|Diagnosis||Diagnosis. A relatively large species of Cordylus, identified to genus by the following combination of characters: four-limbed, rupicolous, viviparous, strongly depressed triangular head and body, osteoderms present, rhomboidal, imbricate and keeled dorsal scales present, occipitals non-spinose, and spinose caudal and limb scales enlarged (Branch 1998; Broadley and Branch 2002; Stanley et al., 2011). Cordylus namakuiyus sp. nov. differs from all other species in the genus except for C. vittifer and C. machadoi, by the presence of a transverse row of elongated dorsal scales immediately posterior to occipitals (vs. absence); from C. vittifer by possessing an incomplete row of pre-occipital scales between posterior parietal and occipital scales (absent in C. vittifer), and by having infralabials that are moderately-deeply corrugated (vs. usually smooth); from C. machadoi by having a large, keyhole-shaped interparietal in broad contact with frontoparietals, thereby separating anterior parietals (vs. small, diamond-shaped interparietal not in contact with frontoparietal, thereby never completely separating anterior parietals), temporal scales that are strongly keeled (vs. weakly keeled), fewer transverse gular rows (14–17 vs. 17– 24), light brown dorsal body coloration (vs. darker brown), and by the absence of dark speckles on throat and ventral body surfaces (vs. presence), presence of osteoderms on throat and ventral surfaces (vs. absence); from C. angolensis (based on original description; Bocage 1895) by having fewer ventral transverse scale rows (21–24 vs. 27), light brown dorsal body coloration (vs. brown with blackish speckles over paler dorsal ground coloration), and by the absence of longitudinal series of whitish speckles along dorsal surface (vs. presence of two longitudinal series of small whitish speckles along dorsum), and presence of a loreal (vs. absence).|
|Etymology||The specific epithet “namakuiyus” is the masculine latinised form of namakuiya, which means “thorny” in the Herero language, referring to the sharp spines on the limbs and tail of this species.|
