Abstract:
Four species of the genus Ceratophysella living on mushrooms are reported from China, including a new species, Ceratophysellaskarzynskii Weiner & Sun, sp. n., which is described from alpine mushrooms. The new species belongs to the Ceratophysella group of species with a dorsal chaetotaxy of type B and differs from the other species in a combination of characters. Ceratophysellaskarzynskii sp. n. is distinguished by its small body size (maximum length 1.09 mm), number of peg-like s-chaetae (30-32) in the ventral sensory file, the trilobed apical vesicle of antennal segment IV, five modified chaetae on dens, and serrated dorsal chaetae. A key to the Chinese species of the genus has been provided.
