(2006) - Lizards of Ethiopia (Reptilia Sauria):an annotated checklist, bibliography,gazetteer and identification key. - Tropical Zoology, 19 (1): 21-109.   × This review lists Agama smithii Boulenger 1896 as a synonym of Agama agama
(Linnaeus 1758), Agama trachypleura Peters 1982 as a synonym of Acanthocercus
phillipsii (Boulenger 1895) and describes for the first time Acanthocercus guentherpetersi
n. sp. Without more convincing evidence, Chamaeleon ruspolii Boettger 1893
cannot be accepted as specifically distinct from Chamaeleo dilepis Leach 1819, nor
Chamaeleo calcaricarens Böhme 1985 from C. africanus Laurenti 1768.
Consequently, 101 species of lizard are currently recognised in Ethiopia,
of which some 40% appear to be denizens of the Somali-arid zone. This significant
proportion is attributable in part to the importance of the Horn of Africa
as a centre for reptilian diversification and endemicity, in part to the fact that
this lowland fauna was rather extensively sampled during the 1930s, but also to
the conspicuous neglect of lizards in other regions of the country. Mountain and
forested habitats are widespread in Ethiopia, so it seems extraordinary to record
only five saurian species which are believed to be endemic in such environments.
The inference that there are many more still to be discovered has important
implications for conservation, because montane forest is known to be among the
most threatened of Ethiopian biomes and there is clearly an urgent need for its
herpetofauna to be more thoroughly researched and documented. Engleder, A. & Haring, E. & Kirchhof, S. & Mayer, W. (2013) - Multiple nuclear and mitochondrial DNA sequences provide new insights into the phylogeny of South African Lacertids (Lacertidae, Eremiadinae). - Journal of Zoological Systematics and Evolutionary Research, Berlin, 51 (2): 132-143. × Eremiadinae, one of three subfamilies of Lacertidae, are distributed throughout Asia and Africa. Previous phylogenetic studies suggested that one of
the main groups of Eremiadinae (the Ethiopian clade) consist of two clades with predominately East-African and South-African distribution. Yet, especially
the latter one, which includes the genera Pedioplanis, Meroles, Ichnotropis, Tropidosaura and Australolacerta, was not well supported in the
molecular phylogenetic analysis. In this study, we analysed the phylogenetic relationships among the genera of the ‘South African clade’ to assess
whether this group actually forms a highly supported clade and to address questions concerning the monophyly of the genera. We sequenced sections
of the widely used mitochondrial genes coding for 16S rRNA, 12S rRNA and cytochrome b (altogether 2045 bp) as well as the nuclear genes c-mos,
RAG-1, PRLR, KIF24, EXPH5 and RAG-2 (altogether 4473 bp). The combined data set increased the support values for several nodes considerably.
Yet, the relationships among five major lineages within the ‘South African clade’ are not clearly resolved even with this large data set. We interpret
this as a ‘hard polytomy’ due to fast radiation within the South African lacertids. The combined tree based on nine marker genes provides strong support
for the ‘South African Clade’ and its sister group relationship with the ‘East African Clade’. Our results confirm the genus Tropidosaura as a
monophylum, while Ichnotropis is paraphyletic in our trees: Ichnotropis squamulosa appears more closely related to Meroles than to Ichnotropis capensis.
Furthermore, the monophyly of Meroles is questionable as well. Based on our results, I. squamulosa should be transferred from Ichnotropis into
the genus Meroles. Also, the two species of Australolacerta (A. australis and A. rupicola) are very distantly related and the genus is perhaps paraphyletic,
too. Finally we propose a phylogeographical scenario in the context of palaeoclimatic data and compare it with a previously postulated hypothesis.
