Agama cf. schacki Mertens, 1938

Specimens.

Angola: Duque de Bragança : BMNH 1866.6.11.2 , Caconda : BMNH 1893.12.27.3 , Quindumbo : BMNH 1893.12.27.4 .

Comments.

Two adult males ( BMNH 1866.6.11.2 , BMNH 1893.12.27.4 ) and one female ( BMNH 1866.6.11.2 ) were sent from the Lisbon Museum. The specimen from Duque de Bragança was sent in 1866 as “ Agama sp. ? ” ( NHMA /DF/GüntherColl/16/1/110 ) and was noted by Günther as “ closely allied to Agama occipitalis , but has somewhat smaller scales ” ( AHMB /CE/G79 ), leading Bocage (1866 a) to conservatively refer additional material collected by Bayão to “ Agama occipitalis Gray. var.? ”. This specimen was later cited by Boulenger (1885 a) as Agama planiceps . Butler (2020) validated the specific status of Agama schacki and identified cryptic diversity associated with this taxon. While the specimen from Quindumbo likely represents typical Agama schacki , those from Caconda and Duque de Bragança belong to two additional distinct lineages ( Butler 2020).
