Other characters

Male

BODY LENGTH. 2.0‒ 2.2 mm.

HEAD. Frons glabrous. Eye bridge dorsally 1‒2 ommatidia long. Antenna markedly shorter than body; scape and pedicel concolorous with flagellum; circumfila including posterior extensions present on flagellomeres 1‒11, partly evenly ring-shaped, partly meandering; fourth flagellomere with neck and node equally long ( Fig. 32C ). Palpus as long as head height, 4-segmented, apical segment longest of all.

THORAX. Scutal setae in two lateral and two dorsocentral stripes; setae-bearing stripes clearly brighter than interjacent portions. Presutural windows conspicuously bright, sharply delineated. Pronotum glabrous. Anepisternal setae 4‒5. Anepimeral setae 6.

WING ( Fig. 32B ). Slightly longer than body. Length /width ratio 2.3. M 1+2 missing. M 4 short, separated from CuA, weakly pigmented, multiply interrupted, nearly straight. CuA strongly bent on apical half, nearly extending to wing margin. CuP long, reaching to bend of CuA.

LEGS. Foreleg with femur and tibia equally long, tibia 1.2 × as long as T 2. Claws toothless, slightly bent on apical half. Empodia thin, as long as claws or almost so.

ABDOMEN. First to seventh tergites entire, somewhat tattered laterally, with large, unevenly dispersed setae; eighth tergum either unsclerotized and glabrous, or with vestigial sclerotization anterolaterally. Each of first to eighth sternites consisting of two transverse strips with large setae. Pleural membrane with a few unevenly dispersed sclerotized spots bearing setae.

TERMINALIA ( Fig. 32A ). Ninth tergum membranous and glabrous. Gonocoxal synsclerite broader than long; ventral portions broadly horseshoe-shaped, densely setose; dorsal apodemes unusually short and broad. Gonostylus 2.5× as long as thick, thickest near midlength, tapered towards apex; apical tooth small, fingernail-shaped. Aedeagal apodeme almost as long as gonocoxae, strongly sclerotized; ducts of accessory glands unusually distinct, enter apodeme on apical third. Tegmen elongate, 3× as long as broad, slightly narrowed towards apex, the latter strongly bent dorsad (↓ 3).
