Comment	Limb morphology: Limbless. Type not in South Africa fide SAMA catalog (Anonymous 1958). Synonymy: Based on DNA sequence data, DANIELS et al. (2005) suggest that both A. m. orientalis and A. p. tasmani are invalid taxonomic designations, and should be regarded as junior synonyms of A. m. meleagris. LAMB et al. (2010) “regard these two taxa as being questionably distinct. Both names were proposed in the same work (Hewitt 1937), and we select the former, which has page priority as the senior synonym. Further work will be necessary to resolve these taxonomic ramifications.” Daniels et al. (2005, 2009) noted A. m. meleagris is paraphyletic at several levels, and a form they designated as A. m. orientalis “lineicauda morph” is also paraphyletic. LAMB et al. 2010 “recognize A. meleagris, A. lineicauda, and A. orientalis/A. tasmani as genetically distinct, morphologically diagnosable units”, however, note that their relationships are not clear. This uncertainty was maintained by Bauer in Bates et al. 2014: 244 although he listed lineicauda as valid species. Hybridization: Broadley and Greer (1969) noted on the basis of aberrant specimens that A. p. tasmani and A. m. orientalis may hybridize where they occur in sympatry.
