description: TRICHADENOTECNUM CONCINNUM 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). 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) weakly sclerotized, not forming a free process apically, basally with membranous lobe. Eighth venter (Fig. 32C) with transverse, triangular sclerite, fused with hypandrium at middle. Epiproct lobe (Fig. 32B) slightly wider than long, slightly narrowing dorsally, posterior surface almost flattened. Paraproct (Fig. 32A): ventro-lateral band indistinct; distal process short. Hypandrium (Fig. 32C): 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): 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) 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) with long distal process; posterior lobe of external valve strongly projected posteriorly. Internal plate as in Figure 33C.   
 Length. B 2.2–2.6; FW 2.9–3.0; HW 2.1–2.3.   
 Distribution: Mexico.
