Description of a new species of the genus Agamura Blanford, 1874 (Squamata: Gekkonidae) from southern Iran.

Herein, we describe a new species of spider gecko, Agamura kermanensis sp. nov., from south Kerman, Iran. The new species is distinguished from other species by having long forelimbs and hindlimbs and a high interorbital distance. Agamura kermanensis sp. nov. was discovered in the Faryab region of southern Kerman Province, which has a xeric climate and low vegetation density. The habitat of the species is similar to that of A. cruralis in southeast Iran. It can be assumed that the distribution of the species is more extensive than currently known. More investigation is required in Jazmourian and the surrounding areas. This is the third species of the genus Agamura discovered on the Iranian Plateau.

A molecular phylogenetic hypothesis for the Asian agamid lizard genus Phrynocephalus reveals discrete biogeographic clades implicated by plate tectonics.

Phylogenetic relationships of the agamid lizard genus Phrynocephalus are described in the context of plate tectonics. A near comprehensive taxon sampling reports three data sets: (1) mitochondrial DNA from ND1 to COI (3' end of ND1, tRNAGln, tRNAIle, tRNAMet, ND2, tRNATrp, tRNAAla, tRNAAsn, tRNACys, tRNATyr, and the 5' end of COI) with 1761 aligned positional sites (1595 included, 839 informative), (2) nuclear RAG-1 DNA with 2760 aligned positional sites (342 informative), and (3) 25 informative allozyme loci with 213 alleles (107 informative when coded as presence/absence). It is hypothesized that Phrynocephalus phyletic patterns and speciation reflect fault lines of ancient plates now in Asia rejuvenated by the more recent Indian and Arabian plate collisions. Molecular estimates of lineage splits are highly congruent with geologic dates from the literature.  A southern origin for the genus in Southwest Asia is resolved in phylogenetic estimates and a northern origin is statistically rejected. On the basis of monophyly and molecular evidence several taxa previously recognized as subspecies are recognized as species: P. hongyuanensis, P. sogdianus, and P. strauchi as "Current Status"; Phrynocephalus bannikovi, Phrynocephalus longicaudatus, Phrynocephalus turcomanus, and Phrynocephalus vindumi are formally "New Status". Phylogenetic evaluation indicates a soft substrate habitat of sand for the shared ancestor of modern Phrynocephalus. Size diversity maximally overlaps in the Caspian Basin and northwestern Iranian Plateau. The greatest species numbers of six in sympatry and regional allopatry are found in the southern Caspian Basin and southern Helmand Basin, both from numerous phylogenetic lineages in close proximity attributed to tectonic induced events.

Phylogenetic relationships of the gray-toad agama, Phrynocephalus scutellatus (Olivier, 1807), species complex from Iran.

The gray toad agama, Phrynocephalus scutellatus (Olivier, 1807) species complex is confined to the Iranian plateau, and forms one of the most widespread, but rarely studied species of the family Agamidae. It represents a complex with many local populations inhabiting a variety of habitats, and exhibiting considerable morphological, genetic and ecological variations. We analyzed sequences of the mitochondrial ND2 gene and tRNA-Trp and tRNA-Ala derived from 89 geographically distant populations. The sequences data strongly support a basal separation of the populations of southeastern-south--central Iran from those occurring in the North. The subsequent radiation, fragmentation, and evolution of these major assemblages have led to four discernible geographical lineages in Iran: southeastern--south-central, west-central, east-northeastern and Khaf. The southeastern--south-central radiation is the earliest lineage and Khaf lineage is probably related to the Afghan plateau. Separation of northern clades from each other can be explained by the presence of large deserts in central Iran. Due to the lack of sufficient geological information, the divergence between the northern and southern clades cannot be explained by the present data.
