Remarks

Africonus fuscoflavus is the most senior name applicable to a clade composed of individuals from a number of populations of cones distributed around Boa Vista and north Maio Island. Most of these populations had been introduced as separate species based upon their distinctive shell patterns. All of them share the same elongated radular tooth morphology observed in A. fuscoflavus ( Abalde et al. 2017a) . Representative

specimens of these taxa examined molecularly exhibit mitogenome sequences with little divergences with respect to that of A. fuscoflavus , and can be considered conspecific. Additionally, the type material of both A. cristinapessoae and A. gallopalvoi is consistent with the taxon A. fuscoflavus bearing a characteristic pattern of very fine brown axial lines. The recently described A. tarafensis was compared by the authors to A. delanoyae , which has similar shell pattern. However, the shell profile is even more consistent with that of A. fuscoflavus . We therefore consider A. tarafensis as another patterned form of A. fuscoflavus , morphologically similar to the population from Ponta Antónia (very close to Baía do Tarafe, in Derrubado area) included in our phylogeny, and initially identified A. cf. delanoyae ( Abalde et al. 2017a) . We can conclude that A. fuscoflavus is another example of a polymorphic species, comprising several well-defined forms with characteristic shell patterns, sharing the same radular morphology and mitogenome sequence. The distribution range for this species is now expanded and includes the islands of Boa Vista and Maio.
