of the real lizards, family Lacertidae
Species:
Ichnotropis grandiceps BROADLEY, 1967
Common names:
Caprivi Rough-scaled Lizard (English) Caprivi Rauhschuppeneidechse (German)
Types:
Holotype: USNM 163989, an adult male. Paratypes: UM 16278 (male) and USNM 163990 (Juvenile). (UM = Umtali Museum, Rhodesia). Besides the type and paratypes, only 4 other specimens are known, collected by W.D. HAACKE and residing in the Transvaal Museum: DNMNH (= TM) 30822, DNMNH (= TM) 38309, DNMNH (= TM) 38310 and DNMNH (= TM) 38404.
Terra Typica:
25 miles west of Mohembo, Botswana, on the border of the Caprivi Strip, Namibia.
Taxonomic notes:
After the two specimens on which the first description is based, a further 4 specimens were reported by HAACKE (1970) from the north-east Namibian-Botswana border region. A discovery in 2022 provided the first genetic data (BREDA, R.V. van (2023)). Lacerta.de, 2025

An extensive Herpetofaunal survey of three under researched areas in North–eastern Namibia (all forming part of the Khaudum Ngamiland dispersal area) was conducted. The areas in question were the Nyae Nyae conservancy, Khaudum national park, and a small area of Mahango–Divundu, which borders the Okavango river approximately 75 km into the Caprivi strip. A preliminary checklist and desktop study of the areas was conducted based on known ranges and occurrences of Southern–African amphibian and reptile species, supplementing the survey. During the expedition 17 amphibian species representing 13 genera and 10 families, and 22 reptile species representing 19 genera and 12 families were encountered. Genetic sequencing of the 16S ribosomal gene was done for 20 specimens to confirm their identity. Phylogenetic trees of two species and ecological niche models of four species were created, supplementing scientific knowledge regarding the herpetofauna of this part of Namibia. This study provides the first record of adult specimens of an undescribed Pyxicephalus specie, as well as the first genetic data of Ichnotropis grandiceps.
