TRICHADENOTECNUM CONCINNUM View in CoL SP. NOV.

Material examined: Holotype. Male. Mexico: Veracruz, Santiago Tuxtla, road to cerro El Vigía, 3 km W intersection with Hwy. 180, 13.vii.1973, ANGA ( UNAM) . Paratypes. Mexico: 1 male, same data as holotype ; 1 male, 1 female, Veracruz, road from Catemaco to Coyame, 2.6 mi from Catemaco , 16.vii.1973, J. R. Taber ( ISU) ; 1 male, 1 female, Veracruz, road to Cerro San Martín from San Andrés Tuxtla , 8 mi from Hwy. 180, 14.vii.1973, J. R. Taber ( ISU) .

Etymology: The specific epithet is taken from the Latin concinnus (= symmetric), indicating the symmetrical hypandrium of this species.

Description: Male. Head. White in ground colour; vertical and orbital markings blackish brown; coronal suture black; frontal suture bordered with blackish brown band dorsally; frons with pair of faint brown bands at middle and pair of blackish brown irregular bands laterally; gena white except ventral margin blackish brown; eye black, IO/D = 0.6; ocelli white, ocellar field black; antennal socket bordered with dark brown band; postclypeus with c. eight rows of pale brown spots dorsally, fused with each other ventrally forming a large blackish brown marking, dorsal margin and ventro-lateral corner without marking; anteclypeus brown. Antenna pale brown, scape and pedicel darker. Mouth parts pale brown; 4th segment of maxillary palpus dark brown.

Thorax. Prothorax brown. Mesonotum white; anterior surface of scutum pale brown; anterior margin of lateral lobe of scutum black; posterior region of lateral lobe of scutum pale brown; anterior margin of scutellum blackish brown; postnotum white. Metanotum pale brown, with white markings on anterior and posterior regions of lateral lobe of scutum; anterior margin of scutellum blackish brown. Mesopleuron white except dorsal third and ventral margin brown. Metapleuron brown except membranous region white.

Legs. Dark brown; fore femur, distal half of middle femur and all tibiae paler; distal tip of fore and middle femora with blackish brown spots ventrally; middle tibia with dark spot near distal end.

Forewing ( Fig. 17J View Figure 17 ). Spots in cell a 1 apparent, distal spot larger. Opposing spots in cell r large and distinct. Proximal band narrow, narrower in anterior half, with oval lighter pigmented portion in cell CuA. Distal band broad but faint. Spot on roof of cell m 3 small, distal half indistinct. Submarginal spots apparent; spot in cell r 5 larger; spot in cell m 3 indistinct. Marginal clouds faint. Hindwing. Hyaline, cell CuP with group of faint brown spots in distal half; veins brown.

Abdomen. White, each segment with blackish brown band. Terminalia. Clunial arm ( Fig. 32A View Figure 32 ) weakly sclerotized, not forming a free process apically, basally with membranous lobe. Eighth venter ( Fig. 32C View Figure 32 ) with transverse, triangular sclerite, fused with hypandrium at middle. Epiproct lobe ( Fig. 32B View Figure 32 ) slightly wider than long, slightly narrowing dorsally, posterior surface almost flattened. Paraproct ( Fig. 32A View Figure 32 ): ventro-lateral band indistinct; distal process short. Hypandrium ( Fig. 32C View Figure 32 ): left and right processes well developed, rising from postero-lateral corners, strongly curved, apices pointed and directed postero-internally; median tongue slightly broadened apically, with slight hollow medially on posterior margin, dorsal keel rounded. Phallosome ( Fig. 32D View Figure 32 ): pseudoparameres narrowly separated, broad and short, much wider than long, rounded apically. Phallobase narrowing to pointed anterior end, anterior end with triangular plate.

Length. B 2.2–2.3; FW 2.4–2.8; HW 1.8–2.1.

Female. Colour and general morphology almost as in male. IO/D = 1.9. Genitalia: Egg guide of subgenital plate ( Fig. 33A View Figure 33 ) widened near distal end, posterolateral corners rounded, apical margin rounded; body of subgenital plate with pair of broad median extensions anteriorly. Dorsal valve of gonapophyses ( Fig. 33B View Figure 33 ) with long distal process; posterior lobe of external valve strongly projected posteriorly. Internal plate as in Figure 33C View Figure 33 .

Length. B 2.2–2.6; FW 2.9–3.0; HW 2.1–2.3.

Distribution: Mexico.
