Revision of chinese yamatentomon (Protura: Acerentomata: Acerentomidae), with description of one new species, redescription of yamatentomon yamato, and key to world species

Abstract

Chinese Yamatentomon is revised and Yamatentomon guoi sp. nov. is described from northeastern China. The new species is characterized by the extremely long sensillum b on foretarsus, short and slender A1 setae on tergites I-VII, presence of P3a on tergites IV-VII, 5 pairs of A-setae on tergite VII, and pore arrangement on tergites IV-VI. The new species is similar to Y. kunnepchupi Imadaté, 1964, but can be distinguished by the length of sensilla b and e on foretarsus, and chaetotaxy of tergites IV and V. DNA barcodes for the new species are provided to give a reference for identification in the future. In addition, Yamatentomon yamato (Imadaté & Yosii, 1956) was redescribed based on the specimens from type locality. An updated key to the world species of the genus was also provided.
