Diagnosis

Males of Umbyquyra sapezal gen. et sp. nov. have a strong procurve projection of the cephalic region resembling those of U. palmarum gen. et comb. nov. but differ by the two long stretch marks ( Fig. 5B ) and palpal bulb with the most enlarged A and SA keels ( Figs 9A , 10 A–B).

The species epithet is a noun in apposition taken from the type locality.
