International audience; Mites of the family Chirodiscidae (Acariformes: Sarcoptoidea) are permanent mono- or stenoxenous symbionts of mammals living in the fur of their hosts. Among three genera included in the tribe Schizocarpini (Labidocarpinae), members of the genus Lutrilichus Fain inhabit small carnivores of the families Mustelidae and Viverridae (Carnivora). The external morphology of postembrionic stages of Lutrilichus javanicus Fain, 1970 (Acariformes: Chirodiscidae), collected from Melogale moschata (Gray, 1831) (Mustelidae) in Vietnam, is described. This is the second report of this mite species, previously known from a single female specimen from Melogale orientalis Blanford, 1888 in Java, and the first description of the immature stages in the genus Lutrilichus.

The specific epithet derives from the generic name of the host and is a noun in apposition. Hosts and distribution. This species is known from shrews of the genus Sylvisorex, S. granti (type species), S. lunaris, S. vulcanorum and the genus Crocidura, C. denti, C. cf. niobe, and Crocidura sp. in DR of Congo (present paper). Differential diagnosis. The new species, Soricilichus sylvisorex sp. nov., differs from the two other species of this genus by following features. In both sexes of S. sylvisorex, setae cp are shorter 55 (vs. longer than 70 in both other species); in males, the adanal sclerite is small and without median concavity (vs. large and with deep median concavity). Additionally, this species differs from S. scutisorex by the following character states. In both sexes of S. sylvisorex, setae cp and c 3 are situated off the sclerotized parts of coxal fields III (vs. on these parts in S. scutisorex); in males, the anterior margin of the hysteronotal shield is roughly triangular (vs. almost straight), setae d 1 are situated far anterior from the anterior margin of this shield (vs. almost at level of this margin), the ventrolateral membrane has a triangular posterior edge (vs. with widely rounded edge); in females, setae h 2 are 30–40 long (vs. 9–10 long). Females of S. sylvisorex differ from those of S. kivuensis in having shorter setae h 2 30–40 long (vs. 75–90 in S. kivuensis).

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.

The specific epithet derives from the generic name of the host and is a noun in apposition. Hosts and distribution. This species is known from shrews of the genus Sylvisorex, S. granti (type species), S. lunaris, S. vulcanorum and the genus Crocidura, C. denti, C. cf. niobe, and Crocidura sp. in DR of Congo (present paper). Differential diagnosis. The new species, Soricilichus sylvisorex sp. nov., differs from the two other species of this genus by following features. In both sexes of S. sylvisorex, setae cp are shorter 55 (vs. longer than 70 in both other species); in males, the adanal sclerite is small and without median concavity (vs. large and with deep median concavity). Additionally, this species differs from S. scutisorex by the following character states. In both sexes of S. sylvisorex, setae cp and c 3 are situated off the sclerotized parts of coxal fields III (vs. on these parts in S. scutisorex); in males, the anterior margin of the hysteronotal shield is roughly triangular (vs. almost straight), setae d 1 are situated far anterior from the anterior margin of this shield (vs. almost at level of this margin), the ventrolateral membrane has a triangular posterior edge (vs. with widely rounded edge); in females, setae h 2 are 30���40 long (vs. 9���10 long). Females of S. sylvisorex differ from those of S. kivuensis in having shorter setae h 2 30���40 long (vs. 75���90 in S. kivuensis)., Published as part of Bochkov, Andre V., Mbalitini, Sylvestre G. & Verheyen, Erik, 2016, Review of the fur-mite genus Soricilichus Fain, 1970 (Acariformes: Chirodiscidae) ��� symbionts of the African shrews of the subfamily Crocidurinae (Soricomorpha: Soricidae), pp. 235-253 in Zootaxa 4072 (2) on pages 249-252, DOI: 10.11646/zootaxa.4072.2.6, http://zenodo.org/record/270676

The present study reports the occurrence of Parakosa flexipes (Pinichpongse) (Chirodiscidae) for the first time in Brazil, along with its infection sites on Molossus rufus E. Geoffroy. Thirty-eight bats were caught using mist nets that were placed near a house at the Mars Center for Cocoa Science in the state of Bahia, of which 14 (37%) were parasitized by P. flexipes. Parakosa flexipes was observed parasitizing M. rufus on hairs that were evidently longer than others distributed over the bat's body, where up to three parasites could be spotted on a single hair.

Two genera of Labidocarpine mites (Afrolabidocarpus Fain, 1970 and Asiolabidocarpus Fain, 1972) parasitic on East Asiatic bats are revised and 2 new species described: Afrolabidocarpus longipes n. sp. and A. vietnamensis n. sp.

The genus Parakosa McDaniel & Lawrence, 1962 is represented in the East Asiatic bats by 4 species. These species are redescribed here and depicted for the first time. A key to the genus is given.

The oriental species of the genera Olabidocarpus Lawrence, 1948, Dentocarpus Dusbabek & Cruz, 1966, Labidocarpellus Fain, 1976 and Pteropiella Fain, 1970 are revised. The species are redescribed and depicted except for a few which have been fully described recently. The total number of species known from these genera in this region is now 17. Labidocarpellus papuanus Fain, 1975 is replaced in the genus Pteropiella. The subgenus Dentocarpus (Paradentocarpus) Fain, 1976 is placed in synonymy with Labidocarpellus and the three species described in this subgenus (D. (P.) abyssinicus Fain, 1976, D. (P.) phyllodermae Fain, 1976, and D. (P.) kimberleyensis Fain & Lukoschus, 1981) are transferred to Labidocarpellus. Labidocarpellus notopteris Fain, 1976 and L. novaeguineae Fain, 1976 are now transferred to Dentocarpus. Olabidocarpus peropteryx Fain, 1972 and O. guyanensis Fain, 1972 are transferred to Labidocarpellus. A key is given to all the genera of Chirodiscidae parasitic on bats. ac]19820102

A collection of listrophoroid mites (Listrophoroidea) belonging to the Bishop Museum, Honolulu, and collected from mammals in New Guinea was studied. This collection contains 23 species and 2 subspecies, of which 2 species are described as new. Complete descriptions and illustrations are provided for 9 species and 2 subspecies briefly described in a preliminary note by Fain (1975). The species treated belong to 7 genera, 6 in the family Atopomelidae and 1 in the Chirodiscidae. This report brings the total number of species of Listrophoroidea known from New Guinea to 43 and the number of genera to 13, all belonging to the Atopomelidae and Chirodiscidae.

Four genera of Labidocarpinae (Listrophoroidea, Chirodiscidae), parasitic on oriental bats are revised: Paralabidocarpus Pinichpongse, 1963, Labidocarpoides Fain, 1970, Labidocarpus Trouessart, 1895 and Alabidocarpus Ewing, 1929. These genera are represented in oriental bats by 28 species of which five are new. These mites live attached to the hairs of their host (fur-mites). They are low grade pathogens and are generally well tolerated by their hosts. The holotypes of all these species, except that of Alabidocarpus fujii Wada which was not available, have been examined.

Four species of Labidocarpine bat-mites, Parakosa tadarida, McDaniel and Lawrence, Pseudolabidocarpus secus McDaniel, Lawrenceocarpus lobus McDaniel and Paralabidocarpus artibei Pinichpongse are recorded from the Caribbean Islands of Jamaica (Greater Antilles) and Guadeloupe (Lesser Antilles).

The male of Olabidocarpus amencanus is described from the Hawaiian Hoary Bat, Lasiurus cinereus semotus . The female is reillustrated from Hawaiian material.
