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 View Figure 17 ). 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 View Figure 23 ) 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 View Figure 23 ) with semicircular extension medially; fusion with hypandrium narrow. Epiproct lobe ( Fig. 23B View Figure 23 ) almost as long as wide, dorsal margin strongly sinuated, posterior surface almost flattened. Paraproct ( Fig. 23A View Figure 23 ): ventro-lateral band indistinct; distal process broad. Hypandrium ( Fig. 23C View Figure 23 ) 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 View Figure 23 ): 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 View Figure 24 ) 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 View Figure 24 ) with short distal process; posterior lobe of external valve strongly projected posteriorly. Internal plate as in Figure 24C View Figure 24 .
Length. B 2.9; FW 3.1; HW 2.2.
Distribution: Mexico.
