Fig. 5 , 12 , 19, 20 , 25 , 28 Diagnosis. Superficially, C. albistrigulana is nearly indistinguishable from C. osana ; both have conspicuous white costal strigulae on the forewing. In the male genitalia of C. albistrigulana the cucullus is much shorter and somewhat rhomboidal with a flattened outer margin compared to the longer, evenly curved outer margin of the cucullus of C. osana . The female genitalia of C. albistrigulana and C. osana are extremely similar, with a rectangular or U-shaped posterior margin of sternum 7. Description. Head . Vertex pale brown; frons lighter, with some orange; labial palpus ( Fig. 5 ) pale brown with narrow, longitudinal metallic blue stripe dorsally and slightly subdorsally along outer margin, bordered on each side by a narrow line of orange scales; third segment black; pedicel of antenna with subcircular patch of dark-brown scales. Thorax . Nota pale brown dorsally, with scales cream-tipped. Forewing ( Fig. 12 ) length 5.5–7.0 mm in male ( n = 10), 6.0–7.0 mm in female ( n = 5); costa slightly and evenly arched throughout; ground color pale reddish brown with cream olive hue; distal portion of costa and postapical portion of termen with narrow orange line; costal strigulae numerous, especially in basal 0.7, cream to white, divisions olive grey and pale orange; a slightly raised, roundish patch of silver opalescent scales near apex of discal cell, surrounded by small patch of black scales; similar patch near costa approximately 0.3 distance from base to apex, more elongate than rounded, less defined. Fringe pale reddish brown. Hindwing pale brown, paler in marginal region. Fringe pale-gray to cream. Abdomen . Brown. Male genitalia ( Fig. 19, 20 ) with uncus rounded-bifurcate apically, with cluster of long setae on each bifurcation; socii with fine hairs, broadest at base, digitate in distal 0.8, angled in basal 0.1; valva slightly broader basally, somewhat parallel-sided, without neck; costa with small, slightly hairy, triangular subbasal process without spine(s); weakly elevated lobe with a pair of large, stout setae beyond subbasal process; a pair of long, slender setae near outer edge of basal cavity; cucullus short, rhomboidal, occupying distal 0.40–0.45 of valva differentiated by slightly elevated ridge along basal edge, with small lobelike expansion bearing a single long seta near middle; ventral edge of cucullus mostly evenly rounded to apex, except for small, weakly concave region subapically; a few spines along outer edge; phallus short, broad, with slightly undulate dorsum bearing a few weak serrations in apical 0.25; vesica with a single small, socketed cornutus. Female genitalia ( Fig. 25 ) with papillae anales unmodified; sterigma large, weakly sclerotized throughout, ostium bursae flanked subterminally by large, posteriorly expanded lobes, notched postero-medially; antrum urn-shaped, broadest posteriorly, tapering proximally; ductus bursae narrow, straight in posterior 0.5, with slightly expanded portion ~0.6 distance from ostium to junction with corpus bursae, infrequently coiled one-half revolution (possibly as the result of mating), slightly broadened in anterior 0.33, with junction between ductus bursae and corpus bursae less defined; corpus bursae ovoid, finely punctate throughout, signum with single, large, spindle-shaped blade; posterior margin of segment 7 with deep U-shaped excavation with sclerotized edges.

Distribution and biology. Cosmorrhyncha albistrigulana is known from Guatemala , Costa Rica (provinces of Alajuela , Heredia ), and Brazil (states of Maranhão and Rondônia ), below 600 m elevation. It has been reared numerous times in Costa Rica from field-collected larvae on Dialium guianense (Fabaceae) . Etymology. The specific epithet refers to the bright white costal strigulae of the forewing. Remarks. This is another putatively widespread species that may represent more than a single entity. Although there is little doubt that specimens from Central America are conspecific, those from Brazil may not be. For example, in the male genitalia of specimens from Central America, the base of the large spine near the middle of the lower margin of the cucullus is sometimes contiguous with the margin of the cucullus ( Fig. 19 ), whereas in specimens from Brazil , the base of the spine is slightly separated from the lower margin of the cucullus ( Fig. 20 ). However, this may be, in part, an artifact of slide mounting, because in the NJ trees ( Fig. 1–3 ), specimens from Brazil cluster convincingly with those from Costa Rica .
