Crenitis bicolor sp. n. from the Kamiesberg of South Africa (Coleoptera: Hydrophilidae)

摘要

Crenits Bedel is a small hydrophilid genus of 41 species (Hansen, 1999; Hebauer, 1994, 2005), distributed across Eurasia, Africa and the Americas. The genus is particularly diverse in temperate regions, with the eastern Palaearctic and Nearctic regions containing the highest concentrations of taxa. The eight described African species are all restricted to temperate South Africa, most being found within the winter rainfall area of the Western Cape (Hebauer, 1994). Here I describe a distinctive new species on the basis of specimens collected in the high Kamiesberg of Namaqualand in 2010.
