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..
