Etymology: The specific epithet is taken from the Latin latus (= broad) + penna (= wing), indicating the wide forewing of this species. Description: Male . Head . White in ground colour and extensively marked with dark brown; vertical and orbital markings dark brown; coronal suture black; frontal suture dorsally bordered with dark brown band; frons with two pairs of dark brown bands, lateral pair smaller but darker; gena mostly dark brown with white portion medially; eye black, small, IO/D = 1.1–1.4; ocelli white, ocellar field black; antennal socket bordered with dark brown band; postclypeus with c. eight rows of blackish brown spots at middle, fused with each other ventrally forming a large T-shaped marking, ventro-lateral corner white; anteclypeus dark brown. Antenna brown, pedicel and scape darker. Mouth parts brown. Thorax . Prothorax brown. Meso- and metathorax mostly dark brown except membranous region white; dorsal surface of mesonotum paler, median and postero-lateral regions white, with pair of faint blackish spots at posterior end of anterior lobe. Legs. Brown; median part of fore femur and tibiae of all legs except distal tips paler. Forewing ( Fig. 5H ). Somewhat broad, moderately spotted. Spots in cell a 1 distinct, distant spot usually larger or sometimes almost equal in size. Opposing spots in cell r distinct but sometimes faint. Proximal band narrow and faint, darker and distinct in cell CuP, just below fork of M + Cu and around Rs-M fusion. Distal band broad and distinct. Spot on roof of cell m 3 usually small and indistinct in distal half. Submarginal spots distinct, spots in cells r 1 and m 3 fainter and sometimes indistinct. Marginal clouds indistinct. Hindwing. Hyaline, cell CuP with faint sparse spots or not; veins brown. Abdomen . White, each segment with irregular blackish brown band, thicker ventrally and laterally. Terminalia . Clunial arm variable in shape but usually short. Epiproct lobe ( Fig. 14D ) short, shorter than basal width, usually sharply narrowing to rounded or truncate narrow dorsal margin. Hypandrium ( Fig. 14E ): left process conical, strongly projected postero-laterally, slightly to strongly curved; right process triangular, weakly projected posteriorly; median tongue slightly to moderately constricted near middle, apical margin with triangular notch medially. Phallosome ( Fig. 14F ): pseudoparameres short and broad, expanded laterally, almost fused medially with shallow hollow posteriorly. Phallobase narrowing anteriorly, with triangular anterior end. Length . B 2.8–3.2; FW 4.6–5.5; HW 3.5–4.2. Female . Colour and general morphology almost as in male; eye IO/D = 2.2–2.3. Genitalia : Egg guide of subgenital plate ( Fig. 15A ) broad, broader than long, anterior margin somewhat rounded, anterior margin of body of subgenital plate almost straight, with narrow and deep median notch. Internal plate as in Figure 15B . Length . B 3.6–4.0; FW 4.8–5.5; HW 3.6–4.5. Distribution: Mexico .
