape not or just reaching lower edge of anterior ocellus, its length somewhat less than transverse diameter of eye; pedicellus plus flagellum 1.07-1.25 breadth of head, flagellum thickening slightly distad, F7, F6 and sometimes F5 very slightly transverse, mesosoma 1.55-1.8 times as long as broad. T. galii also tends to be smaller in size.
