Male genitalia

Very finely granulose, dark brown, with gonostyli slightly paler dorsally and ventrally ( Figs 29–30 ); pygofer higher than long and with posterior margin broadly sinuate in lateral view ( Fig. 29 ); anal tube elongate, 1.43 times longer than broad at apex and with lateral margins diverging on basal half, then broadly rounded in dorsal view ( Fig. 30 ); curved ventrally and with posterior margin acutely rounded apically in lateral view ( Fig. 29 ); gonostyli elongate, 1.63 times longer than high, not surpassing anal tube and broadly rounded at apex in lateral view ( Fig. 29 ); all margins broadly rounded except dorsal margin obliquely straight on basal half ( Fig. 29 ); lateral hook-shaped tooth at base of dorsal margin curved lateroventrally ( Fig. 29 ); gonostyli nearly not visible from above ( Fig. 30 ).

Remarks

Male genitalia without basodorsal process on gonostyli. Belbina nympha can be separated (1) from B. bergrothi by the less elongate gonostyli, without large pale marking ventrally and more broadly rounded apex, and the less elongate anal tube; (2) from B. foliacea by having gonostyli more broadly rounded apically and without a strong angle above the mediodorsal tooth; (3) from B. madagascariensis by having the margins of the anal tube rounded laterally and the dorsal margin of the gonostyli broadly rounded on the apical half; (4) from B. recurva by not having the anal tube produced into a semi-circular lateral plate.
