TRICHADENOTECNUM CINTALAPENSE SP. NOV.

Material examined: Holotype. Male, Mexico: Chiapas, 35 km south of Cintalapa , 920 m 20.viii.1975, ANGA & B. García González ( UNAM).

Etymology: The specific epithet is the patronymic of Cintalapa, where the holotype was collected.

Description: Male. Head. White in ground colour; vertical and orbital markings large, blackish brown; coronal suture black; frontal suture bordered with blackish brown band dorsally; frons with two pairs of pale brown bands; gena blackish brown; eye black, IO/D = 1.0; ocelli white, ocellar field black; antennal socket bordered with blackish brown band; postclypeus with eight rows of blackish brown spots, fused with each other ventrally forming a large marking, lateral margin of postclypeus blackish brown; anteclypeus blackish brown. Antenna pale brown, scape and pedicel darker. Mouth parts blackish brown.

Thorax. Prothorax blackish brown. Mesonotum brown, medially with longitudinal white band; anterior surface of scutum blackish brown; anterior margin of lateral lobe of scutum black; anterior margin of scutellum blackish brown; postnotum brown. Metanotum brown, medially with longitudinal white band; anterior margin of scutellum blackish brown. Meso- and metapleurites blackish brown except membranous region white.

Legs. Blackish brown; tibiae paler; fore and middle femora with pale brown portions medially.

Forewing ( Fig. 36I ). Spots in cell a 1 apparent, basal one smaller and paler. Opposing spots in cell r apparent, anterior one small. Proximal band broad in posterior half, broadly interrupted just beyond fork of M + Cu, strongly constricted near anterior end in cell CuA, including broad light pigmented area. Median spots dense, some spots fused with each other and forming large marking. Distal band broad but faint. Spot on roof of cell m 3 long. Submarginal spots apparent; spot in cell r 1 small; spot in cell m 3 paler. Marginal clouds broad and dark. Hindwing. Hyaline with faint brown markings in cell CuP; veins brown.

Abdomen. White, sparsely with irregular brown markings. Terminalia. Clunial arm ( Fig. 46A, B ) broadened and forming free process apically, strongly bent inward near apex, apical region with dorsal tongue-like projection and distal pointed process, distal margin serrated. Anterior margin of 8th sternum ( Fig. 46D ) widely but shallowly incised. Epiproct ( Fig. 46A, C ) chair-shaped, postero-dorsal margin with small projection; epiproct lobe small, conical. Paraproct ( Fig. 46A ): ventro-lateral band broad and short, triangular; distal process long, directed posteriorly. Hypandrium ( Fig. 46D ) almost symmetrical; left process conical, directed posteriorly; right process broad and lamellate, trapezoidal, its distal margin slightly sinuated; median tongue square-shaped, slightly wider than long in ventral view. Phallosome ( Fig. 46E, F ): pseudoparameres needle-like, rather short. Aedeagus broadly sclerotized, long, strongly projected postero-ventrally, apical region V-shaped in cross section, with two longitudinal rows of denticles at middle.

Length. B 2.5; FW 2.9; HW 2.3.

Female. Unknown.

Distribution: Mexico.
