437687C1E62EFFB7FF4CCB84FBBEFDB2.taxon	discussion	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.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

437687C1E627FFBEFF4CCB14FA6FFC82.taxon	discussion	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 c 2 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 f 2; in females by the presence of the punctate area between setae h 2 and h 3; in males by the presence of the median opisthogastric plate (fused adanal shields), and by setae 4 b situated posterior to the pregenital apodeme. In both sexes of R. balantiopteryx setae si are absent, and setae f 2 are present; in females the area between setae h 2 and h 3 are smooth; in males the median opisthogastric plate is absent, and setae 4 b 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 h 3 and ps 3, 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 ps 3, 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.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

The record from Macroglossus minimus (Geoffroy) (= lagochilus) (Pteropodidae) from Indonesia (Fain 1959 a) probably refers to Opsonyssus pseudoindicus sp. nov.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

437687C1E659FFC4FF4CC9CBFDA9FD9A.taxon	discussion	Remarks. This subspecies was elevated to species rank by Fain (1967). The characters differentiating O. indicus from O. brutsaerti reported by Fain (1959 a), the shape of the posterior projections of the gnathosoma, the shape of the sternal lobes, and the shape of the sclerotized area at the site of fusion of apodemes II and the sternum, overlap in O. brutsaerti and O. indicus. We have not been able to morphologically separate these two forms since only a few females of O. indicus have been collected. On the other hand, these two forms are geographically isolated from each other and parasitize different hosts, suggesting the lack of gene exchange between them. Therefore we consider O. indicus as a geographical subspecies of O. brutsaerti until new material can clarify the status of O. indicus.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

437687C1E670FFEAFF4CC9CBFE76FB32.taxon	biology_ecology	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.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

437687C1E663FFFAFF4CCCD3FA68FE7A.taxon	discussion	Remarks. According to the diagnosis of Zabludovskaya (1989, 1990), Y. stepposus differs from Y. ascanicus, known only from two females, by the weakly sclerotized idiosoma and legs, short sternum, the presence on tarsi I – III of three and two claw like setae, respectively, and by some measurements. Actually, the two female specimens of Y. ascanicus are teneral and therefore, weakly sclerotized. The sternal length in Y. ascanicus does not differ from that of Y. stepposus being 19 – 20 long, but the posterior half of the sternum in these specimens is indistinct due to weak sclerotization. The comparative examination of tarsal setation did not reveal any distinctions between these two species. The measurements of Y. ascanicus and Y. stepposus are completely compatible (see descriptions). Therefore we consider Y. stepposus as a junior synonym of Y. ascanicus, syn. nov. Our comparison of type specimens of Y. microti and Y. ascanicus shows their similarity. The measurements of these two species are overlapping or almost overlapping, and distinctions in qualitative characters are not observable. A difference in the position of setae cG II was mentioned by Zabludovskaya (1990). According to Smith et al. (1985: 482, fig. 1) setae cG II are situated in the basal part of the segment in Y. microti, whereas in Y. ascanicus (= Y. stepposus) these setae are situated in the median part of genu II (Zabludovskaya 1990). Based on our observations, in Y. microti setae mG II are also situated in the median part of the segment, but the seta is visible only if legs II of the observed specimen are extended. In mounted mites these legs are quite often bent and, therefore, setae mG II seem to be positioned at the genual base. The only difference between Y. ascanicus and Y. microti is some disparity in the length ratio of setae c 3 and cp. In Y. microti from Microtus pennsylvanicus (USA), setae c 3 are subequal to cp or up to 1.1 – 1.3 times longer than these setae (1.5 times longer in Belgian specimens from Microtus arvalis), whereas in Y. ascanicus setae c 3 are 1.6 – 1.8 times longer than cp. We suppose that additional sampling of mites from different species of Microtus from different localities could help to clarify whether Y. ascanicus and Y. microti are actually separate species.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

437687C1E667FFFFFF4CCCC9FA81FC82.taxon	discussion	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 / c 3 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.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.

This species was described from the lungs of Spermophilus beecheyi (Richardson) (Sciuridae) from California, USA.	en	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.

437687C1E68EFF15FF4CC833FB14F841.taxon	discussion	Remarks. This species was described and illustrated in a rudimentary manner that does not allow for specific recognition. The original type material is presumed lost. Baker (1951) mentioned this species but retained it in the family Cytoditidae. Lee and Dutson (1971) reported this species from the lungs of 8 from 79 individuals of S. beecheyi examined at two localities in northern California. They transferred the species to the genus Pneumocoptes and described the pathological reaction to the mites in the alveoli of the lungs. Unfortunately, no additional morphological description was provided nor were voucher specimens deposited. Until new specimens can be collected and studied in detail, this species must remain incertae sedis.	en	Bochkov, Andre V., Zabludovskaya, Svetlana, Oconnor, Barry M.
