Abstract

Two new species of the diving beetle genus Liodessus Guignot, 1939 are described from high mountain regions in Venezuela: Liodessus meridensis sp. nov. from Laguna de Mucabají, Mérida and L. venezuelensis sp. nov. from Laguna de Mucabají and below Pico Bolívar, Mérida. We delineate the species using morphological characters such as male genital structure and beetle size, shape and color. Mitochondrial cox1 sequence data provided an additional character source. Both new species occur at altitudes above 3,500 m and were collected in shallow water at the edge of high-altitude ponds.
