Abstract:
A new monotypic ground spider genus, Hotwheelsgen. nov., is described, with the type species H.sisyphussp. nov. (♂♀) from southwest China. This new genus is not assigned to any of the known subfamilies of Gnaphosidae, belonging only to the Echemus group of genera. It resembles Synaphosus Platnick & Shadab, but it can be differentiated by the presence of a median apophysis. Descriptions, illustrations and a records map are provided.
