Vestiture with the hair and scaling very similar, but with a tendency for the pale hairs on pleural parts, even in the typical Cape form, to be more numerous or more extensive in most specimens and the scales across hind margin of scutellum to be more frequently snow-whitish like the streaks on sides of thorax; pale scaling behind eyes in form of a conspicuous circum-occipital ring of dense white ones, not greyish yellowish on occiput as in abruptus; black hairs and longish dark scales on sides of abdomen distinctly shorter or much shorter, less conspicuously tuft-like or bushy.
