TRICHADENOTECNUM NEOLEONENSE View in CoL SP. NOV.

Material examined: Holotype. Male. Mexico: Nuevo León, Guadalupe, Rancho Alamillos, Ladera E Cerro de la Silla, 620 m, 31.vii.1979, ANGA ( UNAM) . Paratype. 1 female, same data as holotype ; 2 males, 2 females, same locality as holotype, 22.v.1977, ANGA ( UNAM) .

Etymology: The specific epithet refers to the Mexican state of Nuevo León, from where this species is only known presently.

Description: Male. Head. White in ground colour; vertical markings brown; orbital markings pale brown; coronal suture black; frontal suture very narrowly bordered with pale brown band; frons with two pairs of spots ventrally, lateral ones small, circular, dark brown, median ones tiny, pale brown; eye black, IO/D = 0.9; ocelli white, ocellar field black; antennal socket bordered with narrow brown band; postclypeus with 10 rows of blackish brown spots at middle, fused with each other ventrally forming a large marking, ventro-lateral corner white, dorsal region without marking; anteclypeus brown. Antenna pale brown, pedicel and scape darker. Mouth parts brown; 4th segment of maxillary palpus darker.

Thorax. Prothorax brown. Meso- and metathorax mostly brown except membranous regions white; mesoscutum pale, anterior surface of anterior lobe brown, mesopleuron with broad longitudinal white band medially; anterior margins of meso- and metas- cutellum blackish brown; metascutum with white spot medially, anterior part of lateral lobe white, lateral lobe with white spot posteriorly.

Legs. Coxae brown; hind femur brown, fore and middle tibiae brown basally, white distally and each with pair of dark brown spots on ventral surface; tibiae pale brown, with dark brown portion at distal end; tarsi brown.

Forewing ( Fig. 17G View Figure 17 ). Sparsely covered with small spots. Spots in cell a 1 distinct, subequal in size. Opposing spots in cell r distinct, posterior one very small. Proximal band narrow, strongly constricted at middle in cell CuA and just beyond fork of M + Cu. Distal band clear, narrow in cell r 5, broad in cell r 3. Spot on roof of cell m 3 large and dark. Submarginal spots apparent; spot in cell r 5 larger; spot in cell m 3 obscure. Marginal clouds faint, almost invisible except along each vein dark. Hindwing. Hyaline, cell CuP with large brown marking and few faint brown spots; veins brown.

Abdomen. White, each segment with blackish brown band except dorsum sparsely with blackish brown spots. Terminalia. Clunial arm ( Fig. 27A View Figure 27 ) long and narrow, slightly sinuate, forming pointed free process apically, antero-ventrally with fleshy lobe covered with fine setae. Anterior margin of 8th sternum ( Fig. 27C View Figure 27 ) with triangular extension; fusion with hypandrium broad. Epiproct lobe ( Fig. 27B View Figure 27 ) slightly wider than long, dorsal margin sinuated, posterior surface almost flat. Paraproct ( Fig. 27A View Figure 27 ); ventro-lateral band very short; distal process short. Hypandrium ( Fig. 27C View Figure 27 ) with weakly rugose region laterally; left process slightly curved at middle, directed posteriorly; right process projected outward, then strongly bent postero-internally near base; median tongue broadened apically, apical margin almost straight, dorsal keel triangular. Phallosome ( Fig. 27D View Figure 27 ): pseudoparameres broadly separated, short and narrow, longer than wide, gradually narrowing to rounded apex. Phallobase widest at anterior third, then narrowing to pointed anterior end.

Length. B 2.6–2.7; FW 2.8–3.2; HW 2.2–2.4.

Female. Colour and general morphology almost as in male; eye IO/D = 1.6. Genitalia: Egg guide of subgenital plate ( Fig. 28A View Figure 28 ) broadened near distal end, apical margin slightly hollowed; dorsal surface of egg guide sclerotized laterally; body of subgenital plate with pair of tongue-shaped extensions anteromedially. Dorsal valve of gonapophyses ( Fig. 28B View Figure 28 ) with short distal process; posterior lobe of external valve not strongly projected posteriorly. Internal plate as in Figure 28C View Figure 28 .

Length. B 2.7–3.0; FW 3.1–3.5; HW 2.3–2.5.

Distribution: Mexico.
