Male unknown.

Female

Colouration (c. 4 years in alcohol). Head ground colour yellowish. Epicranial suture dark brown, confluent brown patches each side reaching ocellar tubercle and extending to margin of vertex and mesial to each orbit. Eyes black. Ocelli pale black centripetally. Dark brown band from central ocellus toward anterior of each eye. Frons with median dark brown mark, two dark brown stripes lateral to this. Gena, epistomal suture, postclypeal striations, dorsal half of anteclypeus, labrum and maxillary palp dark brown. Thorax dark brown with small yellowish areas near lobes. Fore wing with dense dark brown markings as in Fig. 45. Hind wing (Fig. 46) suffused brown. Legs dark brown, pale between joints.

Morphology. IO:D 3.83. Fore wing venation as in Fig. 45. Subgenital plate (Fig. 47): apical lobe squarish, setose apically, median area close to main plate with field of very short setae; main plate with lateral oblong sclerotized area and field of long setae along midline of the plate and over sclerotized areas. Gonapophyses (Fig. 48): ventral valve elongate, pointed apically; dorsal valve broad, with long apical spine; outer valve slender, with long setae, apically with broad short spine. Epiproct as in Fig. 49. Paraproct (Fig. 49) with row of very long stout setae and field of about 20 trichobothria.

Dimensions. B 1.8; FW 2.37; HW 1.82; F 0.47; T 0.82; t 1 0.3; t 2 0.12; t 1 /t 2 2.5; Ct 19 (t 1) 2 (t 2); f 1 0.37; f 2 0.33; f 1 /f 2 1.05.

Remarks. The subgenital plate of this species suggests relationship with T. malayense New (1975) (Malaysia) and T. godavarense New (1971) (Nepal), T. sufflatum Li (1993) and T. himalayense Li & Yang (1987) (both from China, and both placed in Trichadenopsocus by Li, 2002). The fore wing pattern and female gonapophyses, however, differ markedly from these species.
