Bardaxima subrutila ( Dognin, 1908)

Figs 21, 22, 54–56

Gisara subrutila Dognin, 1908: 171 . Lectotype male, FRENCH GUIANA: St. Laurent du Maroni ([Le Moult]) (USNM), designated by Schintlmeister (2016: 504) [examined].

Diagnosis. Male ( Fig. 21) FW length 25 mm (58 mm wingspan), female ( Fig. 22) FW length 30 mm (68 mm wingspan). FW olive fuscous; basal band reduced to a thin, well defined, black line; small, vertical, black dash at end of cell; female with white patch on tornus. HW fuscous. Abdomen fuscous dorsally, pale yellow ventrally; fuscous band dorsally along middle, broader at base, tapering to 5 th segment, remaining segments banded fuscous on articulations. Distal margin of 8 th male sternite ( Fig. 56) with a deep incision towards a heart-shaped structure at middle; proximal margin with pair of long, thin apophyses. Male genitalia ( Fig. 54): uncus branched into pair of curved, laterally flat processes. Valva short, triangular, base wider than length; costa slightly sinuate; sacculus narrow, as long as valva, rounded apically. Aedoeagus ( Fig. 55) short, broadly expanded distally into a complex structure.

Material studied. Type; 3 males (g.s. 5609), 3 females ( VOB); 1 male, 1 female ( AMC) .

Distribution. French Guiana and Brazil, in the Amazon region, south to Bahia.

Remarks. Presumably related to B. ionia but easily distinguished by the thin black line at base of FW, and the short, vertical, black line at end of cell, and by the unique shape of genitalia, as easily seen in the illustrations.
