description: TRICHADENOTECNUM CERROSILLAE SP. NOV.   Material examined: Holotype. Male. Mexico: Nuevo León, c. Cd. Contry, Monterrey, western slope of Cerro de la Silla, 700 m, 24.xii.1980, ANGA (UNAM). Paratypes. Mexico: 1 male, 6.3 mi SW Teziutlán, Puebla, 7000 ft, 19.viii.1958, H. Howden (ISU); 1 male, Nuevo León, 9 km NE San Antonio Peña Nevada, 1930 m, 25.viii.1979, ANGA & M. C. Herrera (UNAM); 1 male, 1 female, Nuevo León, western slope of Cerro de la Silla, path to the Arch, 900 m, 28.viii.1982, ANGA (UNAM).   
 Etymology: The specific epithet derives from ‘Cerro de la Silla’ (Saddle Mountain), an emblematic feature of Monterrey, Mexico, where the holotype of the species was collected.   
 Description: Male. Head. White in ground colour; vertical and orbital markings blackish brown; coronal suture black; frontal suture bordered with narrow pale brown band dorsally; frons with pair of blackish brown circular spots laterally; eye black, IO/D = 1.0; ocelli white, ocellar field black; antennal socket bordered with broad blackish brown band; gena blackish brown except rectangular white portion dorsally; postclypeus with c. eight rows of blackish brown spots at middle, fused with each other ventrally forming a large marking, ventro-lateral corner white, lateral margin of postclypeus blackish brown, dorsal margin without marking; anteclypeus brown. Antenna pale brown, pedicel and scape brown. Mouth parts blackish 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 three whitish oval spots on posterior regions of scutal lobes. 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. 17E). Rather sparsely covered with small spots. Spots in cell a 1 distinct, distal one larger, basal one paler. Opposing spots in cell r very small but distinct. Proximal band narrow, strongly constricted just beyond fork of M + Cu. Distal band narrow and faint in cell r 5, fragment of band in cell r 3 large. Spot on roof of cell m 3 large and dark. Submarginal spots apparent; spots in cells r 1, r 3 and m 3 small, sometimes indistinct. Marginal clouds faint. Hindwing. Hyaline, cell CuP with faint brownish spots; veins brown.   
 Abdomen. White, each segment with blackish brown band laterally, dorsum sparsely with irregular blackish brown markings, 6th to 8th venters blackish brown. Terminalia. Clunial arm (Fig. 23A) long and narrow, slightly sinuated, free from membrane apically, antero-ventrally with membranous lobe covered with fine setae. Anterior margin of 8th sternum (Fig. 23C) with semicircular extension medially; fusion with hypandrium narrow. Epiproct lobe (Fig. 23B) almost as long as wide, dorsal margin strongly sinuated, posterior surface almost flattened. Paraproct (Fig. 23A): ventro-lateral band indistinct; distal process broad. Hypandrium (Fig. 23C) with rugose region laterally; left process almost straight, directed postero-internally; right process projected outward, then strongly bent postero-internally near base; median tongue broadened apically, apical margin sinuated, dorsal keel triangular. Phallosome (Fig. 23D): pseudoparameres broadly separated, longer than wide, directed dorsally, apical margin rounded or somewhat truncate. Phallobase narrowing to pointed anterior end, anterior end with tiny triangular projection.   
 Length. B 2.2–2.5; FW 3.0–3.9; HW 2.1–2.9.   
 Female. Colour and general morphology almost as in male; eye IO/D = 2.0. Genitalia: Egg guide of subgenital plate (Fig. 24A) broadened at distal end, postero-lateral corners strongly angled, apical margin arched, with very shallow notch at middle; body of subgenital plate with pair of sclerites extending antero-medially. Dorsal valve of gonapophyses (Fig. 24B) with short distal process; posterior lobe of external valve strongly projected posteriorly. Internal plate as in Figure 24C.   
 Length. B 2.9; FW 3.1; HW 2.2.   
 Distribution: Mexico.
