摘要

本文描述了来自南中国海珊瑚礁的新属和新种。新属 Gothus 及其模式种 G. teemosp.根据形态学证据，我们暂时将该属归入 Euxanthinae Alcock, 1898 亚科。然而，基于 COI、12S、16S 和 H3 的分子系统分析表明，它与任何相关的亚科都没有形成稳定的单系群。根据形态学和分子证据，另一个物种 Actaeodes consobrinus（A. Milne-Edwards，1873 年）也被重新归入这个新属。

Morphological and molecular evidence for Gothus teemo gen. et sp. nov., a new xanthid crab (Crustacea, Brachyura, Xanthoidea) from coral reefs in the South China Sea, with a review of the taxonomy of Actaeodes consobrinus (A. Milne-Edwards, 1867)

A new genus and species within the family Xanthidae MacLeay, 1838, are described from coral reefs in the South China Sea. The new genus, Gothus, with its type species G. teemosp. nov., is distinguishable from allied genera by characteristics of the carapace, chelipeds, and male pleon. Based on morphological evidence, we tentatively place this genus within the subfamily Euxanthinae Alcock, 1898. However, molecular systematic analysis based on COI, 12S, 16S, and H3 indicates that it does not form a stable monophyletic group with any related subfamily. Another species, Actaeodes consobrinus (A. Milne-Edwards, 1873), is also reclassified into this new genus, based on both morphological and molecular evidence.

期刊介绍： Zoosystematics and Evolution, formerly Mitteilungen aus dem Museum für Naturkunde in Berlin, is an international, open access, peer-reviewed life science journal devoted to whole-organism biology. It publishes original research and review articles in the field of Metazoan taxonomy, biosystematics, evolution, morphology, development and biogeography at all taxonomic levels. The journal''s scope encompasses primary information from collection-related research, taxonomic descriptions and discoveries, revisions, annotated type catalogues, aspects of the history of science, and contributions on new methods and principles of systematics. Articles whose main topic is ecology, functional anatomy, physiology, or ethology are only acceptable when of systematic or evolutionary relevance and perspective.
