Diagnosis
Small to medium Oscinellinae with head as wide as or slightly wider than scutum in dorsal view, occiput posteriorly convex in dorsal view, eye usually hairy, gena thin always parallel with ventral portion of eye, scutum elongate, with three parallel lines of shallow incised punctures, wing long and slender, broadest in distal half, with reduced alula and anal angle, legs long and slender, abdomen long and narrow, male genitalia with sternite 6 present, in some species epandrium enlarged and cercus elongate.
Description
(Figs 1–4): Chloropidae, Oscinellinae. Head. Frontal triangle glossy or microtomentose, occiput convex; frons with many interfrontal setulae; cephalic setae short, 6–12 reclinate fronto-orbitals with most dorsal seta proclinate; ocellars and postocellars erect, convergent, vertical setae stronger than other cephalic setae, inner vertical setae as long as outer vertical setae, in line with posterior ocelli; ocelli in most species large; eye large, oval, usually densely haired; postgena clearly visible; gena linear, densely pruinose, very pale except for brown ventral margin; vibrissal angle not projecting, vibrissa present but small; face flat, narrow, pruinose, very pale, facial carina short and small; antenna with scape and pedicel short, first flagellomere large, subquadrate; arista sparsely pubescent, aristal setulae usually longer than width of arista at base; proboscis variable from small to geniculate, but never long, palpus short. Scutum. Pronotum elongate and visible in dorsal view, sulcus between postpronotum and scutum deep and well defined; scutum usually glossy, rarely pruinose, with three parallel lines of finely incised punctures (treated as grooves by Ismay (1993)[2]), less distinct in some species, with one anterior and either one (Enderleiniella flavida) or two posterior notopleural setae, one longer outer postalar bristle and one weak inner postalar setae, one postsutural dorsocentral bristle, all dark; postpronotal seta and other scutal setae weak; scutal setulae short, weak, evenly arranged in three distinct rows; in certain species scattered setulae present between and outside the three distinct rows; scutellum flattened, trapezoidal or rectangular dorsally, with two small marginal projections, bearing one strong bristle, lateral marginal scutellar setae present; Thoracic pleurites bare. Wing. Hyaline (a darkened spot in Enderleiniella maculata), long and slender, broadest in distal half, alula and anal angle reduced, cell c normal, second costal sector longer than third; cell r1 normal and long, R2+3 and R4+5 divergent at base, cell br narrow, crossvein r-m near middle of cell dm, crossvein dm-cu fused with M4 in a right angle. Legs. Slender without outstanding setae or spurs; femoral organ present as a row or small patch of three or four sensillae, tibial organ long oval, velvety, with single longitudinal row of setulae along midline. Abdomen. Narrow, cylindrical; syntergites 1+2 elongate; tergites broad; sternites small and narrow; spiracles 3–5 in abdominal membrane ventral to lateral margins of tergites;
Male specific characters
Sternite 6 present; dorsal pregenital sclerite symmetrical, left and right spiracles 6 and 7 within sclerite close to lateral margin; epandrium variable from small and simple to enlarged and inflated. Surstylus simple, straight, elongate; hypandrium open posteriorly; pregonite and postgonite simple, round and elongate; cercus variable from simple and elongate to multiple lobed; subepandrial sclerite usually small.
Female specific characters
Terminalia unmodified, typical of Oscinellinae.
Comments
The type species, Enderleiniella longiventris, is atypical in having a densely pruinose scutum and a long, rectangular scutellum.
