ABSTRACT
The fur-mite genus Soricilichus Fain, 1970 (3 species) (Acariformes: Chirodiscidae) represented by permanent symbionts of the African shrews of the subfamily Crocidurinae (Soricomorpha: Soricidae) is revised. The external morphology of these species was investigated with light and scanning electron microscopy. Based on the type specimens and newly obtained samples, 2 recognized species, S. scutisorex Fain, 1970 from Scutisorex somereni Thomas and S. kivuensis Fain, 1981 from Crocidura sp.-both are from DR of Congo-are redescribed. A new species S. sylvisorex sp. nov. found on shrews of the genera Sylvisorex (S. granti Thomas (type host), S. lunaris Thomas, S. vulcanorum Hutterer and Verheyen) and Crocidura (C. denti Dollman, C. cf. niobe, Crocidura sp.), collected in the DR Congo is also described. An amended generic diagnosis, including description of female immature stages, and a key to species are provided.

A new species Crocidurobia faini n. sp. (Acariformes: Myobiidae) recorded on Crocidura denti Dollman (type-host) (Soricomorpha: Soricidae), Crocidura cf. niobe Thomas, Crocidura cf. littoralis Heller, and Crocidura sp. from DR Congo is described. This new species differs in both sexes from all other species of the subgenus Crocidurobia Jameson, 1970 by short setae c2, more than three times shorter than setae se. Females of the new species differ from those of the close species Crocidurobia toroensis Dusbabek, 1983 by setal bases e2 situated slightly anterior to the level of setal bases e1; males of the new species differ by the genital shield bearing five pairs of setae situated anterior to the level of setal bases d1.
