A Review of the Shore-Fly Genus Psilephydra Hendel, 1914 (Diptera, Ephydridae) from Nepal

Abstract

Two new species of the shore-fly genus Psilephydra Hendel, 1914, Ps. montanasp. n. and Ps. rupicolasp. n., are described from Nepal (environs of Dhunche). Both species were found in the same habitat and were captured on moist cliffs in the mountains at the elevation of 2040 m a. s. l. Individuals of Ps. montana are easily differentiated from those of the other Psilephydra species by the presence of facial setae and by a characteristic shape of the gonite. Individuals of Ps. rupicola differ in a high gena, acinaciform gonite, and in the presence of 6 spines on the posteroventral surface of the fore femur. A key to the species of the genus Psilephydra is composed.
