(Figs. 13 A–J, 14 E, F, 16 F, G)

Material. SRI LANKA, Sabaragamuwa prov., Millenium Foundation Orphanage, h= 90 m, 7°16'40'' N, 80°23'12'' E, 19–22 December 2012, coll. I. Melnik— 1 male (ZIN) .

Description. Male. Body comparatively flat (Fig. 16 G), as compared with Thorax species. General color yellowish; eyes black; head, pronotum and tegmina densely covered with black punctuations; tegmina also with scattered small black maculae (Fig. 16F, G). Surfaces smooth and lustrous, head, pronotum and tegmina strongly punctured; antennae (with exception of about 3 proximal segments) and maxillary palps dull. Head slightly longer than wide (Figs. 13 A, 16F); facial part with transverse impression between antennal sockets; ocellar spots large; distance between eyes 0.7 times of the eye length; distance between antennal sockets about 1.7 times of the scape length (0.8 mm); approximate length ratio of 3rd–5th segments of maxillary palps 1.1: 1: 1.2. Pronotum as in Fig. 16 G. Tegmina and wings completely developed, surpassing abdominal apex (Figs. 14 E, F, 16G). Tegmina flat and coriaceous, venation distinct; apex more rounded (Figs. 14 E, 16G), as compared with T. porcellana . Tegmina with costal field long and narrow, Sc thickened, branched apically; R with numerous anterior rami; R, M and CuA stems clearly visible, separated; CuP distinct; anal veins visible in posterior part of tegmen, where right tegmen overlapped by the left one at rest (in Fig. 14 E shown with dashed line). Wings (Fig. 14 F) similar to those of T. porcellana, but Sc weak, not interrupted in basal part; RA not numerous, partly irregular; M simple; CuA without complete (i.e. reaching the wing margin) veins; vein, probably corresponding to 1st plical vein sensu Rehn (1951) or CuP [probably CuP + A1 sensu Bey-Bienko (1950)], interrupted in basal part, with 2 or 3 short posterior branches. Anterior margin of fore femur armed as in type B, with 2 spines, including 1 apical one. Tibiae not thickened distally. Structure of hind tarsi similar to that of T. porcellana . Abdomen without visible specializations. Anal plate, cerci (Fig. 13 B) and hypandrium (Fig. 13 D), similar to those of T. porcellana . Paraprocts as in Fig. 13 C; pv —sclerites substituted by pillow-like membranous structures, densely covered with very small chaetae.

Male genitalia as in Fig. 13 E–J, similar to those of T. porcellana, but right phallomere (R+N) with caudal part of sclerite R1T (Fig. 13 E, c.p.R1T) less sclerotized; R4 weakly sclerotized, separated from R1T; "curved upward subsclerite" (Fig. 13 G, u.s.) and "elongated sclerite" (Fig. 13 H, e.scl.) of L2D (L1) weaker; sclerite L3 (L2d) without basal subsclerite (Fig. 13 I, J).

Measurements (mm). Head length: 3.0; head width: 2.8; pronotum length: 4.5; pronotum width: 5.8; tegmen length: 15.2; tegmen width (in place where CuP running into posterior margin of tegmen): 5.3.
