A molecular phylogeny of the sphaerodactylid geckos genus Pristurus is inferred based on an alignment 1845 base pairs (bp) concatenated mitochondrial (12S) and nuclear (acm4, cmos, rag1 rag2) genes for 80 individuals, representing 18 23–26 species, three subspecies P. rupestris. The results indicate that rupestris polyphyletic includes two highly divergent clades: eastern clade, found in coastal Iran throughout Hajar Mountain range northern Oman UAE; western distributed from central Oman,...
In the present work, we use an exceptional database including 5,359 records of 101 species Oman's terrestrial reptiles together with spatial tools to infer patterns richness and endemicity, habitat preference each better define conservation priorities, especial focus on effectiveness protected areas in preserving this unique arid fauna. Our results indicate that sampling effort is not only remarkable from a taxonomic point view, multiple observations for most species, but also coverage...
How evolutionary novelties evolve is a major question in biology. It widely accepted that changes environmental conditions shift the position of selective optima, and advancements phylogenetic comparative approaches allow rigorous testing such correlated transitions. A longstanding vertebrate biology has been evolution terrestrial life histories amphibians here, by investigating African bufonids, we test whether modes reproduction have evolved as adaptations to particular abiotic habitat...
In the last decade, taxonomic studies have drastically increased number of species known to inhabit Arabian deserts. While ongoing phylogenetic continue identify new and high levels intraspecific genetic diversity, few yet explored biogeographic patterns in this arid region using an integrative approach. present work, we apply different methods infer relationships within Palearctic naked-toed geckos. We specifically address for first time taxonomy biogeography Bunopus spatalurus Anderson,...
The gecko genus Hemidactylus, with its 132 currently recognized species, ranks among the most species-rich reptile genera. Recent phylogenetic studies disclosed unexpectedly high genetic variability and complex biogeographic history within arid clade distributed in Mediterranean, Northeast Africa, Middle East Indian subcontinent. Particularly, species from Arabian Peninsula have been lately subject of many taxonomic revisions that resulted descriptions 16 new taxa. Yet not all detected...
Atractaspidines are poorly studied, fossorial snakes that found throughout Africa and western Asia, including the Middle East. We employed concatenated gene-tree analyses divergence dating approaches to investigate evolutionary relationships biogeographic patterns of atractaspidines with a multi-locus data set consisting three mitochondrial (16S, cyt b, ND4) two nuclear genes (c-mos RAG1). sampled 91 individuals from both atractaspidine genera (Atractaspis Homoroselaps). Additionally, we...
Hemiscorpius novaki sp. n. from Somaliland is described and compared with other African species of the genus. The new characterized chiefly by total length 40–46 mm; yellow to yellowish-brown color pedipalp fingers reddish brown black, darker than chela; slightly longer metasoma in male female. These characters distinguish H. somalicus Lourenço, 2011. third genus, tellinii Borelli, 1904, known only female holotype, which differs females having much less pronounced granulation dorsal carinae...
The Horn of Africa supports a unique and rich diversity squamate reptiles. Among them, the gecko genus Hemidactylus stands out as most species-rich region. In this study, we assembled genetic morphological data set 22 species that form clade termed African radiation, which is part arid genus. We reconstructed their phylogenetic relationships using both concatenation-based approaches tree inference. laevis, H. ophiolepoides, somalicus have been sequenced placed in context for first time...
Approximately 120 years after its description, this is the first thorough systematic review of agamid genus Xenagama. Currently, includes two extraordinary species, characterized by strongly discoidal tails. Both species are only known from a few localities in north-eastern Ethiopia and northern Somalia represented small number specimens museum collections. Morphological mitochondrial (16S) DNA sequence data revealed that Xenagama batillifera complex cryptic reassignment Acanthocercus...
Geckos are one of the most species-rich, abundant, and widely distributed all Squamata lineages present several characteristics that have made them favorite model organisms for biogeographical, ecological, physiological, evolutionary studies. One key aspects any comparative study is to a robust, comprehensive phylogeny, an updated taxonomy. Recently, Infraorder Gekkota has been subject phylogenetic analyses taxonomic revisions at different levels. Despite these advances, there still some...
Three new species H. gambelaensis Kovařík, sp. n., gibaensis n. and novaki from Ethiopia are described, compared with other fully illustrated color photos of habitus localities. Data about the distribution Hottentotta in including all seven known their Ethiopian localities summarized.
AbstractThe taxonomy of many Hemidactylus geckos from the Horn Africa has recently been evaluated. However, lack fresh material for some species and also regions led to misidentification taxa an underestimation true diversity in others. In this study we analyse new collected poorly known coastal areas northern Somaliland. Our results support existence two yet undescribed within arid clade. One is small-sized closely related H. afarensis Afar Triangle Ethiopia, together with other (H....
The family Ptychadenidae contains three ecologically and morphologically distinct genera: the widespread, species-rich above-ground dwelling Ptychadena, less widespread diverse, burrowing Hildebrandtia, little-known, burrowing, monotypic Lanzarana, endemic to Somalia. Previous morphological studies placed Lanzarana in a sister position Hildebrandtia these two genera as Ptychadena. However, our analyses of mitochondrial multilocus nuclear DNA data revealed lineage Ptychadena (divergence ∼28...
The Horn of Africa is a center diversity for African agamid lizards. Among the nine species Agama occurring in Africa, spinosa most widely distributed. A. group (sensu stricto, morphologically defined by possessing six clusters spinose scales around ear) contains two species: occurs from Egypt to Ethiopia and Somalia where it replaced distinct therefore sensu lato bottegi . Both are only represented museum collections small number specimens Somalia, presumably result constant civil war that...
We describe herein two new species, Gint dabakalo sp. n. from Somaliland and G. puntlandus Somalia (Puntland) (Scorpiones: Buthidae). Additional information is given on taxonomy distribution of all four species genus Kovařík et al., 2013, fully complemented with color photos live preserved specimens, as well their habitats. True male calviceps documented for first time, validates original decisions to create separate Gint, transfer Buthacus Pocock, 1900, that genus.
Telescopus pulcher is an enigmatic colubrid snake only known from the holotype and paratype specimens described ‘Migiurtinia’ in Puntland (Somalia) 1935. Herein we recorded third fourth-ever of this species Toon village, Woqooyi Galbeed Region, 15 km southeast Sheikh, Saahil Somaliland. The endemic to Somaliland adjoining parts Ethiopia Puntland. Data on morphology natural history, as well first photographs live are provided. We also provide a detailed description paratype. coloration...
The biological diversity of the Horn Africa is one least studied in world. Yet supports rich communities species that are mostly endemic to region. Here we study Sand Snakes ( Psammophis ) East Africa, their phylogeny and systematics. Previous studies have unveiled several cryptic potentially undescribed occur taxonomic status has remained unclear this day. We used sequence data from two mitochondrial nuclear genes reconstruct genus, which included newly obtained samples six different...
Because of a recent taxonomic revision, the species identity helmeted terrapins (Pelomedusa) became unclear in many regions their wide distribution range. Based on mtDNA sequence data, here we present first record Pelomedusa subrufa sensu stricto for South African province Mpumalanga.
