Remarks

This taxon was initially introduced as a subspecies of A. grahami   . Despite superficial resemblance in shell morphology, A. longilineus   is a separate species endemic to Sal Island, only distantly related to A. grahami   . Although the type locality for A. longilineus   was not specifically mentioned in the original description, its distribution range was stated to be along the east coast of Sal Island, with another population in the north of the island. Several representative specimens of recently named taxa described from the east coast of Sal Island exhibit mitogenome sequences almost identical to that of A. longilineus   , and are therefore considered synonyms (forms) of this species. The species A. nelsonandradoi   was compared in the original description to the very variable A. cagarralensis   , which is a synonym (form) of A. longilineus ( Abalde et al. 2017a)   . We propose to consider that A. nelsonandradoi   represents merely a northern population of the latter. On the other hand, A. minimus   likely is a juvenile of A. longilineus   . Besides, the name Africonus minimus Cossignani & Fiadeiro, 2015b   most likely is invalid under ICZN articles 57.3 and 59.1, as it is a junior secondary homonym of Conus minimus Linnaeus, 1758   , Conus minimus Hwass in Bruguière, 1792   and Conus minimus d’Archiac, 1843   .
