(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.

(2022) - The Angolan bushveld lizards, genus Heliobolus Fitzinger, 1843 (Squamata: Lacertidae): Integrative taxonomy and the description of two new species. - Vertebrate Zoology, 72: 745–769 (DOI 10.3897/vz.72.e85269). × The genus Heliobolus comprises four recognized species, all endemic to sub-Saharan Africa. Of these, only Heliobolus lugubris occurs in southern Africa, its distribution extending from Angola in the west to Mozambique in the east and reaching as far south as parts of northern South Africa. Like many of the reptile species that occur in southern Africa, Heliobolus lugubris is poorly studied, and preliminary investigation suggested that it may contain cryptic diversity. The present work focusses on the Angolan population of H. lugubris and uses an integrative taxonomic approach based on morphological, coloration and DNA sequence data. The results indicate that some of the current and historical specimens of H. lugubris from Angola do not correspond to the nominotypical form, and that differences between specimens suggest the presence of two additional species, described here as Heliobolus bivari sp. nov. from the southernmost xeric/desertic regions and plateau of Namibe Province, southwestern Angola and H. crawfordi sp. nov. from the Serra da Neve inselberg north through the sub-desert coastal regions of northern Namibe, Benguela, and Kwanza Sul provinces. Nominotypical Heliobolus lugubris is confirmed to occur in Cuando Cubango Province, southeastern Angola.
