A. Fain. Type deposition. Holotype is deposited in IRSNB. Host range and distribution. This species was originally collected from Rhinolophus hipposideros (type host) from Belgium and initially determined as O. zumpti (Fain 1959a). Later, Fain (1967) described O. striatus based on these specimens and also recorded the species from Rhinolophus deckenii Peters from Tanzania and Asellia tridens (Geoffroy) (Hipposideridae) from Libya. The records of O. zumpti from Rhinolophus ferrumequinum from Belgium (Fain 1959a) and Ukraine (Zabludovskaya 2005) could possibly refer to P. striatus. We examined only specimens from the type host; other records should be reconfirmed.

E. Suazo (ESG 063). Type deposition. Holotype and paratype are deposited in UMSM. Host range and distribution. This species is known from the type host Saccopteryx bilineata from Peru (our data). Remarks. This new species differs from all known representatives of the genus Rodhainyssus in both sexes by the long sword-like posterior projections of the gnathosoma. In all other species these projections are widely rounded apically or are short. The new species is close to R. balantiopteryx and R. emballonurae. In all three species, setae c2 are absent, the sternum is not connected with apodemes II, apodemes III are fused to each other, and the posterior apodemes of coxal fields II are not connected with apodemes II. It differs from R. balantiopteryx in both sexes by the presence of setae si and by the absence of setae f2; in females by the presence of the punctate area between setae h2 and h3; in males by the presence of the median opisthogastric plate (fused adanal shields), and by setae 4b situated posterior to the pregenital apodeme. In both sexes of R. balantiopteryx setae si are absent, and setae f2 are present; in females the area between setae h2 and h3 are smooth; in males the median opisthogastric plate is absent, and setae 4b are situated on the pregenital apodeme. Males of R. saccopteryx sp. nov. differ from R. emballonurae by the arch-like shape of the median opisthogastric plate, bearing setae h3 and ps3, the absence of the ventral folds on trochanters I and II, and by the posterior end of the aedeagus situated distinctly posterior to setae g. In males of R. emballonurae the median opisthogastric shield has irregular margins and bears only setae ps3, its shape is close to ovoid in outline, the ventral folds of trochanters I and II are present, and the posterior end of the aedeagus is situated at the level of setae g., Published as part of Bochkov, Andre V., Zabludovskaya, Svetlana & Oconnor, Barry M., 2008, Phylogeny and systematics of the endoparasitic astigmatid mites (Acari: Sarcoptiformes) of mammals: families Gastronyssidae, Lemurnyssidae, and Pneumocoptidae, pp. 1-152 in Zootaxa 1951 (1) on pages 62-64, DOI: 10.11646/zootaxa.1951.1.1, http://zenodo.org/record/5240616

Holotype and part of paratypes are deposited in FMNH, other paratypes in USNM and UMMZ. Host range and distribution. This species is known only from the type host (Rattus rattus) from Madagascar, where the host was introduced by human activity. We have flushed nasal passages of numerous specimens of R. rattus from the African mainland, and those of other Rattus species from Asia without recovering this species. Since we have not recovered Yunkeracarus mites from any native rodent species in Madagascar, it seems likely this species will ultimately be recovered from R. rattus in other parts of its range. Etymology. The species name is derived from the generic name of the host and is a noun in apposition. Remarks. This new species is very close to Y. apomys. In both of these species setae cG I are microspines, setae si are distinctly (1.5–2 times) shorter than se and situated close to each other, distance si–si is 5–6 times shorter than se–se, setae c3 is about two times shorter than cp; in females, the bursa copulatrix opens dorsally; in males the posterior end of the aedeagus is situated at the level of setae 4a. It differs from Y. apomys by the following characters. In females of Y. rattus, the length of the body, including the gnathosoma, is 350–365, setae 1a are 13–16 long, setae c3 are 18–22 long, setae cp are 2.3–2.7 times longer than c3, the posterior projections of coxal fields I are about 2.1 times wider than long; in males, the length of the body, including the gnathosoma, is 310–335. In females of Y. apomys, the length of the body, including the gnathosoma, is 370– 390, setae 1a are 9–13 long, setae c3 are 11–16 long, setae cp are 1.9–2.3 times longer than c3, the posterior projections of coxal fields I are about 1.4 times wider than long; in males, the length of the body, including the gnathosoma, is 360., Published as part of Bochkov, Andre V., Zabludovskaya, Svetlana & Oconnor, Barry M., 2008, Phylogeny and systematics of the endoparasitic astigmatid mites (Acari: Sarcoptiformes) of mammals: families Gastronyssidae, Lemurnyssidae, and Pneumocoptidae, pp. 1-152 in Zootaxa 1951 (1) on pages 107-108, DOI: 10.11646/zootaxa.1951.1.1, http://zenodo.org/record/5240616

