|Diagnosis||Diagnosis. External morphology, skull anatomy and molecular data (see below) clearly supports the posi- tion within the genus Atractaspis. The new species can be only mistaken morphologically with species from Laurent’s (1950) section ‘D’, his reticulata-group. In particular it differs from all other species of the genus, except A. reticulata and A. corpulenta (including the West African A. c. leucura), by the fusion of the 2nd infralabial with the inframaxillary. From A. corpulenta it differs by a much higher ventral count (276–288 vs 178–208), lower number of dorsal scale rows at mid- body (19 vs 23–29), divided anal plate and subcaudals, and the absence of a white colored tail tip (present in A. c. leucura); from A. reticulata it can be distin- guished by a lower ventral count (276–288 vs 304– 370), and 19 (the paratype has mostly 19 scale rows, but 20 at midbody) dorsal scales rows at midbody (19 scale rows present in the A. reticulata holotype, oth- er vouchers having 21–23 rows) (Table 1). The new species further differs from A. corpulenta by a more slender body and from A. reticulata by a longer tail compared to body length.|
|Etymology||Named after William Roy “Bill” Branch (1946–2018), for his outstanding contributions to African herpetology. See Wagner 2019 for biographical notes.|
