Like the previous species, this new species belongs to the apodemi species group. Among this group the closest species is Afrolistrophorus punctatus Fain and Lukoschus from Spalax leucodon Nordmann ( Rodentia : Spalacidae ) from Hungary ( Fain & Lukoschus 1983 ). A. punctatus is known only from the holotype female collected from a museum specimen; therefore, this host record could be accidental. In females of both species, setae ps1 are absent and setae ps2 present, setae d III and IV are much shorter than the respective tarsi, excluding pretarsus, and the opisthosoma has no ventral scales or only posses a few scales. In females of A. saxatilomys sp. n. , the body is 485–525 long, the postscapular shield is without the median longitudinal band, the posterior end of the opisthonotum is without sclerotized patches, and a few verrucae are present ventrally between levels of trochanters III and IV. In the female of A. punctatus , the body is 425 long, the postscapular shield has the median longitudinal band, the posterior end of the opisthonotum bears a pair of the sclerotized patches, the hysterosomal venter is devoid of any verrucae or scales. In addition, the dorsal shields of A. punctatus have narrower and less numerous striations than in the new species. Males of A. saxatilomys sp. n. resemble males of Afrolistrophorus apodemi Fain known mainly from species of the genus Apodemus ( Rodentia : Muridae ) ( Fain 1981b ; Dubinina 1998 ). In males of both species, the hysteronotal shield is completely striated and the supranal concavity is small and rounded in outline. Males of the new species differ from those of A. apodemi by having narrower transverse bands on the postscapular shield and the presence of the ventral membrane on tarsus III. Etymology. The specific epithet derives from the generic name of the host and is a noun in apposition.
