Acontias jappi (Broadley, 1968) View in CoL
Barotse Legless Skink
Material: TM 86232–34, TM 86254
Individuals were collected in soil under bush clumps near Ngonye Falls campsite, airstrip and Park Headquarters ( Fig. 2e View Fig ). Numerous additional individuals were unearthed during the construction of Park Headquarters. Originally described as a subspecies of Acontias kgalagadi (previously Typhlosaurus lineatus [Boulenger, 1887]), Schneider and Bauer (2009) elevated this taxon to species status on morphological grounds. Specimens were distinguished from A. k. kgalagadi on the basis of being significantly more robust, having only two longitudinal dark stripes which fade out on the tail (typically 4–8 in A. k. kgalagadi ); 24–25 subcaudal scales (26–35 in A. k. kgalagadi ), the ocular scale being longer than high (as long as high in A. k. kgalagadi ), and only three sublingual scales border the mental (usually four in A. k. kgalagadi ; Broadley 1968b; Branch 1998). TM 86232– 34 have four supralabials and three infralabials on each side, while TM 86233 has the mental longitudinally divided into two subequal parts (undivided in the remaining specimens). The superior border of the ocular scale is incompletely fused with the anterior supraciliary on both sides in all four specimens, resulting in a narrow slit that is apparently continuous with the eye (i.e., an immovable lower eyelid). Most other members of Acontias have the eye either completely covered by an ocular scale or have a moveable lower eyelid ( Branch 1998), with only A. rie- pelli having an immovable lower eyelid ( Branch 1998). Acontias jappi is restricted to south-western Zambia and adjacent Angola ( Broadley 1968b, 1971a; Schneider and Bauer 2009).
