Diagnosis | Diagnosis (genus). The inclusion of M. squamulosus requires the genus to be redefined. Head shields normal and usually smooth (rugose in squamulosus), but occipital often very small or absent; nostril pierced between three nasals and widely separated from 1stupper labial; subocular not bordering mouth; lower eyelid scaly, without window; collar distinct (absent in squamulosus); gular fold absent; dorsal scales granular, juxtaposed or subimbricate, (but rhombic, strongly keeled and imbricate in squamulosus); ventral plates smooth, not or feebly imbricate, posterior borders straight; digits subcylindrical, compressed or depressed (feebly compressed in squamulosus), laterally serrated, denticulated or fringed (except in squamulosus); subdigital lamellae smooth or keeled (pluricarinate and spinolose in squamulosus), femoral pores present; parietal foramen present (absent or feebly marked in squamulosus); and tail long and cylindrical (in knoxii, suborbitalis and squamulosus) or depressed basally and feebly compressed distally [from EDWARDS et al. 2013]. |
Comment | Subspecies: FITZSIMONS 1943 listed Scaptira knoxii pequensis HEWITT 1935 as subspecies (Type locality: Lüderitzbucht). SZCZERBAK 1989 listed Meroles knoxii pequensis (Type locality: Bay of Lüderitz, Southwest Africa). However, BISCHOFF 1991 does not list any subspecies which is why we inlcuded it in the synonymy. Type species: Meroles knoxii (Milne-Edwards 1829) is the type species of the genus Meroles GRAY 1838. |
Etymology | Named after Dr. Robert Knox (1791-1862), a physician, anatomist, natural scientist, and traveler. |
