Aburina Möschler

Type species: sobrina Möschler, Africa.

Synonym: Ugana Swinhoe (type species piana Swinhoe = sobrina).

The genus is predominantly Afrotropical, the species below being the only Oriental representative.

The only Oriental member of this genus has facies rather like a delicate species of
Ugia, except the oblique postmedial has its pale component distal, rather than basal to, the dark component. The submarginal is pale and more irregular, less stepped than in Ugia (p. 187). On the underside, the discal marks are darker brown, contrasting with the pallor of these on the upperside, and there are curved dark postmedial and marginal lines, the former broader and more diffuse, displaced distally relative to the postmedials on the upperside. A distinctive generic feature is the elongation and forward direction of the labial palps, with scaling in the vertical plane dorsally rendering the third segment as deep as the second. The head, palps, fore- and mid-tibiae are diagnostically dark brown, conspicuous against the fauna of the rest of the body and wings. The male antennae are fasciculate.

In the African species, particularly the type species, the forewing postmedial is acutely angled subcostally, the submarginal markings are darker than the ground, and the darker fasciae on the underside coincide with, or are basal to those on the upperside. The male antennae are fasciculate but with one bristle much longer and thicker than the rest, giving them a bipectinate appearance. The structures of the labial palps, darkening of them, the head and the legs are as in the Oriental species.

The male eighth segment is of the framed corematous type, but the genitalia differ considerably in the African type species and the only Oriental species. The valves in the former are long, rather spindle-shaped, with a slight corona of setae at the rounded apex. The sacculus is represented by a longitudinal flange with a subbasal spine. The juxta is obscure but possibly of the inverted ‘V’ type. The aedeagus is short, broad, with a slightly serrate lobe at the apex, and the vesica is large, rather conical. In the Oriental species the genitalia and particularly valves, are distinctly elongate, the apices of the latter acute. There is a comparable saccular flange with a slight distal projection. The juxta is of the inverted ‘V’ type. The aedeagus is longer, slender, unornamented but the vesica is comparable.

In the female genitalia the ostium is situated between the seventh and eighth segments, but is within a distinctive scobinate sterigma in
sobrina that is lacking in the Oriental species. The bursa is short, broad, ovate to spindle-shaped, scobinate, lacking a ductus in sobrina, but elongate, narrow, unornamented, with a moderate ductus in the Oriental species.
