Diagnosis.
Most readily distinguished from
B. gyona
and
B. pulcherrima
by its smaller size (orewing length 8.0 mm) and uniform width of the male valves, which are not expanded apically; and from
B. solisae
by having its hindwings tinged with russet towards the outer margin (cf. white in
B. solisae
).
Description
. Labial palpi upturned, dark russet, fading at third segment; thoracic collar dark; legs predominantly scaled pinkish, with greater proportion of white scaling on tibiae; one pair of mid-tibial and two pairs of hind-tibial spurs; abdominal scales pinkish, white at posterior margin of each segment.
Forewing.
Basal and medial areas deep russet in ground color; antemedial and postmedial areas pinkish with veins overlaid with white scales. Antemedial and postmedial lines tricolored towards inner margin, the white inner line fading towards costa, flanked by dark lines adjacent to the medial area and pinkish lines adjacent to basal and postmedial areas. Postmedian line incomplete, appearing to partially enclose cup-shaped wedge in medial area (cf. "una V" of
Köhler 1947
: 78). Postmarginal area similar to antemedial: predominantly pinkish, veins overlaid with white scales.
Hindwing.
Marginal area russet fading to white inwardly; subterminal band absent or not sharply defined.
Male genitalia
(Figs 13a, b). Valves of uniform width, neither constricted medially nor expanded apically; secondary projection from ventral surface less than half the width of the valve; inner margins of valves with lobes produced posteromedially towards juxta; valves setose apically, setae short; clasper fingerlike, arising medially, slightly over half the width of the valve; saccus rounded; pleural sclerite S-shaped; uncus of uniform width; phallus simple, without cornuti, vesica with slerotized basal cap bearing bearing ca. 7 denticles.
