description: TRICHADENOTECNUM SPARSUM SP. NOV.   Material examined: Holotype. Male, Mexico: Durango, Reserva de la Biosfera La Michilía, Trampa Mesa del   
 Burro, 2500 m, 26.viii.1987, ANGA & IWB Thornton (UNAM). Paratype. 1 male, same data as holotype (UNAM).   
 Etymology: The specific epithet is taken from the Latin sparsus (= sparse), indicating the sparsely spotted forewing of this species.   
 Description: Male. Head. White in ground colour; vertical and orbital markings dark brown; coronal suture black; frontal suture dorsally bordered with narrow brown band; frons with two pairs of dark brown bands; gena mostly dark brown with white spot medially; eye black, small, IO/D = 1.6; ocelli white, ocellar field black; antennal socket bordered with dark brown band; postclypeus with c. eight rows of blackish brown spots at middle, fused with each other ventrally forming a large T-shaped marking, ventro-lateral corners white; anteclypeus dark brown. Antenna brown, pedicel and scape darker. Mouth parts dark brown.   
 Thorax. Prothorax dark brown. Meso- and metathorax mostly dark brown except membranous region white; dorsal surface of mesonotum mostly white, irregularly with some brown spots, anterior lobe with pair of pale brown markings, each with white circular marking medially, posterior margin of lateral lobe pale brown. Mesopleuron with longitudinal white band medially.   
 Legs. Dark brown; distal half of fore femur and tibiae of all legs except distal tips pale brown.   
 Forewing (Fig. 5G). Relatively narrow and sparsely spotted. Spots in cell a 1 distinct, nearly equal in size. Opposing spots in cell r small but distinct, widely separated from each other. Proximal band faint, distinct only in cell CuP and around vein Rs-M fusion. Distal band broad, faint to distinct. Spot on roof of cell m 3 variable. Submarginal spots distinct, spot in cell r 5 larger, spots in cells r 1 and m 3 hardly distinct. Marginal clouds indistinct. Hindwing. Hyaline, cell CuP with few faint spots; veins brown.   
 Abdomen. White dorsally, each segment with narrow blackish band, blackish brown ventrally. Terminalia. Clunial arm long, distal end pointed. Epiproct lobe (Fig. 14A) long and broad, longer than basal width, gradually narrowing to rounded dorsal margin. Hypandrium (Fig. 14B): left process conical, strongly projected posteriorly; right process small, hardly projected posteriorly; median tongue with broad base, then narrowing to basal quarter, almost parallel sided from basal quarter to distal quarter, then broadened apically; apical margin with deep triangular notch. Phallosome (Fig. 14C): pseudoparameres short and broad, expanded laterally, almost fused medially with shallow hollow between them. Phallobase narrowing anteriorly, with pointed anterior end.   
 Length. B 2.6–2.9; FW 3.8–3.9; HW 2.9–3.0.   
 Female. Unknown.   
 Distribution: Mexico.
