Male

Colouration (c. 4 years in alcohol). Head pale. Epicranial suture dark brown, light brown patches each side reaching ocellar tubercle and extending to posterior border of vertex, and mesial to each orbit. Eyes black. Ocelli pale, black centripetally. Frons with two median stripes and light brown mark. Antenna brown. Gena brown. Epistomal suture dark brown. Postclypeus pale with brown striation. Anteclypeus pale. Labrum and maxillary palp brown, apical segment of maxillary palp darkened. Thorax: dorsal lobe brown, pale along sutures. Pleura with traces of double brown stripes. Fore wing with dense dark brown markings as in Fig. 54. Hind wing (Fig. 55) suffused brown. Legs dark brown, pale between joints.

Morphology. IO:D 0.83, eyes prominent. Fore wing venation as in Fig. 54. Hypandrium (Fig. 56) (broken) symmetrical, serrated and spinous apically, medially with diamond-shaped hypandrial “tongue”, bordered with long setae. Phallosome (Fig. 57) open, curved. Epiproct as in Fig. 58. Paraproct (Fig. 59) with long apical spine, laterally with serrated sclerotized groove, field of about 23 trichobothria. Clunium (Fig. 60) with lateral spinous projection.

Dimensions. B 1.5; FW 2.0; HW 1.57; F 0.34; T 0.73; t 1 0.25; t 2 0.07; t 1 /t 2 3.57; Ct 17 (t 1) 2 (t 2); f 1 0.34; f 2 0.27; f 1 /f 2 1.26.

Remarks. The wing pattern of this species most resembles that of T. dolabratum Li & Yang, 1987 (China; placed in Loensia by Li, 2002), but the genitalia differ markedly. The median hypandrial tongue of T. dolabratum is surrounded by long setae, that are absent in the Sumatran specimen. The phallosome of T. dolabratum is a closed frame with a long pointed posterior projection, whereas that of T. muaraense is an open frame. Moreover, features of the epiproct and paraproct differ.
