|Distribution||Republic of South Africa (Suurberg/Hounslow near Grahamstown)|
Type locality: Hounslow, near Grahamstown, Cape Province.
|Types||Lectotype: PEM R11157 (designated by BRANCH et al. 1995); Syntype: UMMZ 61515|
|Diagnosis||Diagnosis: Distinguished from other members of the P. lineatus complex by a combination of the following features: Usually four preanal pores in males, a medium number of midbody scale rows (78-84), 9-12 scales between the nostril and anterior margin of the orbit, (only 0-2 nasorostrals, and a dorso-ventrally flattened head and body. In addition, it differs by 5-8 fixed alleles from the other taxa examined electrophoretically (Branch et al. 1995).|
Description: Head dorso-ventrally flattened (depth 1.95 times width; range 1.53-2.46); snout rounded, and at least 1.5 times the eye diameter; ear opening small, obliquely rounded, and without enlarged lobules or a tympanic shield; rostral subpentagonal with a median cleft above; nostril pierced between rostral, 1st supralabial and three nasals, the largest bordering the rostral; usually I (33.3%) or 2 (41.7%) nasorostral grannles, rarely 0 (12.5%) or 3 (12.5%); supralabials usually 7 (66.6%), often 8 (27.8%), rarely 9 (5.6%); infralabials usually 7 (77.8%), sometimes 6 (22.2%); mental subpentagular bordered by 2-3 (average 2.14) chinshields that are larger than adjacent granules; 5-9 (average 6.45) granules bordering chinshields. Body short (maximum snout-vent length 28.4 mm) and dorsoventrally flattened, covered dorsally with uniform, smooth, flattened, subimbricate granules; belly covered in smooth, hexagonal, imbricate scales that are much larger than on back. Limbs moderate and covered in uniform, flattened, subimbricate granules; digits flattened basally, with three rows of subdigital granules, the median series slightly broader; toe tips rounded, only slightly expanded and bearing a pair of large, subrectangular scansors that enclose a small claw. An angular series of 4 (100%, n = 7) preanal pores present only in males; two to three enlarged tubercular scales on either side of tail base near vent, that are larger in males. Original tail cylindrical, tapering, and subequal to (max. 0.912 times) snout-vent length; covered above with regular rows of uniform, smooth granules, that are much larger, flattened and imbricate on ventral surface (Branch et al. 1995: 39, Figure 1A).
Colour: (PEM R7236, Farm Hounslow, Grahamstown District). Above grey-brown with irregular series of 5-6 pale spots, emargined anteriorly in dark brown (in some specimens the dark edges fuse to form an irregular series of 8-10 scalloped bars); back of head, temporal region and upper surfaces of limbs pale brown with dark reticulation; a vague dark band extends from middle of eye on to the snout; original tail with irregular bars formed from the fused, dark anterior margins of paired vertebral pale spots; lower surfaces of throat, belly, limbs and tail, dirty cream. The pattern in some specimens (eg. PEM R 11711, Pluto's Vale, Albany District) is obscured by heavy stippling, that extends on to the ventrum (Branch et al. 1995).
|Etymology||Named after Robert Essex who worked as a collector at the Albany Museum when Hewitt was Director there. Essex also described two new Acontias.|
