“…Since then, most authors placed mauritaniae within Gerbillus, awaiting the finding of other representatives of this species (Musser and Carleton 2005). To our knowledge, Tranier and Julien-Laferri ere (1990) were the only ones to explicitly notice some morphological similarities between G. nancillus and G. mauritaniae, evoking the possibility that these forms could be synonyms (in which case G. nancillus would be the valid name for this species; see further discussion about this poorly documented taxon in Ndiaye et al 2014).…”

“….comprehensive molecular phylogenetic analysis of the subtribe Gerbillina s. str is needed, as morphological characters are insufficient for the recognition of monophyletic polytypic genera within it'. Accordingly, molecular data were used to test various systematic and phylogenetic hypotheses within the subfamily Gerbillinae (Chevret and Dobigny 2005;Ito et al 2010) Ndiaye et al 2013Ndiaye et al , 2014 for various sibling species).

The systematics of the arid‐adapted Old World Gerbillus rodent genus has always been challenging, with many different taxonomic arrangements proposed. Beyond such taxonomic aspects, the timing and geographical pattern of the evolutionary history of this group remains largely unknown. Based on mitochondrial (cytochrome b) and nuclear (interphotoreceptor retinoid‐binding protein) sequences obtained from the specimens of 21 species, we conducted a phylogenetic analysis of the group, estimated the ages and putative ancestral ranges of its major lineages. Four major clades were clearly retrieved within Gerbillus, for which we propose a subgenus rank. We showed that the emergence of the genus dates back to the end of the Miocene, which corresponds to a period of aridification and C4 vegetation expansion in open habitats, while the four sublineages originated at the end of the Pliocene. Most subsequent diversification events occurred during the Pleistocene, a period characterized by recurrent climatic/environmental shifts with increasing aridification during the last two millions of years. Finally, we suggested that most of the Gerbillus evolutionary history took place in Africa. Only in a few instances did dispersal events from Africa to Asia give birth to extant Asian lineages, a pattern that contrasts with what has been found in many animal groups.

“…The final supermatrix used in the phylogenetic analyses is a concatenation of two mitochondrial ribosomal genes [1019 base pairs (bp) of 12S rRNA; 513 bp of 16S rRNA], eight nuclear protein-coding genes [148 bp of exon 3, 253 bp of intron 2 and 101 bp of exon 4 of acid phosphatase five (ACP5); 754 bp of exon 2, 220 bp of intron 2 and 79 bp of exon 3 of arginine vasopressin receptor 2 (AVPR2); 2388 bp of exon 11 of breast cancer 1 (BRCA1); 1214 bp of intron 3 of benzodiazepine receptor gene (BZRP); 878 bp of exon 10 of growth hormone receptor (GHR); 1122 bp of exon 1 of interphotoreceptor retinoid binding protein (IRBP); 2025 bp of the single exon of recombination activation gene 1 (RAG1); and 1264 bp of exon 28 of von Willebrand factor (VWF)], and three mitochondrial protein-coding genes [324 bp of cytochrome c oxidase I (COI); 684 bp of cytochrome c oxidase II (COII); and 1140 bp of cytochrome b (CYTB)], for a total of 14 126 sites. Most sequences were generated in our laboratory, either new here (27 ACP5, 10 BZRP, 26 CYTB, 5 GHR, 2 IRBP and 5 RAG1) (Appendix 1) or published previously (Steppan et al 2004a(Steppan et al , 2005Rowe et al 2008;Schenk et al 2013), but were supplemented by sequences downloaded from GenBank (mostly published in Michaux et al 2001;Jansa and Weksler 2004;Chevret and Dobigny 2005;Colangelo et al 2007;B€ oselt et al 2009;Ito et al 2010;Ndiaye et al 2014).

Recent molecular studies in gerbils found multiple instances of discordance between molecular and morphological phylogenies. In this study, we analyse the largest molecular data set to date of gerbils and their sister group the deomyines to estimate their phylogenetic relationships. Maximum-likelihood and Bayesian analyses were largely concordant, and both generally had high levels of node support. For gerbils, the results were generally concordant with previous molecular phylogenies based on allozymes, chromosomes, DNA/DNA hybridization and DNA sequences, and discordant with morphological phylogenies. None of the traditional gerbil tribes and subtribes were monophyletic. In addition, paraphyly was found in the genera Gerbillus, Gerbilliscus and Meriones as well as in five subgenera within Dipodillus, Gerbillurus and Meriones. Short branches separating taxa in small clusters within Dipodillus and Meriones suggest synonymy. Within deomyines, all genera and subgenera were monophyletic; however, two species groups within Acomys appear to contain synonymous taxa. We also find support for the discordance between molecular and morphological phylogenies in gerbils being partly due to convergent adaptations to arid environments, primarily in the suite of traits associated with inflation of the tympanic bullae. Relative bullar size does appear to be a desert adaptation and is correlated with aridity independent of phylogeny. Further, it varies more strongly along bioclimatic clines than between binary habitat classifications (desert versus mesic).

Even though Gerbillinae rodents represent an important part of the mammalian fauna in North Africa, many gaps remain in our understanding of the distribution, ecology, evolution, and systematics of some lesser known species in this family. We present in this study the most recent findings on two of these species. The first species, Gerbillus simoni Lataste, 1881, is a short-tailed, small gerbil, endemic to North Africa. In Morocco, it is present only in a small area in the northeast, where it has not been caught since 1970. In 2014, we captured a small gerbil in this region that was identified as G. simoni based on morphology and molecular data (cytochrome b gene sequencing). This study represents the first genetic characterization of G. simoni in Morocco and the first one outside Tunisia. Populations from Morocco and Tunisia (mainland and Kerkennah Islands) show very little genetic differentiation. The second species, Gerbillus henleyi de Winton, 1903, is a long-tailed small gerbil that lives in the Sahel and North Africa with an extension to the Middle East. In Morocco, this species was only known in the southwest. Between 2014 and 2015, we have captured four gerbils in the northeast of the country, which were confirmed genetically and morphologically as belonging to this species. This represents an extension of its known distribution of about 370km to the northeast of the country. These new Moroccan specimens form a distinct lineage. High genetic diversity is observed throughout the geographic range of G. henleyi, suggesting the existence of several cryptic species.
