title: Paracerella Imadaté in China: the description of a new species and the analysis of genetic differences between populations (Protura, Acerentomata, Nipponentomidae).
abstract: The genus Paracerella Imadaté, 1980 is recorded from China for the first time, with the description of a new species, Paracerella sinensis sp. n. Paracerella sinensis is characterized by four pairs of A-setae on tergite I, the presence of setae Pc and P3a on tergite VII, eight A-setae on tergite VIII, the presence of seta Pc on both sternites VI and VII, and 4/2 setae on sternite VIII, which are different from all other members of the genus. The key to the four species of the genus is updated. In addition, DNA barcodes of four populations are sequenced and their genetic differences are analyzed.
