| Diagnosis | |
| Comment | Eastern race of Z. vandami. Has been treated as synonym of Zygaspis violacea (e.g. LOVERIDGE 1941). Sympatric with Z. quadrifrons in the N Krüger National Park. Habitat: Z. v. vandami FitzSimons usually under stones or logs on sandy or humus-rich soils along the eastern escarpment of South Africa, while Z. v. arenicola is found in alluvial sands on the Mozambique Plain, extending into north-eastern KwaZulu-Natal, South Africa, north-eastern Swaziland, and inland to the Cretaceous sands of south-eastern Zimbabwe (Jacobsen 1989, as Z. violacea; Broadley & Broadley 1997; Litschka, Koen & Monadjem 2008). Typically, Zygaspis v. vandami has discrete anterior and posterior temporals, and anterior and posterior post-supralabials, as well as two postoculars, whereas Z. v. arenicola typically has the temporals and post-supralabials all fused into a single large shield, with a single elongated postocular (Broadley & Broadley 1997). While there is some variation to this head shield arrangement, most specimens of Z. v. arenicola exhibit considerable scale reduction (Broadley & Broadley 1997). |
