TRICHADENOTECNUM BARRERAI SP. NOV.

Material examined: Holotype. Male, Mexico: Chiapas, Reserva de la Biósfera El Triunfo, Ca. Sta. Rita. Vereda hacia Cañada Honda , 1860 m, 6.v.1993, ANGA & E. Barrera ( UNAM).

Etymology: The specific epithet honours Ernesto Barrera (Instituto de Biología, UNAM), one of the holotype collectors, friend and colleague of ANGA.

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 = 1.2; 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. 36D ). Spots in cell a 1 small, basal one faint. Opposing spots in cell r large, posterior spot placed proximal to anterior one. Proximal band broad in posterior half, interrupted just beyond fork of M + Cu, strongly constricted at anterior end in cell CuA, including circular light area. Median spots sparse. Distal band broad. Spot on roof of cell m 3 broad and dark. Submarginal spots apparent, large; spots in cell r 5 and m 1 larger than others; spot in cell m 3 smaller and paler, partly fused with spot on roof of cell m 3. Marginal clouds apparent, dark. Hindwing. Hyaline with faint brown marking in cell CuP, with longitudinal brown marking in cell r 1 along R1; veins brown.

Abdomen. White, each segment with blackish brown band ventrally, extending to lateral region. Terminalia. Clunial arm ( Fig. 40A ) broad, axeshaped, distal part covered with small denticles. Anterior margin of 8th sternum ( Fig. 40C ) with shallow incision at middle, broadly fused with hypandrium poseriorly. Epiproct lobe ( Fig. 40B ) semicircular in posterior view, dorsal margin with pair of tongue-like lobes projected dorso-laterally. Hypandrium ( Fig. 40C ): left and right processes long, directed postero-internally, then slightly arched, and directed inward apically, slightly broadened near apices, pointed at apices. Phallosome ( Fig. 40D, E ) with pair of short, needle-like processes closely approximated. Phallobase almost parallel sided, widest near anterior end, anterior margin slightly concave.
