“…Concerning Hipposideros cf ruber, our Nimba specimen has the same standard formula as documented by Koubínová et al (2010), who reported on seven females from Senegal, 2n = 32, NFa = 60. The autosomes of this species included four pairs of metacentric, eight pairs of submetacentric and three pairs of subtelocentic (considered here as submetacentric).…”

“…The standard karyotype of H. ruber is also identical to H. tephrus and H. jonesi but it is different from the karyotype of H. cyclops (2n = 36, NFa = 62) and H. gigas (2n = 52, NFa = 60). The large variation in diploid number (2n) and the similar fundamental numbers of chromosomal arms (NFa) indicate that the Robertsonian rearrangements are a probable source of karyotype variation among these species (Koubínová et al 2010). Porter et al (2010) noted that one specimen of H. caffer from Gabon had a 2n = 32 (NFa not indicated) karyotype similar to most other congeneric species with 2n = 32.…”

New bats were recorded from various habitats on the Guinean side of Mount Nimba during two surveys in 2008 and coupled with a cytotaxonomic survey. A total of 152 specimens comprising 15 species in 12 genera from five families were collected, of which 13 individuals were karyotyped. The most numerous species was Rhinolophus guineensis followed by four fruit bats (Epomops buettikoferi, Lissonycteris angolensis, Roussettus aegyptiacus, Nanonycteris veldkampii). We confirm the presence of Hipposideros lamottei in the mine adits at 1500 m as well as the exceptional diversity of this habitat. First standard karyotypes are provided for Epomops buettikoferi and Nanonycteris intermedia. We also document for the first time karyotypes for West African populations of Mops thersites, Lissonycteris angolensis and Roussettus aegyptiacus, and cytogenetical comparisons with the existing literature are provided. We add five new species to the list of Guinean Nimba and two to the whole Nimba list (including Liberian side), which now stands at 42 species. This confirms the importance of Mount Nimba as a hotspot of diversity and the necessity to protect it.

“…Different karyotypes were found in H. obscurus (2n=24), H. cyclops (2n=36), H. commersoni (2n=52) and H. gigas (2n=52) (Koubínová et al 2010). Robertsonian mechanisms of centric fusion/fission combined possibly with whole arm translocations have played a major role in the karyotypic evolution within the genus Rhinolophus (Mao et al 2007) and similar mechanisms but with the opposite direction can also be proposed for the genus Hipposideros (Sreepada et al 1993, Koubínová et al 2010. The similar fundamental numbers (number of chromosome arms) found in individual karyotypes indicate that the Robertsonian rearrangements are the probable source of karyotype variation among the species of the family Hipposideridae.…”

“…Within the genus Hipposideros, exceptions from this uniform pattern were found in H. commersoni from South Africa (Rautenbach et al 1993) and in H. obscurus from the Philippines (Rickart et al 1999). The karyotype of H. commersoni had 2n=52, whereas that of H. obscurus had 2n=24 (NFa=44) (Koubínová et al 2010).…”

Chromosome Analysis and Morphometric of Intermediate Roundleaf Bat, Hipposideros larvatus (Chiroptera, Hipposideridae) by Conventional, GTG-banding and Ag-NOR Banding Techniques

et al. 2014

Summary Chromosome analysis and morphometrics of the intermediate roundleaf bat (Hipposideros larvatus) from Northeast Thailand were studied. Bat chromosome preparations were conducted by squash technique from bone marrow and testis. Conventional staining, GTG-banding and Ag-NOR banding techniques were applied to stain the chromosomes. The results showed that the diploid chromosome number of H. larvatus was 2n=32, and the fundamental number (NF) was 66 in both males and females. The types of autosomes observed were 14 large metacentric, 2 large submetacentric, 4 medium metacentric, 4 medium submetacentric, 2 small metacentric, 2 small submetacentric, and 2 small telocentric chromosomes. The X-chromosome was a large submetacentric chromosome and the Y-chromosome was a small submetacentric chromosome. From the GTG-banding technique, the number of bands in H. larvatus was 159, and the location of each chromosome pair could be clearly differentiated. NORs are located at the secondary constriction near the centromere on the long arm of the large metacentric chromosome pair 8. We found that during metaphase I the homologous chromosomes showed synapsis, which can be defined as the 16 bivalents. Six external morphological characters were measured as well as 13 cranial and dental measurements. The karyotype formula of H. larvatus was as follows:2n (44)

How many species ofHipposideroshave occurred on Madagascar since the Late Pleistocene?

Populations of the Malagasy Hipposideros commersoni (family Hipposideridae) are threatened by deforestation and hunting. Maximum likelihood and Bayesian analysis of 148 cytochrome b sequences found this species to be paraphyletic and composed of three well-supported monophyletic clades. Clades B and C form a monophyletic lineage that can be referred to H. commersoni; these two clades are separated by 6% sequence variation. Clade A represents a distinct evolutionary lineage separate (9-11% average sequence divergence) from H. commersoni (clades B and C) and is named herein as a new species, Hipposideros cryptovalorona sp. nov. In the phylogeny presented herein, this species is strongly associated with the outgroup taxa Hipposideros gigas and Hipposideros vittatus, both restricted to Africa. External, cranial and dental measurements taken from the same individuals used in the molecular study indicate no clear distinction in morphology amongst these three clades; this includes noseleaf structure and craniodental characteristics. Principal component analyses showed limited separation of the three clades. Comparison to a Quaternary fossil species from north-west Madagascar, Hipposideros besaoka, found little morphological overlap between any of the three clades and this extinct species. Hence, at least three species of Hipposideros have occurred on Madagascar since the Late Pleistocene, two extant (H. commersoni s.s. and H. cryptovalorona sp. nov.) and one extinct (H. besaoka).
