Diagnosis. Males of Strotarchus piscatorius resemble those of S. gandu n. sp. and S. minor by the wide, ventrally placed proximal fold of the reservoir, and those of S. silvae n. sp. by the extremely developed cymbium. They differ by the subtriangular course of the proximal fold of the reservoir and by the conspicuous, oblong tegular apophysis ( Figs. 106, 107 ). Females resemble those of S. gandu n. sp. by the median notch on the posterior atrial margin,
