Abstract
BACKGROUND: Jiangxi Province has gradually become a hotspot for research on the family Phrurolithidae Banks, 1892, with 64 new species discovered in the past five years. Notably, over half of the currently known Aculithus species (5 species) were recorded in this region. However, studies have primarily focused on southern Jiangxi, while northern Jiangxi and remote mountainous areas remain under-surveyed. Many unknown Phrurolithidae species are still likely to be discovered within the Province. NEW INFORMATION: Two new species, Aculithuslanguan Jiang & Liu, sp. nov. and A.ruijin Jiang & Liu, sp. nov., are described from Jiangxi Province, China. Morphological illustrations, SEM pictures, photos of live specimens and a distribution map are given. Additionally, a new combination, A.taoyuan (Fu, Chen & Zhang, 2016) comb. nov., is proposed. The total number of the known species of Aculithus from China is raised to 12, including the three species treated in the present paper.
