Taxonomic and distributional notes: Dispholidus typus is often cited as having been described in 1829 (e.g., FitzSimons 1962) in The Zoological Journal, however, the description first appeared one year earlier in the South African Commercial Advertiser in a short paper that has been reprinted by Ulber (2003) and Branch and Bauer (2005). FitzSimons’ restricted type locality is derived from the stated type locality of Bucephalus viridis Smith, 1841 , a subjective junior synonym of B. typus Smith, 1828 . Four subspecies: D. t. typus , D. t. viridis Smith, 1828 , D. t. kivuensis Laurent, 1955 and D. t. punctatus Laurent, 1955 were recognised in the past. Preliminary genetic analyses carried out by Eimermacher (2012) indicate that multiple distinct lineages may be present, some of which should be resurrected and elevated to species status, including D. t. punctatus Laurent, 1955 from “Dund,” Angola. Eimermacher and Broadley (in prep.) are currently undertaking a detailed revision of the genus. All Angolan material should be reevaluated in order to determine where species boundaries lie. Eimermacher’s (2012) sampling was sparse in southwestern Africa, but his data suggested that central Namibian material was referable to to D. t. viridis ( Smith, 1838) . If this form also reaches southern Angola and is likely valid, as suggested by Eimermacher (2012), then it, rather than D. t. typus , would be the widespread Boomslang in Angola. However, as no published records from Angola have previously been referred to D. t. viridis , we continue to use the nominotypical epithet for Angolan specimens pending relevant genetic data.

Taxonomic and distributional notes: Although Broadley and Wallach (2002) considered punctatus a synonym of D. typus, Eimermacher (2012) indicated that multiple distinct lineages of boomslang should be probably be resurrected and elevated to species status, including D. t. punctatus . On this basis we list this form as a distinct taxon, but retain its subspecific status pending further data. All Angolan material should be reevaluated in order to determine where species boundaries lie. It seems likely on biogeographic grounds that some of the more southern and western records previously attributed to D. t. punctatus may, in fact, belong to the nominotypical form or to D. t. viridis (see Notes und Dispholidus typus typus ).
