Papp, L.: Two new genera of the Oriental Sphaeroceridae (Diptera)
Description - Measurements in mm: body length 1.65 (holotype), 1.55-1.65 (paratypes), wing length 1.38 (holotype), 1.34-1.38 (paratypes), wing width 0.67 (holotype), 0.59-0.65 (paratypes). Body longish, length of abdomen equals that of head and thorax combined. Facial plate slighty convex. Frontal vitta divided, bicolored but both parts densely dashed. Orbitalia less densely dashed. Two pairs of equally long and thick fronto-orbital setae (Fig. 1), plus a number of short orbital setulae. Ocelli rather small. Ocellar triangle not separated, area between ocelli not dashed but microtomentose. Ocellar setae long (0.42 mm) and emerge far from each other. Interocellar setulae short. A pair of extremely long postocellars just on border of vertex and occiput. Inner and outer verticals rather long, occipitals weak. No inner orbitals. Six pairs of medium long ifr. First flagellomere rounded, about as long as broad. Arista (Fig. 1 ) with sparse cilia, the longest 0.025-0.027 mm, cilia on flagellomere shorter. Eye facettes large. Gena broad and strongly broadening posteriorad (Fig. 2), with a medial dashed area (anteriorly running along eye). Genal seta 0.06 mm long on a paratype (Fig. 2). Vibrissa normal, peristomial setae rather weak. Clypeus narrow. Mesonotal setae: 1 postpronotal, 2 notopleural, 1 supra-alar, 2 dorsocentral (anterior one at level of posterior np), 1 thin postalar, 1 postsutural and 1 posterior intra-alar pairs. Acrostichals sparse and not ordered, ca. 4 in the level of sa, ca. 6 in a level anteriorly. Scutellum broad and short, i.e. 0.132 mm long, 0.31 mm broad basally, apical scutellar 0.23 mm, lateral scutellar 0.165 mm long . One medium-long katepisternal seta Wings without long or particularly dense costal setae, basally with 2 setae, the longer one is only 0.062 mm. Radial veins R, and R 2+3 short, latter almost straight, upcurving into costa on a short section only (Fig. 3). Second costal section 0.323 mm, third section 0.385 mm, ratio 0.84. Costal vein definitely overruns apex of R 4+5 .Vein R 4+5 slightly bent towards the costa, i.e. apical part more curved than basal part. Discal cell medium-long, intra-crossvein section of medial vein 0.18 mm, dM-Cu 0.08 mm, ratio 2.25. Medial vein continued as a vein "shadow" almost to wing margin. Cubital vein continued distally to dM-Cu on a short section only. Anal vein rather long, almopst straight. Alula comparatively large and broad, with widely rounded apex. Fore leg without any special setae. Fore basitarsus 0.088 mm. No middle ventral seta on mid tibia. Mid basitarsus 0.22 mm long, no characteristic ventral seta anywhere on it. Mid tibial armature: 0.06 mm long (this is the longest seta on tibia) dorsal at 15/17, anterodorsals at 6/17 and 13/17. Male mid tibia ventrally without long setae or hairs. Ventroapical seta (plus an anteral apical seta) normal. Hind tibia with 3 apical thorns (Fig. 4), the ventral one is the longest. The relative length of the thorns is different from specimen to specimen, in cases only 2 thorns present. Hind basitarsus and second tarsomere enlarged. Claws normal but pulvilli minute (hardly discernible). Tergite 1+2 short (Fig. 5) with comparatively long thin marginal setae. Male tergites 3-5 slightly reduced. Abdominal sterna broad: sternite 4 and 5 almost as broad as abdomen, sternite 2 narrow (small), size of sternite 3 between them. Sternite 5 with a separate caudal sclerite, which bears comparatively long dense setae apically (Figs 6-7). Epandrium and genitalia very small, epandrium with thin and medium-long setae only. Cerci normal. Surstylus (Fig. 8) longer than deep, medially and subapically with a long and thick but not acute thorn, lateral surface with numerous long setae. Postgonite (Fig. 10) with blunt apex, not strongly curved, without remarkable setae. A rather long epiphallus present. Aedeagal apodeme comparatively short. Distiphallus not markedly separated from basiphallus, with a pair of long narrow dorsal processes (Fig. 9). Female unknown. Distribution - Sri Lanka.
