Six New Species of Genus Pedetontus Silvestri, 1911 (Microcoryphia: Machilidae), from Southern China.
Bristletails (Microcoryphia) represent a relatively understudied group of class Insecta. These wingless hexapods, which retain numerous plesiomorphic structures, remain less well understood compared to most other insect lineages. Through detailed morphological examination of specimens collected from southern China, we describe six new species (Pedetontus (Verhoeffilis) eleganssp. n. from Zhejiang; P. (V.) hezhouensissp. n., P. (V.) jinxiuensissp. n., and P. (V.) nanningensissp. n. from Guangxi; and P. (V.) shenzhenensissp. n. and P. (V.) xanthospilussp. n. from Guangdong) of subgenus Verhoeffilis Paclt, 1972. This subgenus is distinguished from other members of the Petrobiinae by several diagnostic features: paired ocelli shoe-shaped (fusiform-shaped) and submedian; two pairs of retractile vesicles on abdominal segments II-V; parameres restricted to coxite IX; penis opening small and apical; male genitalia not exceeding coxite IX; and ovipositor of primary type. The new species can be distinguished from known species and each other by the morphology of the compound eyes, maxilla, labial palps, legs, and genitalia; here, we provide detailed illustrations, tables, and descriptions. Furthermore, we sequence the COX1 gene to construct a phylogenetic tree of Microcoryphia. This contribution increases the total number of reported Pedetontus species in China to seventeen.

期刊介绍:
Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
