Male genitalia

Black-brown with gonostyli slightly paler (Figs 32–33); pygofer higher than long and with posterior margin nearly straight in lateral view (Fig. 32); anal tube slightly transverse, 0.93 times as long as broad and with margins strongly projecting laterally on basal ⅔ into semi-circular lamina in dorsal view, apical ⅓ with lateral margins diverging towards apex (Fig. 33); apical margin acutely rounded in lateral view (Fig. 32); strong hump dorsally near base (Fig. 32); gonostyli elongate, 1.93 times longer than high, reaching apex of anal tube (Fig. 32); ventral margin broadly rounded to apex and dorsal margin strongly sinuate and with ante-apical notch in lateral view (Fig. 32); dorsal margin with strong, hook-shaped tooth at midlength pointing anteroventrally (Fig. 32); dorsal margin projecting laterally, semi-circular in dorsal view, with basal lobe and slightly folded internally near notch (Fig. 33).

Remarks

Male genitalia without basodorsal process on gonostyli.

Belbina recurva can be separated from all other species by having the anal tube produced into a semicircular lateral plate.
