Abstract

Four new species of Homidia are described from the Guangxi Zhuang Autonomous Region, China. Homidialongiantenna sp. nov. is characterised by its long antenna and slightly expanded post-labial chaetae; H.guangxiensis sp. nov. by the presence of smooth chaetae on the post-labium and posterior face of the ventral tube; H.huapingensis sp. nov. by the presence of smooth post-labial chaetae and pointed tenent hairs; and H.oligoseta sp. nov. by the pointed tenent hairs and fewer macrochaetae on Abdomen IV. Additions to the original description of Homidiaacutus Jing & Ma, 2022 are also provided.
