description: Phlebonotus pallens (Audinet-Serville, 1831)
(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.
