Etymology: The specific epithet refers to the denticles on the edge of the clunial arms and on the apex of the aedeagus. Description: Male . Head . White in ground colour; vertical and orbital markings large, blackish brown; coronal suture black; frontal suture bordered with brown band dorsally; frons with two pairs of pale brown bands; gena blackish brown with white spot medially; eye black, IO/D = 1.0; ocelli white, ocellar field black; antennal socket bordered with blackish brown band; postclypeus with eight rows of faint brown spots, fused with each other ventrally forming a large, blackish brown marking, ventro-lateral corner white; anteclypeus blackish brown. Antenna pale brown, scape and pedicel darker. Mouth parts blackish brown. Thorax . Prothorax blackish brown. Mesonotum pale brown; anterior surface of scutum blackish brown; anterior margin of lateral lobe of scutum black; anterior margin of scutellum blackish brown; postnotum brown. Metanotum brown, with pale oval spot on posterior region of each lateral lobe of scutum; medial lobe with white spot posteriorly; scutellum blackish brown. Meso- and metapleurites blackish brown except membranous region white. Legs. Blackish brown; tibiae and fore coxa paler; fore and middle femora with pale brown portions at middle and distal end. Forewing ( Fig. 36E ). Distal spot in cell a 1 large and dark, basal one small and faint. Opposing spots in cell r apparent but rather small. Proximal band broad but pale in posterior half, strongly constricted at anterior part of cell CuA, broadly interrupted around fork of M + Cu. Median spots sparse, some distal spots fused with each other, forming a large marking. Distal band broad but faint, especially in cell r 5 . Spot on roof of cell m 3 small, almost indistinct around M3 fork. Submarginal spots apparent; spot in cell m 3 smaller and paler. Marginal clouds apparent, darker along each vein. Hindwing. Hyaline; veins brown. Abdomen . White with irregular faint brown markings. Terminalia . Clunial arm ( Fig. 41A ) broad, axeshaped, distal part with rows of serrations and denticles. Anterior margin of 8th sternum ( Fig. 41C ) with broad triangular incision at middle, narrowly fused with hypandrium posteriorly. Epiproct lobe ( Fig. 41B ) long, much longer than wide, conical and pointed dorsally in posterior view. Hypandrium ( Fig. 41C ): left and right processes long, directed postero-internally, very slightly arched, gradually narrowing to pointed apices. Phallosome ( Fig. 41D, E ) with single posterior process apically denticulated. Phallobase almost parallel sided, widest near anterior end, anterior margin rounded. Figure 40. Male terminalia structures of Trichadenotecnum barrerai , showing terminalia in lateral view (A), epiproct in posterior view (B), hypandrium in ventral view (C) and phallosome in ventral (D) and lateral views (E); everted endophallus is not illustrated in D or E.
