|Diagnosis||Diagnosis.*SVL to at least 40.9 mm. A small, rupicolous Pachydactylus with a depressed body form. Dorsum atuberculate, with smooth, flat, round granules, grading to subimbricate scales on flanks. OrbD smaller than EyeEar. Rostral excluded from nostril rim. Enlarged conical scales restricted to dorsal side of crus. Tail indistinctly segmented with juxtaposed to subimbricate scalation. Dorsal pattern uniform dark brown with numerous white flecks throughout.|
Pachydactylus maraisi is most similar to other members of the ‘northwestern clade’ of Pachydactylus. Within this clade, Pachydactylus maraisi can be readily distinguished from P. angolensis, P. boehmei, P. gaiasensis, P. oreophilus, P. otaviensis, P. parascutatus, P. sansteynae, and P. scutatus by its lack of enlarged, keeled dorsal scales or tubercles (present in others). From P. bicolor, P. caraculicus, and P. scherzi, P. maraisi differs in colour pattern, lacking transverse bands or blotches (Fig. 1C, 2) (present in other species). In addition, P. caraculicus differs from P. maraisi in having subimbricate dorsal scales, some of which are keeled, having imbricate scales on the tail (juxtaposed to subimbricate in P. maraisi), having fewer adhesive lamellae (three or four per digit, vs. five to seven in P. maraisi), and, in males, having only two scales per cloacal spur (four to five in P. maraisi). Pachydactylus punctatus and P. scherzi differ from P. maraisi in body shape, being noticeably rounder in cross section with weakly convex snouts, having fewer adhesive lamellae (three or four per digit), having the first supralabial sometimes participating in nostril rim, having an unsegmented tail, and having three granules separating the dorsal postnasals. The most similar species to P. maraisi is P. bicolor, but P. bicolor (in addition to colouration differences) has a more robust, thickset appearance, with noticeably shorter limbs and digits (CrusL/SVL ratio mean 0.18 in 13 measured P. maraisi, 0.16 in 16 measured P. bicolor; t-test p=0.002), has fewer adhesive lamellae (up to 5 per digit; always 6 on at least some digits in P. maraisi), and has imbricate scalation on the tail [from HEINICKE et al. 2011].
|Etymology||Etymology.”Named for our friend and colleague Johan Marais, collector of some individuals of the type series, and in recognition of his contributions to both academic and popular herpetology in southern Africa. The epithet is formed in the masculine genitive.” [from HEINICKE et al. 2011].|