S.M. Goodman (SMG 3868). Host range and distribution. This species is known from mice of the genus Apodemus, A. sylvaticus (type host) from Europe (Belgium and the Netherlands), Ukraine (Zabludovskaya 1990), A. agrarius (Pallas) from South Korea (Fain et al. 1967), and A. wardi from Pakistan. The records of solitary specimens from Mus musculus L. (Muridae) and Microtus socialis (Pallas) (Cricetidae) from Ukraine (Zabludovskaya 1990) need additional confirmation. Remarks. Y. apodemi was described as a subspecies Y. faini (Fain et al., 1967). It clearly deserves species status because it differs from Y. faini by several consistent characters. The most notable features of this species are the short distance between setae si–si, 7–11 and the bursa copulatrix opens terminally. In Y. faini the distance si–si is about 18, and the bursa copulatrix opens dorsally., Published as part of Bochkov, Andre V., Zabludovskaya, Svetlana & Oconnor, Barry M., 2008, Phylogeny and systematics of the endoparasitic astigmatid mites (Acari: Sarcoptiformes) of mammals: families Gastronyssidae, Lemurnyssidae, and Pneumocoptidae, pp. 1-152 in Zootaxa 1951 (1) on pages 110-111, DOI: 10.11646/zootaxa.1951.1.1, http://zenodo.org/record/5240616, {"references":["Fain, A., Lukoschus, F.

Lukoschus. Type deposition. Holotype is deposited in RMNH. Host range and distribution. This species is known from the type host only, E. sp. (fuscus or brasiliensis) from Suriname (Fain & Lukoschus 1972). Remarks. The host species of R. surinamensis, Eptesicus “ melanopterus ” was listed by Fain and Lukoschus (1972) without an author. This species name, however, is not in current use. There are two homonymous epithets “ melanopterus ” both of which are currently considered as junior synonyms of other Eptesicus species, Eptesicus melanopterus Rehn = junior synonym of E. fuscus (Beauvois) and Eptesicus melanopterus Jentink = junior synonym of E. brasiliensis (Desmarest). Since both of these species occur in Suriname, it is impossible to know which Eptesicus species is the type host for R. surinamensis., Published as part of Bochkov, Andre V., Zabludovskaya, Svetlana & Oconnor, Barry M., 2008, Phylogeny and systematics of the endoparasitic astigmatid mites (Acari: Sarcoptiformes) of mammals: families Gastronyssidae, Lemurnyssidae, and Pneumocoptidae, pp. 1-152 in Zootaxa 1951 (1) on pages 53-55, DOI: 10.11646/zootaxa.1951.1.1, http://zenodo.org/record/5240616, {"references":["Fain, A. & Lukoschus, F.

R.M. Timm (RMT 3724). Host range and distribution. This species is known from Peromyscus leucopus from USA (Michigan and New York) (Hyland & Clark 1959; our data) and Peromyscus mexicanus from Costa Rica (new host). Remarks. Y. faini has been described from three female and one?nymphal specimens (Hyland & Clark 1959). According to the original description and our observations, the female holotype and a single collected male of Y. faini from the type host bear microspines cG I. Fain et al. (1967), who examined the two remaining paratypes, reported filiform setae cG I in these specimens. We also observed filiform setae cG I in a single female from the type host (see material). Unfortunately we were not able to examine female paratypes of this species because their present depository is unknown and they are probably lost. Thus, it is still unclear whether the holotype is an aberrant specimen, the shape of setae cG I is sexually dimorphic, or in females of Y. faini the shape of this seta is variable. Specimens from Peromyscus mexicanus differ slightly from mites from the type host by smaller sizes (see descriptions) and the length ratio of cp/c3 setae (1.3:1 vs. 1.7–1.8: 1 in specimens from Peromyscus leucopus). Additional collections from these hosts are necessary to clarify the status of specimens from P. mexicanus., Published as part of Bochkov, Andre V., Zabludovskaya, Svetlana & Oconnor, Barry M., 2008, Phylogeny and systematics of the endoparasitic astigmatid mites (Acari: Sarcoptiformes) of mammals: families Gastronyssidae, Lemurnyssidae, and Pneumocoptidae, pp. 1-152 in Zootaxa 1951 (1) on pages 126-127, DOI: 10.11646/zootaxa.1951.1.1, http://zenodo.org/record/5240616, {"references":["Hyland, K.
