(Figs. 12–20)

Description. Measurements. Male, body length: 6.51 mm; head width: 1.70 mm; crown: length×width: 0.68× 0.93 mm; eye width: 0.57 mm; clypeus length: 1.29 mm; pronotum length×width: 0.67× 1.90 mm; mesonotum length: 0.97 mm. female, unknown.

External morphology. Crown light brown; eyes gray with longitudinal red band near inner margin (Fig. 14), ocelli dark brown (Fig. 13); clypeus brown, with apex and center pale; clypellus brown; gena pale yellow (Fig. 14). Pronotum yellowish brown with light brown knobs; mesonotum pale brown (Fig. 13). Forewing brown, with small ivory markings in outer anteapical cell and discal cell; venation fuscous, except A1, A2, R1, and R2+3 translucent (Fig. 12, 15). Legs pale (Fig.15).

Head narrower than pronotum, anterior margin rounded; crown wider than eye width, beyond eyes about 1/3 median length; coronal suture about half of median length; ocelli close to anterior margin of crown (Fig. 13). Face with clypeus long, lateral margins parallel, slightly concave in middle; clypellus short, inflated basally (Fig. 14). Crown, pronotum and mesonotum midline ratio about 1:1:1.4. Forewings typical.

Male genitalia. Pygofer in lateral view with caudoventral lobe broad (Fig.16), caudodorsal process broad and short (Fig.17). Segment X ventral processes absent; dorsal connective Y-shaped, with a very long projection basally (Fig. 17). Aedeagus tubular, long, reaching to near apex of ventral paraphysis; ventral paraphysis flat in lateral aspect, while broad basally, tapered to apical 1/3, apex extended laterally on both sides, transverse and slender with small process on left in dorsal view (Figs. 19). Style very slender, shorter than paraphysis, tapered distally; connective longitudinally rectangular (Fig. 18). Subgenital plate slender, apex truncate with tuft of fine long setae (Fig. 20).

Material examined. Holotype: male, CHINA: Mengla County, Menglun Town, Xishuangbanna, Yunnan Province, 781± 17m, 21°57′953″N, 101°12′305″E, 13 AUG 2011, coll. Zhang, Zhao & Chen, No. Hm 022017. (NWAFU).

Etymology. The specific epither is named after the locality of the holotype, Mengla County. Remarks. This species is similar to T. janssoni (Nielson, 1977: 88, Figs. 305–306), but differs in having the apex of the ventral paraphysis transverse, not recurved in lateral view.
