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.

Resumen: Se revisa las especies del género Yamatentomon en China y se describe Yamatentomon guoi sp. nov. del noreste de China. La nueva especie se caracteriza por un muy largo sensillum b en el tarso anterior, las setas A1 en tergitos I-VII cortas y delgadas, la presencia de P3a en tergitos IV-VII, 5 pares de setas A1 en tergito VII y la disposición de los poros en tergitos IV -VI. La nueva especie es similar a Y. kunnepchupi Imadate, 1964, pero se distinguen por la longitud de la sensilla b y e en el tarso anterior y la quetotaxia de los terguitos IV y V. Se provee códigos de barras de ADN para las especies nuevas para dar una referencia para su identificación en el futuro. Además, se redescribe Yamatentomon yamato (Imadate y Yosii, 1956) basado en especimenes recolectadas en la localidad de la especie tipo. También, se provee una clave actualizada de las especies de este género para el mundo.
