Male unknown.
Female
Colouration (c. 4 years in alcohol). Head ground colour yellowish. Epicranial suture with dark brown uniform band each side. Confluent brown patches on posterior margin of vertex and mesial to each orbit. Eyes black. Ocelli pale, black centripetally. A narrow brown stripe from central ocellus toward each antennal socket. Frons with median Vshaped mark, a hooked-shaped brown mark each side between median V-shaped mark and antennal socket. Antennal socket bordered with brown band. Antenna light brown. Gena pale. Epistomal suture dark brown. Postclypeus pale with dark brown striations merging anteromedially and appearing as T-shaped mark. Anteclypeus dark brown on basal quarter, otherwise pale. Labrum dark brown. Maxillary palp pale, darkened apically. Thorax brown with small pale area near lobes. Fore wing (Fig. 24) suffused faint brown with brown pattern. Hind wing (Fig. 25) suffused with light brown. Legs whitish except coxa, apical band on femur and tarsal segment dark brown.
Morphology. IO:D 2. Fore wing venation as in Fig. 24. Subgenital plate (Fig. 26) posterior lobe rounded apically with long setae; main plate with broad sclerotized area, a field of short and long setae along midline of posterior lobe. Gonapophyses (Fig. 27) ventral valve elongate, pointed apically; dorsal valve broad, with long acuminate apex; outer valve broad, setose, with short conical posterior lobe. Spermapore plate (Fig. 27) heavily sclerotized anteriorly. Epiproct (Fig. 28) with fine long setae on the apical margin. Paraproct (Fig. 28) with field of about 20 trichobothria.
Dimensions. B 2.5; FW 3.22; HW 2.4; F 0.73; T 1.2; t 1 0.36; t 2 0.1; t 1 /t 2 3.6; Ct 21 (t 1) 2 (t 2); f 1 0.62; f 2 0.58; f 1 /f 2 1.06.
Remarks. This species closely resembles T. galihi (Endang et al., 2002) and T. apertum Thornton from Hong Kong in the form of the female subgenital plate. However, the ventral gonapophysis valve of T. kerinciense is longer than in those two species, and the spermapore plate lacks the lateral sclerotized hook apparent in those of T. apertum and T. galihi. It is attributed tentatively to Yoshizawa’s (2001) majus group.
Trichadenotecnum kerinciense appears to be a highland species; it was not taken below 850 m.
