Discovery of the Skiff Beetle Genus Yara Reichardt and Hinton (Coleoptera: Myxophaga: Hydroscaphidae) in Venezuela, with description of a new species

摘要

The Neotropical skiff beetle genus Yara Reichardt and Hinton is recorded from Venezuela for the first time, marking the first discovery of the genus since its original description in 1976. The Venezuelan species, Yara maculata Short, Joly, and Garcia, new species, is described and illustrated, bringing the total number of species in the genus to three. It is currently known from several localities along the northwestern edge of the Guiana Shield. The presence of a mat of recumbent setae on tergite IV, often considered diagnostic for the family, is found to be absent in Yara. A key to the three species is provided as well as observations on the habitat and seasonality of the new species.
