TRICHADENOTECNUM TUITENSE SP. NOV.

Material examined: Holotype. Male, MEXICO: Jalisco, c. 20 km E of El Tuito, road to El Cuale, 3.xii.1980, ANGA ( UNAM).

Etymology: The specific epithet makes reference to the type locality.

Description: Male. Head. White in ground colour; vertical and orbital markings pale brown; coronal suture black; frontal suture bordered with narrow brown band dorsally; frons with two pairs of brown bands, median pair paler dorsally, lateral pair darker; gena mostly white, dorsal and ventral margins bordered with brown band; eye black, small, IO/D = 1.6; ocelli white, ocellar field black; antennal socket bordered with brown band; postclypeus with c. 10 rows of blackish brown spots, faint near dorsal margin, fused with each other ventrally forming a T-shaped large marking, ventro-lateral region white; anteclypeus brown. Antenna pale brown, pedicel and scape brown. Mouth parts pale brown.

Thorax. Prothorax brown. Meso- and metathorax mostly brown except membranous regions white; mesoscutum paler; mesopleuron with broad longitudinal white band at middle; dorsal half of meso- and metapleurites darker.

Legs. Brown; all tibiae paler, with darker portions near distal ends.

Forewing ( Fig. 5F ). Rather sparsely spotted. Spots in cell a 1 distinct, distal one large. Opposing spots in cell r distinct but small. Proximal band narrow but distinct, paler in cell CuA, broadly interrupted just beyond fork of M + Cu. Distal band faint but distinct. Spot on roof of cell m 3 distinct but small. Submarginal spots apparent; spot in cell r 5 larger than others; spots in cell r 1, m 1 and m 3 small, sometimes indistinct. Marginal clouds almost invisible, slightly distinct at distal end of each vein. Hindwing. Hyaline, cell CuP with pale markings basally; veins brown.

Abdomen. White, with brown markings irregularly. Terminalia. Clunial arm short and narrow. Epiproct lobe ( Fig. 13D ) long, almost as long as basal width, almost parallel sided basally, then gradually narrowing to truncate dorsal margin. Paraproct: ventrolateral band short, triangular; distal process long, directed upward. Hypandrium ( Fig. 13E ) symmetrical, without narrow membranous region anterior to median tongue socket; left process conical, projected posteriorly; right process less projected; median tongue with broad base, gradually narrowing to distal quarter, then slightly broadened, distal quarter parallel sided, distal margin with broad and shallow notch. Phallosome ( Fig. 13F ): pseudoparameres short and broad, strongly expanded laterally, broadly separated from each other. Phallobase almost parallel sided on posterior two-thirds, anterior tip with tiny process.

Length. B 2.7; FW 3.1; HW 2.3.

Female. Unknown.

Distribution. Mexico.
