description: TRICHADENOTECNUM MACULATUM SP. NOV.   Material examined: Holotype. Male. Mexico: Nuevo León, 5 km W of Ciénega, hacia Laguna de Sánchez, 1200 m, 25.v.1977, ANGA (UNAM). Paratypes. 1 female, same data as holotype; 1 male, 1 female, Nuevo León, 10 mi E Iturbide, Hwy. 60, 13.vi.1962, J. Campbell (ISU).   
 Etymology: The specific epithet is taken from Latin macula (= spotted), indicating the heavily spotted forewing in this species.   
 Description: Male. Head. White in ground colour; vertical and orbital markings pale brown; coronal suture black; frontal suture very narrowly bordered with pale brown band dorsally; frons with two pairs of pale brown spots ventrally; eye black, IO/D = 1.0; ocelli white, ocellar field black; antennal socket bordered with dark brown band; postclypeus with c. eight rows of pale brown spots at middle, fused with each other ventrally forming a large blackish brown marking, ventro-lateral corner white, lateral margin of postclypeus brown, dorsal margin without marking; anteclypeus brown. Antenna pale brown, pedicel and scape darker. Mouth parts dark brown; third segment of maxillary palpus pale brown.   
 Thorax. Prothorax brown. Mesonotum white; anterior surface of scutum brown; anterior margin of lateral lobe of scutum black; posterior region of scutum with pair of brown markings at middle; scutellum white, median part and anterior margin brown; postnotum brown. Metanotum brown, with pair of whitish oval spots on posterior regions of lobes of scutum, lateral corner white. Meso- and metapleurites brown with longitudinal white band medially.   
 Legs. Coxae dark brown; femora brown except middle part of fore and middle femora white; tibiae pale brown, with darker portion near distal ends; tarsi brown.   
 Forewing (Fig. 17F). Densely covered with small spots. Spots in cell a 1 distinct, basal one smaller. Opposing spots in cell r apparent for anterior one but posterior one very small and less distinct. Proximal band broad, strongly constricted around fork of M + Cu, with elongate paler pigmented area in cell CuA. Distal band somewhat indistinct in cell r 5, band in cell r 3 distinct. Spot on roof of cell m 3 large. Submarginal spots diffuse; spot in cell r 5 larger than others and distinct; spots in cell m 1, m 2 and m 3 small, sometimes indistinct. Marginal clouds clear, darker along veins. Hindwing. Hyaline, extensively covered with pale brown spots, some spots fused with each other to form a large marking in cell CuP; veins brown.   
 Abdomen. White, each segment with blackish brown band. Terminalia. Clunial arm (Fig. 25A) long and narrow, slightly arched, forming pointed free process apically, antero-ventrally with fleshy lobe covered with fine setae. Anterior margin of 8th sternum (Fig. 25C) concave; fusion with hypandrium very narrow. Epiproct lobe (Fig. 25B) expanded dorsally, wider than long, dorsal margin slightly arched, with rounded projection at middle, posterior surface almost flattened. Paraproct (Fig. 25A): ventro-lateral band short, triangular; distal process broad. Hypandrium (Fig. 25C) with weakly rugose region laterally; left process sinuate, directed postero-externally at apex; right process of almost equal width from base to apex, projected outward, then strongly bent posterointernally near base, with few denticles at apex; median tongue narrowing medially, then broadened apically, apical margin almost straight, dorsal keel triangular. Phallosome (Fig. 25D): pseudoparameres widely separated, longer than wide, directed posteriorly, apical margin rounded or somewhat truncated. Phallobase widest at anterior two-fifths, then narrowing to pointed anterior end.   
 Length. B 2.6–2.9; FW 3.0–3.7; HW 2.2–2.8.   
 Female. Colour and general morphology almost as in male; eye IO/D = 1.9. Genitalia: Egg guide of subgenital plate (Fig. 26A) widened near distal end, postero-lateral corners rounded, apical margin only slightly arched; body of subgenital plate with pair of broad extensions of sclerite antero-medially. Dorsal valve of gonapophyses (Fig. 26B) with long distal process; posterior lobe of external valve strongly projected posteriorly. Internal plate as in Figure 26C.   
 Length. B 2.8–3.0; FW 3.2–3.8; HW 2.1–2.9.   
 Distribution: Mexico.
