“…Arnold et al [44] argue that, compared to their congeners, Micronycteris hirsuta has undergone extensive and independent karyotypic changes, which has been supported by other authors [3,12,13]. Our results corroborate the hypothesis of karyotypic megaevolution within Micronycteris , and strong evidence for this is that the entire chromosome complement of M. hirsuta proved to be derivative with respect to species compared in this study.…”

BackgroundThe genus Micronycteris is a diverse group of phyllostomid bats currently comprising 11 species, with diploid number (2n) ranging from 26 to 40 chromosomes. The karyotypic relationships within Micronycteris and between Micronycteris and other phyllostomids remain poorly understood. The karyotype of Micronycteris hirsuta is of particular interest: three different diploid numbers were reported for this species in South and Central Americas with 2n = 26, 28 and 30 chromosomes. Although current evidence suggests some geographic differentiation among populations of M. hirsuta based on chromosomal, morphological, and nuclear and mitochondrial DNA markers, the recognition of new species or subspecies has been avoided due to the need for additional data, mainly chromosomal data.ResultsWe describe two new cytotypes for Micronycteris hirsuta (MHI) (2n = 26 and 25, NF = 32), whose differences in diploid number are interpreted as the products of Robertsonian rearrangements. C-banding revealed a small amount of constitutive heterochromatin at the centromere and the NOR was located in the interstitial portion of the short arm of a second pair, confirmed by FISH. Telomeric probes hybridized to the centromeric regions and weakly to telomeric regions of most chromosomes. The G-banding analysis and chromosome painting with whole chromosome probes from Carollia brevicauda (CBR) and Phyllostomus hastatus (PHA) enabled the establishment of genome-wide homologies between MHI, CBR and PHA.ConclusionsThe karyotypes of Brazilian specimens of Micronycteris hirsuta described here are new to Micronycteris and reinforce that M. hirsuta does not represent a monotypic taxon. Our results corroborate the hypothesis of karyotypic megaevolution within Micronycteris, and strong evidence for this is that the entire chromosome complement of M. hirsuta was shown to be derivative with respect to species compared in this study.

“…), though it is unlikely, in view of the quite distinct ways that T. schulzi and T. bidens albumins are viewed by each of the antisera, that this karyotypic character is synapomorphic for the two. Electrophoretic data also show T. bidens and T. schulzi as highly divergent as they share no derived alleles either with each other or with any other Tonatia species (Arnold et al, 1983). Nonetheless, in light of the strong morphological similarities betwen T. bidens and other Tonatia species (Genoways and Williams, 1984;Goodwin, 1942), we still think it best to refrain from overinterpreting these results, though we do think it quite likely that future studies will support the phylogenetic placements derived here.…”

Albumin immunology is used both to determine species relationships within the bat genera Micronycteris, Phyllostomus, and Tonatia, and to evaluate whether or not these genera are monophyletic. Species of Tonatia are immunologically very divergent and represent several distinct lineages. The albumin data cannot confirm the monophyly of this genus. Tonatia bidens is divergent chromosomally, electrophoretically, and immunologically, and the albumins suggest that this species is as divergent from other species of Tonatia as it is from Phyllostomus. Phyllostomus is monophyletic with Phylloderma fitting well within the Phyllostomus clade. Although Micronycteris is monophyletic, the genus consists of several lineages which may represent ancient divergences. The degree of divergence among Micronycteris species plus the fact that Micronycteris albumins have changed little with respect to other phyllostomid genera makes the determination of species relationships difficult.The subfamily Phyllostominae consists of 11 genera of New World leaf-nosed bats. Comparisons of these 11 genera with representatives of the other five subfamilies suggest that the Phyllostominae is paraphyletic. Chromosomal (Patton and Baker, 1978; R. J. Baker, pers. comm.), morphological (Hood and Smith, 1982), and immunological data (Honeycutt, 1981) indicate at least two groups of phyllostomine genera. The subfamilies Carolliinae, Stenoderminae, Glossophaginae, and Brachyphyllinae associate with one phyllostomine clade (Phyllostomus/Tonatia) which contains Lonchorhina, Macrophyllum, Mimon, and Phylloderma, and the genera Chrotopterus, Macrotus, Micronycteris, Trachops, and Vampyrum represent another distinct group of phyllostomines. Although the immunological data provide a clear association among Chrotopterus, Trachops, and Vampyrum with Macrotus and Micronycteris representing distinct and divergent lineages, the chromosomal and morphological data are less equivocal.Unlike most phyllostomine genera which consist of only one or two species, Micronycteris, Phyllostomus, and Tonatia each have several species. Micronycteris and Tonatia species can be markedly divergent from one another both chromosomally (Patton and Baker, 1978) and electrophoretically (Arnold et aI., 1983), and certain species have undergone "karyotypic megaevolution" to such a degree that obvious congeneric chromosomal homologies are lacking (Baker and Bickham, 1980). In addition, at least two species of Tonatia do not associate with their congeners electrophoretically. Phyllostomus species and Phylloderma are quite similar to one another chromosomally (Patton and Baker, 1978), but few, if any, data bearing on interspecific relationships exist.In light of the existing information on species relationships within Tonatia, Micronycteris, and Phyllostomus, the question as to whether or not these genera are monophyletic needs to be addressed. We have used albumin immunology to test for monophyly and our results as to phylogenetic relationships are compared to those suggested by other data. M...

“…Interestingly enough, the two new Periglischrus species, although belonging to the different phenetic branches acutisternus and torrealbai, are found on two species of the same large group of Tonatia. The morphological differences in these mites support that the size-based arrangement of Tonatia does not correspond to a natural group, as an allozyme-based study has suggested (Arnold et al 1993). In fact, small and large bat species share external and cranial characters: e.g., T. silvicola (large) and T. brasiliense (small) show a similar marked postorbital constriction.…”

Two new species of spinturnicid mites of the genus Periglischrus are described and illustrated from phyllostomid bats from southeastern Mexico: The female, male, and protonymph of Periglischrus steresotrichus, new species, from Tonatia evotis Davis & Carter, and the female and male of Periglischrus eurysternus, new species, from Tonatia saurophila Koopman & Williams. A supplementary description of the male deutonymph of P. eurysternus from T. saurophila from Panama is given. The morphological features of the two new species of Periglischrus are used as a basis for discussing their phylogeny and its potential relationship to that of their hosts.
