description: <i>Pennaticoxita tauricornuta</i> Jiao &amp; Bu, sp. nov. Diagnosis. The species is different from other species of the tribe Brachineurini by the aedeagus dorsally with a pair of horn-shaped prominences on the sub-apex, and each prominence approximately as long as gonostylus. Description. Adult. Body colour yellow brown, length 1.00– 1.10 mm (<i>n</i> = 6). Wing length (measured from the base) 1.40–1.50 mm (<i>n</i> = 6), width 0.50–0.60 mm (<i>n</i> = 6). Head (Figs 1–2). Eye bridge 8 facets long in the middle of vertex. Palpus sparsely setose, with palpiger and 3 segments, last two segments longer than first one (Fig. 1). Antenna with 10 flagellomeres; pedicel subglobular, smaller than scape, both densely covered with setae ventrally; node of all flagellomeres subcylindrical, a little broadened subbasally, neck of all flagellomeres a little shorter; each node with 2 horizontal, appressed, band-shaped circumfila, subapically and subbasally respectively linked by two similar longitudinal circumfila, and 2 whorls of long, strong and irregular setae, one subbasal and one subapical; first and second flagellomeres fused; third male flagellomere (Fig. 2) with the node 1.30–1.40 times as long as wide and the neck 4.10–4.20 times as long as wide, 0.90–0.95 times length of node. Thorax (Figs 3–4). Wing (Fig. 3) hyaline, 2.45–2.50 times as long as wide. Vein Sc weak, C, R 1 and R 5 strong; vein R 1 joining vein C at basal 2/5, with one pore near the distal; vein R 5 bent a little backward, joining vein C at wing apex, with one pore at basal 1/3; vein Cu not forked and bent backward, vein CuP parallel with Cu. Legs densely covered with narrow scales and sparse setae. Tarsal claw (Fig. 4) toothed on all legs; empodium shorter than tarsal claw; pulvillus cylindrical. Abdomen. Each tergite and sternite densely covered uniformly with scales. First through sixth tergites developed and strip-shaped, with an irregular but mostly single, posterior row of setae, with several pairs of lateral setae, and with one anterior of trichoid sensilla; first tergite much shorter than second tergite; seventh and eighth tergites both reduced to one strongly sclerotized, latitudinal and linear band with several scattered setae; second through eighth sternites covered with many scattered lateral and central setae, with one anterior pair of closely set trichoid sensilla; second sternite divided latitudinally into two bands, respectively with one single, anterior row of setae and one single, posterior row of setae; third through seventh sternites sub-rectangular with an irregular but mostly single, posterior row of setae; seventh sternite shorter than sixth; eighth sternite crescent, much shorter and much narrower than seventh. Male genitalia (Figs 5–6). Gonocoxite much slender, having a wing-shaped dorsal lobe approximately as long as 3/4 length of gonocoxite, and having mediobasal lobes undeveloped, only with four closely set setae, all inserted in a sub-frustoconical prominence; gonostylus slender, gradually tapered from base to apex, approximately as long as 3/5 length of gonocoxite, covered with a few setae and dense microtrichiae, with a short setae located apically on the inner side, toothed apically; cerci separated deeply and widely with a U-shaped depression forming two broad, semicircular lobes with a few long lateral setae; hypoproct a little longer than cerci, emarginated widely with a U-shaped depression forming two digitiform lobes; aedeagus sub-conical, approximately half the length of gonocoxite, dorsally with a pair of horn-shaped prominences on the sub-apex, each prominence approximately as long as gonostylus and covered with long setae. Female genitalia. Unknown. Holotype &amp;male;. China, Guangxi, Shangsi, Nanping, Milü (21.55°N, 107.43°E; elev. 770 m), 3–5.IV.2002, leg. Huaijun Xue, Malaise trap (NKUCecid. No. BCA001).
