Diagnosis. Bleptina flavivena is most closely related to Bleptina verticalis , described below, and is distinguished from it by the dark gray-brown wing color of B. verticalis , versus the light brown color of B. flavivena . Externally, B. flavivena , and B. hydrillalis Guenée , (described from Haiti and extralimital to the US) look almost identical. Among other differences in male and female genitalia, B. flavivena can be distinguished from both B. verticalis and B. hydrillalis by the male valves, which are symmetrical in B. verticalis and asymmetrical in the other two species.

Description. Antennae filiform, ciliate; head, vertex, thorax, and abdomen beige with scattered black scales; tuft of black and beige scales on terminal segment of labial palps. Dorsal forewing (both sexes). Forewing length 10–11 mm. Ground color light brown with scattered black and darker brown scales, especially between the postmedial line and the outer margin; thin basal line light beige, bordered basally with brown scales, extends perpendicular to posterior margin; straight antemedial line light beige, bordered distally with brown scales extends perpendicular to posterior margin before bending basally at costa; postmedial line light beige, thinly bordered basally with brown scales, bends basally to costa above reniform spot; light beige submarginal line bends distally into cell M3; tiny orbicular spot black or ochre; reniform spot shaped like an inverted comma, either solid black or ochre, with a black dot in center; terminal line a series of brown spots between veins; fringe brown; all forewing veins lightly highlighted with ochre scales. Dorsal hindwing. Ground color beige, lightly suffused with dark brown scales basally, becoming solid dark gray brown in postmedial area; obscure discal lunule brown; terminal line a series of dark-brown crescents between veins; fringe with scattered dark-brown and light-gray scales. Male genitalia ( Fig. 55 View Figures 55–60 ). Valves symmetrical, long, and relatively narrow, sacculus bulging ventrally at base of valve; apex drawn dorsally to a sharp point, the valve otherwise unarmed. Uncus long, curved downward, swollen in mid section with pointed tip. Vesica with small, scobinate, bulbous basal section that is drawn to form a long process that narrows toward tip; an elongate ventral diverticulum leads to ductus seminalis. Female genitalia ( Fig. 107 View Figures 105–113 ). Ovipositor lobes setose, extending slightly distally at apex; ostium bursae scobinate; short, membranous ductus bursae terminates at bulbous part of appendix bursae from which a coiled diverticulum narrows to ductus seminalis; posterior corpus bursae a long, narrow tube connecting bulbous anterior section of corpus bursae to appendix bursae; this tube with many ridged sclerites extending its entire length, terminating in a concave, scobinate disc on ventral side of corpus bursae; anterior section of corpus bursae encircled by a narrow sclerite, from which about 14 short, knife-like cornuti extend into the corpus bursae.
