Two mite species of the genus Neharpyrhynchus (Acariformes: Harpirhynchidae) were recorded on wild birds in Peru: Neharpyrhynchus trochilinus from Amazilia lacteal, and A. chionogaster (both Apodiformes: Trochilidae) and Neharpyrhynchus tangara from Thraupis episcopus (Passeriformers: Thraupidae). Records from A. chionogaster and T. episcopus represent new hostparasite associations. Mites of this genus were found in Peru for the first time. Dos especies de ácaros del género Neharpyrhynchus (Acariformes: Harpirhynchidae) fueron registrados en aves silvestres del Perú: Neharpyrhynchus trochilinus ex Amazilia lactea y A. chionogaster (ambos Apodiformes: Trochilidae) y Neharpyrhynchus tangara ex Thraupis episcopus (Passeriformes: Thraupidae). Los registros en A. chionogaster y T. episcopus representan nuevas asociaciones huesped - parásito. Los ácaros de este género fueron reportados por primera vez para el Perú.

H. Dubinina (ZISP). Note: the original label says Erinaceus europaeus, however, based on the locality, the host name should be E. roumanicus (Heet al. 2012). Caparinia ictonyctis (Lawrence, 1955) ex Atelerix albiventris: 20 males, 20 females, 10 tritonymphs, 10 protonymphs, and 10 larvae, South Korea, South Leolla Province, Gwangju, pet shop, February 2010, coll.

Lawrence (KZNM 5767); 1 male and 1 female, [original label in French: Ictonyx striatus erythreae, Egypte, Saukin], other data unknown (IRSNB). On the original label by A. Fain, the geographical data are probably not quite correct. Ictonyx striatus erythreae is absent in Egypt but occurs in neighbouring Sudan (Wilson and Reeder 2005). The locality ���Saukin��� is absent in Egypt and according to Geonames database probably is El Qadarif city, 14��02'05''N, 35��23'00''E, Al Qadarif state, Sennar Province, Sudan.

The undetermined ���hedgehog��� from Tanzania recorded as host of this species (Fain 1975) is probably Atelerix albiventris, because among African hedgehogs only this species inhabits Tanzania (He et al., 2012).

Caparinia lophiomys Fain, 1975 12 males and 9 females (paratypes) from Lophiomys imhausi, Somalia, May 1916, no other data (IRSNB). Morphological descriptions. In the analyses, key, and descriptions, the idiosomal chaetotaxy follows Griffiths et al. (1990) with modifications of Norton (1998) for coxal setae. The leg chaetotaxy follows Grandjean (1939). All measurements are given in micrometers (��m) and were taken as follows: body length = total length from the anterior extremity of the palps to the posterior border of the body, including the lobar membranes in males; body width = width at the level of setae cp; length of dorsal shields = maximum length, measured along the median line of the shields; length of male opisthosomal lobes = measured from the anterior edge of the opisthosomal cleft to the posterior end of the lobe; length of the posterior legs = length from the most basal point of the trochanter to the apex of the tarsus, excluding pretarsus. Drawings were made with a Leica microscope equipped with differential interference contrast (Nomarski) optics and a camera lucida. Fine mite structures (mites from Atelerix albiventris, ZISP AVB 14-0505-004) were examined with a scanning electron microscope Quanta 250. Mites were put in 96% ethanol for 24 hours, transferred to hexamethyldisilazane for 10 minutes, and then dried and sputtered with platinum. DNA amplification, sequencing, and alignment. We sequenced individual specimens of Caparinia from Atelerix albiventris and Erinaceus europaeus for 6 genes: two nuclear ribosomal RNA genes, 18S and 28S rDNA; three nuclear protein-coding genes: elongation factor 1alpha100E (EF1-��), signal recognition particle protein 54k (SRP54), Hsc70-5 heat shock protein cognate 5 (HSP70); and one mitochondrial protein-coding gene (CO1). CO1 was sequenced from 14 specimens for Caparinia ex Atelerix albiventris (all were identical) and 2 specimens of Caparinia tripilis ex Erinaceus europaeus. Previously published amplification and sequencing protocols were used (Bochkov et al., 2014; Klimov & OConnor, 2008, 2013; Knowles & Klimov, 2011). GenBank accession numbers are as follows: MG766225 - MG766259, MG766261 - MG766269 (Table 1). The sequence of 18S of Caparinia from Erinaceus europaeus (MG766260) was identified as a gregarine (an endoparasitic protozoan) and, therefore, was excluded from further analyses. Domain D4 of 28S rDNA was also excluded because our standard protocol TABLE 1. Collection data and GenBank accession numbers for select taxa of the scab mite family Psoroptidae (id=unique numbers for DNA extraction vouchers; field number = lot-based museum UMMZ accession numbers for vouchers and co-vouchers). *Gregarine sequence amplified, GenBank accession number MG766260. produced superimposed sequences. Sequences of rDNA were aligned in Mesquite ver. 3.31 (Maddison & Maddison, 2016) using a previously established secondary structure model (Klimov & OConnor, 2008); alignment of other loci was unambiguous. Voucher and co-voucher mite specimens are deposited in the University of Michigan Museum of Zoology, Ann Arbor, Michigan under the following accession numbers: BMOC 13-0508-003 (AD1647): Caparinia ictonyctis, ex Atelerix albiventris; BMOC 16-0825-012 (AD2034), BMOC 16-0825-013 (AD2035): Caparinia tripilis, ex Erinaceus europaeus. Genetic distances. Following tradition, we use Kimura 2-parameter (K2P) genetic distances (Hebert et al., 2003), but see (Srivathsan & Meier, 2012) for criticism. Distances were calculated in PAUP* ver. 4.0a (build 158) (Swofford, 2016) using the default settings., Published as part of Bochkov, Andre V., Klimov, Pavel B., Kim, Da-Hee & Skoracki, Maciej, 2019, Validation of the status of a species with high CO 1 and low nuclear genetic divergences: the scab mite Caparinia ictonyctis stat. res.

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.
