Comments. We reviewed the type specimens of Phrurolithus subnigerus Fu, Chen & Zhang, 2016, currently placed in Corealithus, and found that its morphological and genitalic characters are the same as those of Otacilia nigerus (Yin, 2012), particularly the shape of the copulatory ducts, connecting tubes, bursa, spermathecae, fertilization ducts, and copulatory openings. We therefore suggest that C. subnigerus syn. nov. should be a junior synonym of O. nigera . Furthermore, O. nigera should be transferred to Corealithus as a new combination, Corealithus nigerus (Yin, 2012) comb. nov. .
