Two new species of Tomocerus (Ocreatomurus) Yu, 2023 are described from Guangdong Province, southern China: Tomocerus (Ocreatomurus) subtropicus sp. nov. from Nanling Mountain and Tomocerus (Ocreatomurus) pani sp. nov. from Nankunshan Mountain. Tomocerus (O.) subtropicus sp. nov. closely resembles T. (O.) pseudocreatus Yu, 2018, but can be distinguished primarily by cephalic, Th. II, and manubrial chaetotaxy. Tomocerus (O.) pani sp. nov. is most similar to T. (O.) nan Yu, Yang & Liu, 2018, but differs mainly in cephalic and furcal chaetotaxy, as well as the density of denticles on dental spines. Although the two new species share some morphological characters, they can be separated from each other by Th. II chaetotaxy, dorsal scaling of manubrium, and shape of prominent chaetae on dens. A key to the species of Ocreatomurus with two large terminal dental spines is provided.
