Bedosiallo moengus ( Schaus, 1928)

( Figs. 1B, 1C , 2 )

Among Bedosiallo St Laurent and Kawahara, 2018 , B. moengus is one of the largest species, and belongs to a species-group containing two large species with simple juxtal structures. Bedosiallo species are widely distributed in Central and South America but B. moengus is primarily known from Amazonian rainforest. We dissected a male specimen to compare to the male genitalia from an Amazonian specimen shown in St Laurent et al. (2018) and found no notable differences. Like in our discussion of Bedosia turgida (Schaus, 1910) above, eventually more in-depth analyses of genetics and morphology across wide ranging Bedosiini is warranted to identify the degree to which cryptic taxa should be recognized.

Lacosoma briasia . G. Macho de Lacosoma cf. raydela . H. Macho de Lacosoma vulfreda . Regardless, the female of B. moengus was previously unknown and we offer the description and figures of one belonging to the Colombian population below.

Description. Male. See Schaus (1928), and a detailed generic description in St Laurent et al. (2018). Female. Head: Coloration light brown-beige. Antennae bipectinate to tip. Eyes very large, comprising more than two-thirds area of head. Labial palpus coloration as for head; labial palpus three-segmented. Thorax: Coloration as for head, with broader scales. Legs: Coloration as for thorax, speckled with dark brown petiolate scales. Forewing: Length (base to apex): 35 mm; wingspan: 60 mm. Triangular with falcate apex. Ventrally ground color light brown-beige. Outer margin mostly convex except for concavity below the apex. Postmedial line straight, doubled, inner coloration pale brown and outer a darker brown. There is a light brown, inverted L-shaped line, originating from the costa, crossing the postmedial line and ending at tornus. Discal mark present as a bisected, rectangular hyaline patch. Wing outer margin is gray to dark brown. Ventrally, wings same coloration as dorsally but postmedial line lighter, with a horizontal line from costa to the postmedial line. Hindwing: Distally rounded, coloration and patterning as for forewing dorsum. Postmedial line outwardly convex, discal spot absent. Light brown vertical line originates at the apex and ends at the anal angle. Ventrally ground color same as in dorsum, postmedial line convex. Abdomen: Robust, extending beyond the anal angle of the hindwing, coloration mostly as for thorax. Laterally with dark brown line on both sides of abdomen. Genitalia: ( Fig. 2 ) VIII tergite as strongly sclerotized lobes at base of anal papilla. Ductus bursae membranous, roughly as long as terminal section of genitalia. Corpus bursae bag-like with no signum. Apophyses anteriores and the apophyses posteriores are equal in length. Lamella antevaginalis absent, lamella postvaginalis wrinkled and well sclerotized.
