Specimen.

Angola: Duque de Bragança : BMNH 1866.6.11.1 .

Comments.

The specimen was among the second batch of specimens collected by Bayão at Duque de Bragança, presented by Bocage to the British Museum in 1866 as “ Nº 1 - Stellio angolensis Bocage nov. sp. ” ( NHMA /DF/GüntherColl/16/1/110 ). Bocage (1866 a) recorded several specimens as Stellio nigricollis , stating that he had first thought they represented a new species he intended to name Stellio angolensis , but refrained from doing so after consulting Günther, who referred it to Agama nigricollis . Wagner et al. (2018) regarded angolensis to be a nomen nudum and suggested that Bocage’s reference to nigricollis was an error, also noted by Bocage himself ( Bocage 1895 a). We here confirm this observation, as in his letter dated 29 June 1866 Günther unambiguously wrote “ Stellio angolensis = Agama atricollis ”, and Bocage mentions also “ Agama atricollis ” in his response ( AHMB /CE/G79 , NHMA /DF/ZOO/200/1/185 ). The specimen presented to the British Museum was cited by Boulenger (1885 a) as Agama atricollis in his Catalogue of Lizards and more recently as a newly described species by Marques et al. (2022).
