“…Integrative taxonomic diagnoses of the various clades supported by our analyses will be necessary to determine which, if any, existing names may apply to them. However, to relate our results to those of earlier studies of African Hipposideros (Vallo et al 2008Monadjem et al 2013), we cross-referenced specimens used in two or more analyses to equate the various non-binomial names that have been applied to these cryptic lineages.…”

“…Only one extant species has been described since the recognition of Hipposideros lamottei (Brosset 1985(Brosset ["1984), and that one was from Madagascar . Surveys of mitochondrial sequences from African hipposiderids have strongly suggested that supposedly widespread species such as Hipposideros caffer and H. ruber actually represent complexes of cryptic species (Vallo et al 2008Monadjem et al 2013). Phylogenetic analyses (e.g., Vallo et al 2008) show that these named species complexes are not monophyletic, resolving clades comprised of bats identified as both H. caffer and H. ruber.…”

The Old World leaf-nosed bats (Hipposideridae) are aerial and gleaning insectivores that occur throughout the Paleotropics. Both their taxonomic and phylogenetic histories are confused. Until recently, the family included genera now allocated to the Rhinonycteridae and was recognized as a subfamily of Rhinolophidae. Evidence that Hipposideridae diverged from both Rhinolophidae and Rhinonycteridae in the Eocene confirmed their family rank, but their intrafamilial relationships remain poorly resolved. We examined genetic variation in the Afrotropical hipposiderids Doryrhina, Hipposideros, and Macronycteris using relatively dense taxon-sampling throughout East Africa and neighboring regions. Variation in both mitochondrial (cyt-b) and four nuclear intron sequences (ACOX2, COPS, ROGDI, STAT5) were analyzed using both maximum likelihood and Bayesian inference methods. We used intron sequences and the lineage delimitation method BPP-a multilocus, multi-species coalescent approach-on supported mitochondrial clades to identify those acting as independent evolutionary lineages. The program StarBEAST was used on the intron sequences to produce a species tree of the sampled Afrotropical hipposiderids. All genetic analyses strongly support generic monophyly, with Doryrhina and Macronycteris as Afrotropical sister genera distinct from a Paleotropical Hipposideros; mitochondrial analyses interpose the genera Aselliscus, Coelops, and Asellia between these clades. Mitochondrial analyses also suggest at least two separate A peer-reviewed open-access journal B. D. Patterson et al. / ZooKeys 929: 117-161 (2020) 118 colonizations of Africa by Asian groups of Hipposideros, but the actual number and direction of faunal interchanges will hinge on placement of the unsampled African-Arabian species H. megalotis. Mitochondrial sequences further identify a large number of geographically structured clades within species of all three genera. However, in sharp contrast to this pattern, the four nuclear introns fail to distinguish many of these groups and their geographic structuring disappears. Various distinctive mitochondrial clades are consolidated in the intron-based gene trees and delimitation analyses, calling into question their evolutionary independence or else indicating their very recent divergence. At the same time, there is now compelling genetic evidence in both mitochondrial and nuclear sequences for several additional unnamed species among the Afrotropical Hipposideros. Conflicting appraisals of differentiation among the Afrotropical hipposiderids based on mitochondrial and nuclear loci must be adjudicated by large-scale integrative analyses of echolocation calls, quantitative morphology, and geometric morphometrics. Integrative analyses will also help to resolve the challenging taxonomic issues posed by the diversification of the many lineages associated with H. caffer and H. ruber.

“…Indeed, acoustic divergence in cryptic bat species may be more likely to occur in high duty cycle echolocating taxa such as the Hipposideridae, and, amongst this bat family, acoustic signatures are reliable indicators of species identity (Jones & Barlow, 2004). However, the recognition of morphologically similar taxa can be easily confounded with animals in the hand, specifically cryptic species, as at certain sites in tropical regions species richness of members of this genus can be considerable, such as on Mt Nimba in West Africa, which has seven sympatric taxa (Monadjem et al, 2013) or the Tai and Comoé National Parks of Côte d'Ivoire with five and six species, respectively (Fahr & Kalko, 2011).…”

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).

“…They include rich small mammal assemblages for which new species continue to be discovered (e.g. Petter, ; Dieterlen & van der Straeten, , ; Van der Straeten & Hutterer, ; Hutterer, Dieterlen & Nikolaus, ; Dieterlen & Van der Straeten, ; Verheyen et al ., ; Fahr et al ., ; Lecompte, Granjon & Denys, ; Missoup et al ., ; Monadjem et al ., , b; Denys et al ., ). The closest relatives of many of these West African endemics are confined to the mountains of the eastern African Great Rift Valley and the Eastern Arc Mountains, suggesting either ancient forest (Miocene) connections (as suggested for the shrew genus Congosorex ; Stanley, Rogers & Hutterer, ), or possibly more recent dispersal events along historical temperate corridors (e.g.…”

West African Mountains of the Cameroon Volcanic Line harbour two montane‐endemic species of laminated‐toothed rats (Otomys), which represent the most westerly occurrence of the genus. We explore here through mtDNA sequencing and cranial morphometrics the taxonomic status and phylogenetic relationships of O. burtoni (Mt Cameroon) and O. occidentalis (Mts Oku and Gotel). We conclude that both species are valid and can be discriminated by molecular data, as well as quantitative and qualitative cranial characters. From molecular data, O. occidentalis and O. burtoni are closest neighbours (p‐distance = 7.5–8.5%) and weakly associated sister species (suggesting a single West African radiation) and both are sister clades to a well supported clade of central, East and northeast African members of the O. typus s.l. and O. tropicalis s.l. species complexes from mountain ranges comprising the East African ‘Montane Circle’ and Ethiopian Highlands. Re‐evaluation of the evolutionary origins of the allopatric Otomys populations in equatorial Africa is undertaken in light of fossil evidence of a southern African origin of the genus. We can conclude that Otomys reached the Cameroon Volcanic Line via corridors of temperate grasslands during the Late Pliocene. Our data support the hypothesis that, following major peripatric speciation events at around 2.3 to 2.03 Ma (from East Africa into West and North Africa respectively), further speciation occurred across neighbouring mountain ranges in West, Central‐East and North‐East Africa. Estimated molecular dates of speciation events in Otomys reveal close congruence with well‐constrained geochronological estimates, pertinently the uplift of the Albertine Rift in the Early Pleistocene. These regional analyses reveal how peripatric speciation events established narrow‐range endemics of Otomys on principal stratovolcanoes across the East African plateau and Cameroon. © 2014 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 113, 320–344.
