Diagnosis
Generally dark brown. Metope and coryphe joined at nearly right angle (in lateral view). Metope with very weak and short median carina and weak sublateral carinae. Phallobase with median groove ventrally; each dorso-lateral phallobase lobe with short horn-shaped process apically. Aedeagus with pair of long ventral hooks (4 /5 of aedeagus length) arise subapically. Style with nearly straight hind margin. Male anal tube distinctly enlarged from base to apex (in dorsal view).
Etymology
The species is named after the type locality.
Type material
Holotype MALAYSIA • ♂; “ Sabah: Tawai / Plat. 1300 ft, / 8 km S. Telupid / 8.IX.1977 ” // “ M.E. Bacchus / B.M. 1978-48 ”; BMNH.
Description
Male
MEASUREMENTS. Total length (forewing apices curved): 2.8 mm.
STRUCTURE. Metope slightly depressed below upper margin, with very weak and short median carina and weak sublateral carinae running from upper margin to slightly beyond eyes, but not reaching metopoclypeal suture (Figs 3C, 4F). Metope and coryphe joined at nearly right angle (in lateral view) (Fig. 3B). Coryphe transverse, nearly 2.5× as wide as long at midline; anterior margin nearly straight; posterior margin concave (Fig. 3A). Coryphe longitudinally striated medially, with pair of weak bulges laterally. Postclypeus with smooth median carina. Pronotum 0.5 × as long as coryphe at midline, without bulges or carinae. Mesonotum 4 × as long as pronotum, with fine median carina and pair of lateral bulges. Forewings without bulges. Hind tibia with two lateral spines above middle and with five apical spines. First metatarsomere slightly longer than second one, but distinctly wider, with long setae ventrally and with two latero-apical and five intermediate spines. Second metatarsomere with two latero-apical spines only.
COLORATION (Fig. 3). General coloration dark brown, with black punctuation. Eyes light. 3 rd segment of rostrum light brown outside and dark brown behind. Forewings with light yellow spots in cells of apical part of clavus and ventro-apical half of corium. Forewing appendix (hardly visible on left wing on Fig. 3A) light brown yellowish from apex of clavus to dorso-lateral angle. Hind femora and tibiae brown. Apices of leg spines black.
MALE TERMINALIA (Fig. 7). Pygofer vertically elongate, with convex hind margins. Anal tube nearly twice as long as wide medially, distinctly enlarged from base to apex (in dorsal view) (Fig. 7C). Anal column long and narrow, not surpassing posterior margin of anal tube (Fig. 7C–D). Phallobase vertically elongate, narrow, curved (in lateral view), with median groove ventrally; each dorso-lateral phallobase lobe truncate apically, with short horn-shaped process (Fig. 7A–B). Ventral phallobase lobe short and wide, widely and deeply concave apically (Fig. 7C). Aedeagus with pair of long ventral hooks (4 /5 of aedeagus length) arising subapically and with several notches apically. Style with nearly straight hind margin (in lateral view) (Fig. 7E). Capitulum on distinct neck, with wide lateral tooth, not narrowing apically (in dorsal view) (Fig. 7F).
Female
Unknown.
