Diagnosis. See diagnosis for species group.
Description. Male. Body length 8.5 mm, wing length 7.0 mm.
Head mostly subshiny blackish-brown with very thin gray pollinosity. Frontal vitta brown with yellow apex, densely microsetulose, about 1/2 width of frons; lower orbital plate dull pollinose; ocellar triangle black; lunule orange; face pale yellow, densely microsetulose; gena light brown, lightly pollinose; clypeus uniformly brown, shiny and bare, except posterolateral portions of clypeus covered with fine white setulae. Setae and setulae on head black; postgena with 1 strong seta at lower margin. Antenna brownish-yellow; first flagellomere 1.2X as long as broad; pedicel without any long, strong ventral apical seta; arista nearly 3.0X length of first flagellomere, brown except base yellow, bare. Proboscis brown with blackish apex, setulae brown to black. Palpus brownish-yellow, setulae black.
Thorax mostly reddish-brown, notum darker, proepisternum, proepimeron anteroventrally, and antepisternum centrally blackish-brown; lightly pollinose. Scutellum slightly convex, angled dorsally. Setae on thorax black, setulae blackish; katepisternum with 3 strong setae.
Legs mostly dark yellow, except hind coxae brown, apical 1/4 of fore femur black, apical 1/5 of mid and hind femora brown; fore tibia black with apical 1/5 yellow, mid and hind tibiae yellow to brown with base darker; tarsi yellow to brown with apex darker.
Wing dark brown with distal and discal bands dark brown; distal band basal to middle of distal section of M1; discal band along M1 but posterior to R4+5, basal to middle of penultimate section of M1. Bm-cu proximal to CuA2; A1+CuA2 2.3X as long as CuA2; distance between apex of R2+3 and R4+5 0.5X as long as M1 beyond dm-cu ( Fig. 6 View FIGURE 6 C). Halter pale yellow with blackish-brown base.
Abdomen blackish-brown, lightly pollinose. Pleural colour not visible on available material. Epandrium brownish-yellow posteriorly, shiny dorsally, miscrosetulose laterally. Genital fork relatively large and broadly arched, with long black ventral setae; arm large, basal tubercles weak, not contiguous, medial tubercle absent ( Fig. 6 View FIGURE 6 D). Ejaculatory apodeme of sperm pump relatively small, shaped like a ginkgo leaf. Distiphallus as long as phallapodeme, terminating in curved filaments, not inflated apically. Pregonite expanded. Postgonite narrow and apically out-turned, without an acute bend ( Fig. 6 View FIGURE 6 GH).
Female. Unknown.
Type material. HOLOTYPE: CHINA, Yunnan Province: Tengchong, 31.v.2007, Xingyue Liu (♂, CAU).
Distribution. Oriental: China (Yunnan).
Remarks. Cothornobata ingensfurca differs markedly from congeners by having a black fore tibia with a yellow tip, and a genital fork that is wider than the abdomen.
Etymology. The specific name refers to the large genital fork.
