A new species of Eudusbabekia (Acari: Prostigmata: Myobiidae) from Hart's little fruit bat, Enchistenes hartii (Chiroptera: Phyllostomidae), in southern Mexico

Eudusbabekia paralepidoseta new species, was recorded on the Hart's little fruit bat Enchistenes hartii (Thomas) in the southern part of Mexico. The female and male are described and illustrated. E. paralepidoseta n. sp. represents the 32nd species in the genus. From the 31 known species of Eudusbabekia known to infest phyllostomid and mormoopid bats, E. paralepidoseta n. sp. has some morphological features similar to Eudusbabekia lepidoseta Jameson, 1971, including shapes of almost all dorsal and ventral setae; the presence of a patch of supernumerary; mostly broad to thick, medium, and almost scale-like setae; and the absence of setae 2b. However, E. paralepidoseta n. sp. can be differentiated from E. lepidoseta, by the reduced number of supernumerary setae on the female venter (37-43). The close morphological and therefore evolutionary similarities between E. lepidoseta and E. paralepidoseta n. sp. suggest possible close evolutionary relationships between their hosts, Sturnira lilium (Geoffroyi and St.-Hilaire) and E. hartii, which belong to the monophyletic subfamily Stenodermatinae.

A review of the European Harpirhynchidae (Acari, Prostigmata) with the description of a new species

Records of the European Harpirhynchidae Dubinin, 1957 (Acari, Prostigmata) are summarized and briefly discussed. This family is represented in Europe by 23 species belonging to three subfamilies, Harpirhynchinae (18 species recorded), Harpypalpinae Fain, 1972 (4 species recorded), and Ophioptinae Southcott, 1956 (1 species recorded). A new species Harpirhynchus dusbabeki sp. nov. from the bearded tit Panurus biarmicus (L., 1758) (Passeriformes, Timaliidae) in Slovakia is described. This new species differs morphologically from the two similar congeneric species, H. nidulans Nitzsch, 1818 and H. galeridae Fain, Bochkov et Mironov, 1999, by having setae 3a and two setae on both genua I and II.     

The genus Parasecia (Acari: Trombiculidae), with the description of a new species from Mexico.

The genus Parasecia Loomis, 1966, is redefined, and Parasecia bulbocalcar Goff is described as new from specimens collected off a Yellow-shouldered Bat, Sturnia ludovici Anthony, taken in Morelos, Mexico. A key to the 15 species of Parasecia is provided.     

Revision of the genus Andreacarus (Acari: Laelapidae) with description of seven new species and a new genus for Australian species formerly placed in Andreacarus

The mesostigmatid genus Andreacarus Radford, 1953 (Acari: Laelapidae), species of which are obligatory parasites of small mammals, is revised. Andreacarus includes 11 species, four species previously recognized and seven new species described from Madagascar hosts: A. brachyuromys sp. n. from Brachyuromys betsileoensis Bartlett, A. eliurus sp. n. from Eliurus species, A. gymnuromys sp. n. from Gymnuromys roberti Major, A. voalavo sp. n. from Voalavo gymnocaudus Carleton & Goodman, A. nesomys sp. n. from Nesomys rufus Peters-all from nesomyid rodents; A. tenrec sp. n. from Tenrec ecaudatus Schreber (Afrosoricida: Tenrecidae); and A. galidia from Galidia elegans I. Geoffroy Saint-Hilaire (Carnivora: Viverridae). An amended generic diagnosis and key to females are also given. Six species described in Andreacarus from Australian and New Guinean hosts are removed and transferred to the new genus, Juxtalaelaps.     

A new genus and species of pterodectine feather mite (Acari: Proctophyllodidae) from Tod-Tyrants in Brazil (Passeriformes: Tyrannidae)

A new genus and species of feather mite, Hemitriccodectes furcatus gen. nov., sp. nov., is described from passerines of the genus Hemitriccus from Brazil: Hemitriccus furcatus, H. margaritaceiventer and H. striaticollis (Tyrannidae). The new genus belongs to the Pterodectes generic complex and most clearly differs from previously established genera of this complex by the following combination of features: trochanteral setae sRIII are present, and solenidia σ are absent from genua III. The new genus also lacks dorsal hysteroromal setae c1.     

