Torymus arcella Graham & Gijswijt 1998.
Morphology.- Head in dorsal view 2.15 times as broad as long, temples 0.18 length of eye, moderately convex, very slightly curved. POL 1.8-2.2 times OOL, OOL 1.3-1.4 OD. Vertex finely reticulate with several very small punctures. In frontal view face fairly thickly set with rather short, white setae. Mouth about twice as long as malar space, the latter 0.3 times length of eye; genae straight. Clypeus slightly produced, curved. Antennal toruli distinctly above lower eyeline, but slightly nearer to clypeus than to anterior ocellus; scape nearly reaching ocellus; pedicellus plus flagellum 1.2 times as long as breadth of head, funicle proximally slightly stouter than pedicellus, slightly clavate; pedicellus nearly twice as long as broad; anellus 1.4 times as broad as long; all funicle segments quadrate except sometimes F7 which is may be slightly transverse; clava twice as long as broad; sensilla numerous, uniseriate.
Mesosoma 1.7 times as long as broad, strongly arched, notauli not deep. Mesoscutum 1.3 times as broad as long, finely reticulate slightly rippled in front; setae numerous but rather short; punctures numerous, minute. Scutellum about 1.2 times as long as broad, nearly truncate to rounded at base, punctures as on mesoscutum; setae on hinder third longer than on frontal part; flange narrow but distinctly trabeculate; in the holotype its posterior margin has a row of long, backward pointing setae. Dorsellum nearly smooth or weakly alutaceous. Propodeum very finely superficial alutaceous, smoother medially. Hind coxa 2.2 times as long as broad, hairy dorsally with a double row of setae. Spur of hind tibia 0.4 times length of basitarsus. Forewing 2.3 times as long as broad; costal cell bare on upper side, except in distal third for one row, underside with one, medially widely broken row, plus some scattered hairs basally and in distal half; basal vein with 2-4 hairs; basal cell nearly bare, closed; speculum mainly open, extending to slightly beyond parastigma. M:PM:ST=57:14:5; stigma nearly sessile, very small, circular.
Metasoma moderately compressed; basal sternite reaching only slightly beyond hind coxa; hypopygium reaching nearly level of apex of metasoma, bare. Ovipositor sheaths about as long as metasoma plus mesosoma, index 3.0-3.3. Length 2.0-2.4 mm.
Colour: head and thorax bright green with some golden reflections. Toruli testaceous, scape yellow, pedicellus dark brown, flagellum slightly lighter brown. Palpi and tegulae yellow. Hind coxae and part of the mid coxae coloured as body, rest of the legs yellow, except last tarsal segments, which are brown. Metasoma blue to violet. Wing veins testaceous.
