Abstract

ABSTRACT The millipede subfamily Pericambalinae Silvestri, 1909 is poorly understood and the taxonomic status remains controversial. Pericambalinae was regarded as either a subfamily of Cambalopsidae or an independent family. To address this issue, we conducted a molecular phylogenetic analysis and a morphological revision, and the genera and species from China are also revised. The results support the recovery of the family status, Pericambalidae, stat. nov. The morphological differences between Bilingulus Zhang & Li, 1981 and Parabilingulus Zhang & Li, 1981 are shown to be caused by post-embryonic development (anamorphosis and non-systemic metamorphosis) and both of these should be junior synonyms of Pericambala Silvestri, 1909 (Pericambala = Bilingulus, syn. nov. = Parabilingulus, syn. nov.). Three new combinations are proposed: Pericambala simplicia (Mauriès & Nguyen Duy-Jacquemin, 1997), comb. nov., Pericambala aramula (Zhang & Li, 1981), comb. nov. and Pericambala sinica (Zhang & Li, 1981), comb. nov. The mature specimens of Pericambala simplicia, comb. nov. and Pericambala aramula, comb. nov. were collected from the type localities and are described for the first time. A new species, Pericambala cordata, sp. nov. is described. After revision, Pericambalidae contains two genera and six species with one genus and four species recorded from China. Due to a deficiency in outgroup sampling, the phylogenetic status of Pericambalidae in the suborder Cambalidea remains uncertain. Variation of the gnathochilarium in Cambalidea is discussed and a key to the species of Pericambala in China is also provided. This research lays a foundation for further revision of Cambalidea in the future. ZooBank: urn:lsid:zoobank.org:pub:BDA46BCE-102B-45FE-A963-47F029A09E76.

重报卷腹蛛科，1909年11月(双足目:螺链目:卷腹蛛科)，并对中国的属种进行了修订

摘要千足亚科(Pericambalinae Silvestri, 1909)的分类地位尚存争议。扁蛇科被认为是扁蛇科的一个亚科或一个独立的科。为了解决这一问题，我们进行了分子系统发育分析和形态学修订，并对中国的属和种进行了修订。研究结果支持了该物种家族地位的恢复，Pericambalidae, stat11 .。Bilingulus Zhang & Li, 1981和Parabilingulus Zhang & Li, 1981之间的形态差异被证明是由胚胎后发育(畸形和非系统变态)引起的，这两者都应该是Pericambala Silvestri, 1909的初级同义词(Pericambala = Bilingulus, syn11 . = Parabilingulus, syn11 .)。提出了三种新的组合:糙皮草(Pericambala simplicia, mauri & Nguyen Duy-Jacquemin, 1997)，梳子。11月，阿兰包皮(Zhang & Li, 1981)，梳。[11 .]和《中草周参》(张黎，1981)，编。11 .单宁皮的成熟标本，梳状。11月和包皮，梳子。11月从类型地点采集，首次被描述。本文报道了一新种Pericambala cordata, sp. nov.。经订正，虎腹螨科有2属6种，其中中国有记录的有1属4种。由于外群采样的不足，蛇鞘亚目蛇鞘科的系统发育状况仍然不确定。本文讨论了冈比亚纲齿颌纲的变异，并提供了中国齿颌纲齿颌纲种的检索表。本研究为今后进一步修订冈比亚纲奠定了基础。ZooBank: urn: lsid zoobank.org:酒吧:bda46bce - 102 b - 45 - fe - a963 f029a09e76——47。

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
