Abstract

Ceratophysella mediolobata Nakamori, sp. nov., obtained from fungal sporocarps in Akita, northern Japan, is described herein. Ceratophysella liguladorsi (Lee, 1974) has been obtained from fungal sporocarps in the Ryukyus, southern Japan, as the first record from Japan. These species and Ceratophysella tergilobata (Cassagnau, 1954) are similar to each other in having a central projection on abdominal segment V, but C. tergilobata can be distinguished from the other two species by having one sublobal hair on the maxillary outer lobe (two sublobal hairs in the other species), and C. mediolobata sp. nov. can be distinguished from C. liguladorsi by the absence of third setae in the posterior-row on abdominal tergum IV (present in C. liguladorsi). Partial regions of the mitochondrial cytochorome c oxidase subunit 1 and 16S ribosomal RNA genes of C. liguladorsi and C. mediolobata sp. nov. were sequenced for DNA barcoding.
