P. wahlbergi was originally described as Cryptoblepharus wahlbergi by Smith (1849) based on specimens from the “Country to the eastward of the Cape Colony,” later restricted to KwaZulu-Natal Province, South Africa, by FitzSimons (1937). Similar to all other members of the genus, the species has a complex taxonomic history, especially regarding its genetic allocation (for a review of its taxonomic and nomenclatural history see Schmitz et al. 2005 and Medina et al. 2016). The first records of this species for Angola were provided by Bocage (1895), who noted specimens collected by J.A.O. de Anchieta from Cahata and Caconda, in the higher elevation areas of Benguela and Huíla provinces, respectively. As he had done with P. cabindae, Bocage (1895) provided a detailed illustration of Angolan P. wahlbergi ( Fig. 7 View FIGURE 7 ). Boulenger (1905) referred to this species specimens collected “between Benguella and Bihé” [between what it is currently understood as Benguela and Bié provinces] by the British explorer William John Ansorge (1850–1913). These are the only published records of the species for Angola, although some other specimens assignable to the species were collected in the country during the twentieth century and deposited in the collections of Portuguese (IICT), North American (CAS, FMNH) and South African (TM) museums. More recently the species has been relocated in the country. Baptista et al. (2018) reported the presence of Panaspis sp. in theTundavala area. Butler et al. (2019) reported one specimen from Bicuar National Park, which they mistakenly labeled as P. aff. namibiana . Other specimens were recently collected by the authors LMPC and MPM in southeastern Bié Province.

Both Marques et al. (2018) and Branch et al. (2019) referred to the central Angolan populations of P. wahlbergi as P. aff. wahlbergi , suggesting doubts about its conspecificity with the nominotypical form, and even suggesting that the Angolan population may represent a different taxon ( Branch et al. 2019a). However, contrary to what Medina et al. (2016) demonstrated for the eastern African populations, where a high level of cryptic diversity exists, and to the suspicions of Marques et al. (2018) and Branch et al. (2019), our results unambiguously place the central Angolan population as conspecific with nominotypic wahlbergi . The presence in the country of additional undescribed wahlbergi -like lineages cannot be excluded, as Bittencourt-Silva (2019) recently reported the presence of one of these lineages (“ Panaspis sp. Katanga 2” sensu Medina et al. 2016) in northwestern Zambia, not far from the Angolan border. Specimens from Calombe-Luso, Moxico Province, (IICT 268–1959 and 276–1959) could potentially belong to this lineage as well. Further sampling in the eastern regions of the country is needed to address this possibility.

Diagnosis. Panaspis wahlbergi can be distinguished from other members of the genus occurring in Angola by the following combination of characteristics: 1) absence of supranasals; 2) ablepharine eye (as defined by Greer 1974); 3) frontoparietals fused; 4) dorsum coppery-brown, with a broad black lateral band; 5) absence of rows of light spots on the neck; 6) usually a presence of a white ventrolateral stripe, from supralabials to the groin; 7) 24 to 26 midbody scales rows ( Figs. 13–14 View FIGURE 13 View FIGURE 14 ).

Specimens examined. ANGOLA: Benguela Province: Cubal [-13.03333º, 14.25, 922 m] ( TM 39762 ) ; Kwanza-Sul Province: 10 miles SE of Quirimbo [-10.83998º, 14.308124º, 851 m] ( CAS 85966) ; Bié Province: near Mumbué [-13.85417º, 17.47044º, 1631 m] ( AMB 11675–11676 View Materials ) ; Chitau [-11.43333º, 17.15º, 1510 m] ( FMNH 74295 About FMNH , AMNH 48505 About AMNH ) ; Huíla Province: Caconda [-13.73333º, 15.06667º, 1675 m] ( NHM 1906.8.24.72); 19 miles NE of Lubango [-14.78503º, 13.730408º, 1691 m] ( CAS 85956) ; Lubango [-14.916667º, 13.5º, 1760 m] ( FMNH 74295 About FMNH ) ; Bicuar National Park [-15.1034º, 14.8311º, 1243 m] ( CAS 263401 About CAS ) .

Distribution. Medina et al. (2016) restricted to Mozambique and northeastern South Africa, but we here extend that distribution into south-central Angola. Historical records from Zimbabwe and Zambia might also represent true wahlbergi , potentially connecting the Angolan population to those of Mozambique and South Africa. However, this distribution requires further assessment, as other cryptic lineages may also be present, as evidenced by the recent discovery in northwestern Zambia of one of the Katangan cryptic lineages of wahlbergi by Bittencourt-Silva (2019). In Angola, P. wahlbergi is limited to the central and southern areas of the Angolan plateau, from Benguela Province to Bié ( Fig. 15 View FIGURE 15 ), but is most likely that the species also occurs in the neighboring areas of Moxico and Cuando-Cubango provinces.

Habitat and Natural History notes. The species is found in Miombo Woodlands, usually under leaf-litter, under rocks, or moving through grass ( Fig. 16 View FIGURE 16 ).
