Herpetology Notes, volume 14: 1-14 (2021) (published online on 08 January 2021) Checklist of amphibians and reptiles of Morocco: A taxonomic update and standard Arabic names Abdellah Bouazza1,*, El Hassan El Mouden2, and Abdeslam Rihane3,4 Abstract. Morocco has one of the highest levels of biodiversity and endemism in the Western Palaearctic, which is mainly attributable to the country’s complex topographic and climatic patterns that favoured allopatric speciation. Taxonomic studies of Moroccan amphibians and reptiles have increased noticeably during the last few decades, including the recognition of new species and the revision of other taxa. In this study, we provide a taxonomically updated checklist and notes on nomenclatural changes based on studies published before April 2020. The updated checklist includes 130 extant species (i.e., 14 amphibians and 116 reptiles, including six sea turtles), increasing considerably the number of species compared to previous recent assessments. Arabic names of the species are also provided as a response to the demands of many Moroccan naturalists. Keywords.

Pleguezuelos et al., 2010; del Mármol et al., 2019). The earliest studies on Moroccan herpetofauna were This is mainly because Morocco comprises several conducted during the first half of the 19th century (Busack, mountain chains (i.e., Rif and Atlas chains) that form 1976). At that time, the list of Moroccan amphibians distinct geographic barriers and divide the country into and reptiles included only about ten taxa (Gervais, many topographically and climatically complex regions 1836). Since the 1870’s, North Africa has witnessed a (Sobrino and Raissouni, 2000). Moreover, its contact growing interest in herpetology (e.g., Boettger, 1874, with Europe during the Messinian Salinity Crisis (~5.6 1883, 1885; Camerano, 1882; Boulenger, 1889, 1891). During the 20th century, various herpetological research projects have been developed in Morocco among which those with the aim of compiling species lists, providing illustrated keys and identification guides, and mapping 1 Biotechnology, Materials and Environment Laboratory, species distribution (e.g., Boulenger, 1919; Pellegrin, Polydisciplinary Faculty of Taroudant, Ibn Zohr University, 1925; Guibé, 1950; Aellen, 1951; Saint-Girons, 1956; Agadir, Morocco.

Our taxonomic list was limited to the specific level During the last decade, Pleguezuelos et al.

Recently, del Mármol et al. encyclopaedia of Ghālib (1988); these names could be (2019) published a new book on Moroccan amphibians reviewed following constructive criticism from Arabic and reptiles, cataloguing 14 amphibians and 103 reptiles scholars. In some cases, Moroccan names (Arabic excluding sea turtles. Since then, a significant number dialect) used by local people are added to the list (e.g., of newly recognised species have been described (e.g., Snakes; Fahd and Pleguezuelos, 2001).

For sea Turtles, which More than one-fourth (i.e., 26%) of the listed were not treated previously by several authors (e.g., herpetofaunal species are considered to be endemic to Pleguezuelos et al., 2010; del Mármol et al., 2019), Morocco, with amphibians and reptiles including two we based our analysis on the book of Bons and Geniez and 31 endemics respectively. The rate of endemism (1996). is highest in the family of Scincidae (nine endemic Our work focused on species and genus level species), followed by Sphaerodactylidae (eight species), changes, as well as some cases of particular interest Lacertidae (seven species), and Blanidae (two species); to the herpetological community. For species-level the remaining endemic species represent one family systematics, we followed the conception of Speybroeck each. et al. (2010) and Hillis (2019). In the main, we adhere to the “Biological Species Concept” and we prefer, Discussion for recognising a species, to put more emphasis on the Amphibians degree of extrinsic or intrinsic reproductive isolation, Endemic species rather than treating all evolutionary units as species. To do so, we considered molecular, morphological, Pelobates varaldii Pasteur and Bons, 1959 is an and ecological information, when available, as possible endemic species to Morocco, whereas Barbarophryne indicators to interpret the degree of isolation.
