Pseudotrapelus
MELNIKOV, D.A. & E.N. MELNIKOVA (2013): Taxonomic diversity of the genus Pseudotrapelus (Agamidae; Sauria) and biogeography of Afro-Arabia. [in Russian, with English Abstract]. - Proceedings of the Zoological Institute of the Russian Academy of Sciences 317 (4): 438–451.

This is the first annotated check-list on taxonomic structure of Pseudotrapelus, a genus that was considered previously to be monotypic. The paper is based on a large collection (more than 250 specimens from the whole range of the genus), and represents the first publication about this genus in Russian. Five Pseudotrapelus species are divided into two groups: the African one with Ps. sinaitus sensu stricto and the Arabian one with Ps. neumanni, Ps. aqabensis, Ps. dhofarensis and Ps. jensvindumi. The division into two groups was caused, probably, by separation of Arabia from Africa 28–23 mya. The collision of these landmasses via the Gomphoterium land bridge, south from the Sinai Peninsula 18–15 mya caused the secondary colonization of Arabia by Pseudotrapelus (this time by Ps. sinaitus) and formation of the sympathry zone and, probably, hybridization with the Arabian species group in the Aqaba area. South-Western Arabia is the center of recent taxonomic diversity of Pseudotrapelus.

from tectonic movements and continuous geological activity to shifting climatic conditions. The effect of these events on the distribution and diversity of the regional biota is still poorly understood. Agamid members of the genus Pseudotrapelus are diurnal, arid-adapted lizards distributed around the Red Sea from north-eastern Africa, across the mountains and rocky plateaus of the Sinai and Arabian Peninsulas northwards to Syria. Despite recent taxonomic work and the interest in the group as a model for studying biogeographic and diversity patterns of the arid areas of North Africa and Arabia, its taxonomy is poorly understood and a comprehensive phylogeny is still lacking. In this study, we analyzed 92 Pseudotrapelus specimens from across the entire distribution range of the genus. We included all known species and subspecies, and sequenced them for mitochondrial (16S, ND4 and tRNAs) and nuclear (MC1R, c-mos) markers. This enabled us to obtain the first time-calibrated molecular phylogeny of the genus, using gene trees, species trees and coalescent-based methods for species delimitation. Our results revealed Pseudotrapelus as a monophyletic genus comprised of two major clades and six independently evolving lineages. These lineages correspond to the five currently recognized species and a sixth lineage relating to the synonymized P. neumanni. The subspecific validity of P. sinaitus werneri needs further assessment as it does not form a distinct cluster relative to P. s. sinaitus. The onset of Pseudotrapelus diversification is estimated to have occurred in Arabia during the late Miocene. Radiation has likely resulted from vicariance and dispersal events due to the continued geological instability, sea level fluctuations and climatic changes within the region.


Pseudotralepus aqabensis MELNIKOV, NAZAROV, ANAJEA & DISI, 2012


MELNIKOV, D.A., MELNIKOVA, E.N., MILTO, K.D. & N.B. ANANJEVA (2014): On an occurrence of Pseudotrapelus aqabensis Melnikov, Nazarov, Ananjeva et Disi, 2012 in the Sinai Peninsula, Egypt. - Current Studies in Herpetology, 14 (1/2): 27-31.

Data on a new occurrence of Ps. aqabensis in the Sinai peninsula, Egypt, are presented. The specimens from the Taba prefecture are characterized by the morphological and genetic characters of Ps. aqabensis. All the specimens studied have their third toe longer than the fourth one, and males have four welldeveloped preanal pores separated from each other. The sequences of mtDNA (COI and ND2) and nuclear DNA (RAG1) fragments are similar to those of the specimens from the typical locality of Ps. aqabensis, including the Holotype. We assume that Ps. aqabensis has penetrates to the Sinai Peninsula from the Arabia. This direction is opposite to the Ps. sinaitus penetration from Africa to Arabia, which was proposed in our earlier paper based on the study of more than 150 sequences of mitochondrial (COI and ND2) and nuclear (RAG1) DNA of all Pseudotrapelus species from whole distributional range. It was shown very low genetic variability of Ps. sinaitus from the most south-western locality in African Egypt (Azraq) through the type locality of the species (mountain Sinai) to the north-eastern Jordan (Mquat). This indicates a very fast species expansion through the paleo-bridge that connecting Africa and Asia in the past. While recent features as geographic barriers – Red Sea, Suez and Aqaba bay, are not affecting the molecular-genetic structure of the species. The history of Ps. aqabensis и Ps. sinaitus colonization of this territory is complicated and needs further investigations.

A new species of Pseudotrapelus from Aqaba, southern Jordan is described. It differs from P. sinaitus in four well developed separated preanal pores in males, 3rd toe much longer than 4th and 16% incorrect p-distance (COI). Taxonomic relationships between Arabian Peninsula Pseudotrapelus need further investigations.

A new species of Pseudotrapelus from Dhofar, Oman is described. It differs morphologically from P. sinaitus in that its 3rd toe is much longer than its 4th one (11–13 lamellae under the 4th toe), from P. aqabensis and P. neumanni in that it has one row of 6 – 8 unseparated precloacal pores in males. This new species also has 15% genetic divergence from P. sinaitus and 10% from P. aqabensis (COI). Taxonomic relationships of Arabian Peninsula Pseudotrapelus need further investigations.

A new species of Pseudotrapelus from Nizwa, Oman is described. It differs morphologically from P. sinaitus in that its 3rd toe is much longer than its 4th (14 lamellae under the 4th toe), from P. aqabensis, P. dhofarensis, and P. neumanni in that it has one row of 4 unseparated precloacal pores in males. This new species also has 16.6% genetic divergence from P. sinaitus, 11% from P. aqabensis and 11.2% from P. dhofarensis (COI). Taxonomic relationships of Arabian Peninsula Pseudotrapelus need further investigations.

Kurzfassung:
Die Untersuchungen von 67 Exemplaren der Sinai-Agame Pseudotrapelus sinaitus (HEYDEN, 1827) aus Syrien, Jordanien, Israel und der Sinai-Halbinsel zeigte, dass in diesem Gebiet zwei Unterarten vorkommen: (1) die nominotypische Subspeczies Pseudotrapelus sinaitus sinaitus (HEYDEN,1827) die vom Sinai bis zum mittleren Israel und zum mittleren Jardanien verbreitet ist, und (2) eine bislang unbeschriebene Unterart, die in der Basaltwüste des südlichen Syriens und des nördlichen Jordaniens endemisch ist. Letztere Unterart wird hier als Pseudotrapelus sinaitus werneri n. ssp. Beschrieben. Beide Subspezies unterscheiden sich am deutlichsten in der Körpergröße, der Lamellenzahl unter der vierten Zehe, der Schuppenzahl um die Körpermitte, der zahl der präkloakalen Callusdrüsen und im Längenverhältnis des dritten und vierten Zehs.