ZOO-FISH Analysis in a Species of the Order Chiroptera: Glossophaga soricina (Phyllostomidae)

Glossophaga soricina is a flower-visiting bat which lives in the neotropics. The diploid chromosome number is 2n = 32 with a fundamental number of autosomal arms, FN, of 60. G. soricina belongs to the Microchiroptera which have a lower diploid DNA content and a higher AT composition in their DNA compared with other mammals. By ZOO-FISH analysis with human chromosome-specific DNA probes, the human autosomes were found conserved in 41 segments. This is an arrangement similar to other mammals which have been analyzed. Several chromosomal associations already known from ZOO-FISH studies in other species were also present in G. soricina. This revised version was published online in August 2006 with corrections to the Cover Date.     

Light Microscopic and Ultrastructural Observations on the Vomeronasal Organ of Anoura (Chiroptera: Phyllostomidae)

The vomeronasal organ (VNO) is known to be present in bats of the family Phyllostomidae, but in most species this is inferred from the presence of accessory olfactory bulbs. Like primates, bats have profound intergroup variations in the vomeronasal system. Of the family Phyllostomidae (49 genera, 143 species) the VNO of approximately 60 species has been studied. Here, we report light microscopic observations of the VNO of Anoura geoffroyi (fetus and adult), A. caudifer, and A. cultrata, as well as ultrastructural observations of the VNO in adult A. geoffroyi. The organ is crescent‐shaped, with a wide lumen encroached by a “mushroom body” that contains a venous sinus. In adults, the vomeronasal cartilage is reduced, being longer in absolute length in fetal A. geoffroyi compared with the adult. In the neuroepithelium, the receptor cell microvilli are dark, distinct, and short, emerging from a vesicular tuft; the supporting cell microvilli are relatively much longer. Large paravomeronasal ganglia are observed. The receptor‐free epithelium is undulating and lacks cilia or microvilli. Some characteristics of the VNO in Anoura have not been reported in other chiropterans to date, such as the marked reduction of the vomeronasal cartilage and absence of cilia in the receptor‐free epithelium. Moreover, if A. geoffroyi is representative, the genus has an adult neuroepithelial volume similar to other mammals of its body size. Further examination of uninvestigated phyllostomid VNOs may elucidate a phylogenetic history of the family, as well as ecological or social correlates of the VNO in the order Chiroptera.

Acarine infracommunities associated with the Mexican free-tailed bat, Tadarida brasiliensis mexicana (Chiroptera: Molossidae) in arid regions of Mexico

The Mexican free-tailed bat, Tadarida brasiliensis mexicana, is one of the most widely distributed bats, and its range includes the whole Mexican territory. Ectoparasites of this bat have been the subject of isolated reports, but no studies of its community ecology have been conducted. The acarine infracommunities associated with this bat were analyzed, comparing bat populations from three arid regions of Mexico: an abandoned factory in Nombre de Dios, Durango; a cave in Santiago, Nuevo León; and a church in Concepción del Oro, Zacatecas. The acarine infracommunity in Nuevo Le6n's bats exhibited the highest levels of diversity as reflected by a higher richness, a lower dominance, and a moderate and relatively homogeneous abundance in this locality in relation to the other two. This pattern is influenced by stable cave conditions relative to artificial habitats. Notwithstanding, further studies are required to determine whether or not different habitat conditions are a primary factor in the process of structuring the acari infracommunities.     

Morphology and Postnatal Development of Lower Hindlimbs in Desmodus rotundus (Chiroptera: Phyllostomidae): A Comparative Study

The hindlimbs in bats are functionally adapted to serve as a hook to attach to the mother from birth, and to roost during independent life. Although bats exhibit different terrestrial locomotion capabilities involving hindlimbs, hindlimb morphology and postnatal development have been poorly studied. We describe in detail the postnatal development and bone morphology of hindlimbs of the nimble walker vampire bat, Desmodus rotundus, and compare adult characters with the insectivorous Molossus molossus (erratic walker) and the frugivorous Artibeus lituratus (non‐walker). The advanced ossification of most hindlimb elements of D. rotundus at the newborn stage is consistent with the functional role of this structure at birth in bats. The development completion events of hindlimb bone elements and bone processes in D. rotundus coincide with the cranial bone processes completion and suture closure events. Those events occur when individuals begin to feed by themselves. There are differences in the number and position of bone processes and sesamoids in adults among the compared species, most of which are described for the first time, and in the case of D. rotundus and M. molossus mostly related to a greater and tight articulation between elements. These facts seem to be closely associated with the different terrestrial locomotion capabilities, and in the case of the exclusively sanguivorous D. rotundus with specializations for obtaining food.
