Belbina foliacea Lallemand, 1950: 84 (type in FSAG).

Cornelia foliacea – Lallemand 1959: 87, fig. 32a–c (key, description, lateral view of head and male genitalia). — Constant 2004b: 31 (listed).

Diagnostic characters

(1) disc of hind wings red ( Fig. 5A ); (2) carina above eye strongly expanded dorsad into foliaceous process ( Fig. 5C–E ); (3) cephalic process strongly curved dorsad ( Fig. 5D ); (4) tegmina variegated brown-olivaceous; (5) veins of tegmina elevated ( Fig. 5A ).

LT: ♂ (n = 1) 24.0 mm; ♀ (n = 1) 29.9 mm.

Material examined

Holotype

MADAGASCAR: ♂, [Maromandia, Madagascar, Lamberton] [Type.] [ Cornelia foliacea Lall., V. Lallemand det., 1954], 18°56’ S, 49°03’ E ( FSAG).

Paratype

MADAGASCAR: 1 ♀, no label, probably same data as holotype.

Male genitalia

The male genitalia were dissected and drawn by Henry Synave for Lallemand’s revision (1959). Only one gonostylus and the phallic complex were illustrated. The organs were preserved in a small glass vial under the specimen. The anal tube is missing and the pygofer is severely damaged. As it has been treated with potassium hydroxide, it is not possible to know the original colour.

Gonostyli elongate, 1.7 times longer than high and broadly rounded at apex in lateral view; ventral margin nearly straight; dorsal margin strongly sinuate basally and with a strong angle at basal third, then straight; strong lateral tooth directed posteroventrally along dorsal margin under angle ( Fig. 21 ).

Remarks

Male genitalia without a baso-dorsal process on the gonostyli.

Belbina foliacea can be separated from B. bergrothi , B. madagascariensis , B. nympha and B. recurva by the strong angle above the medio-dorsal tooth and the broadly rounded apex of the gonostyli.

Distribution

See Fig. 47 .
