Material examined

Holotype (not examined)

The holotype is in CAS with catalog number 55454 according to the original publication. However, Coomans et al. (1986) stated that one of the paratypes ( CAS 61495, 10.7 × 6.0 mm) was deposited instead of the holotype, which was still missing in 1988 ( Filmer 2011). Current whereabouts of the holotype are unknown.

Paratype

SENEGAL • 1 spec., near NGor village; 14º43ʹ N, 17º33ʹ W; CAS 61495 .

Other material

SENEGAL • 1 spec., 22.0 mm; south of Dakar, Petite Côte , Yenne Tode ; L. Tamagnini leg.; GenBank mitochondrion, partial genome: MT240807 ; MNCN 15.05/90430 ( Fig. 10 G ) .

Geographical distribution

Dakar area, Senegal.

Conservation status in IUCN Red List

Endangered.

Remarks

This is a species very closely related to V. bruguieresi . In fact, in a previous phylogenetic analysis ( Abalde et al. 2017a), the mitogenome of one juvenile specimen initially identified as V. cf. echinophilus turned out to be identical in sequence to that of V. bruguieresi . However, the mitogenome of another specimen of V. echinophilus sequenced here was recovered as sister to that of V. bruguieresi , at a genetic distance consistent with a valid species ( Fig. 2 ).

Fig. 2. Phylogenetic relationships of West African cones and species delimitation. A time tree (relaxed molecular clock) was reconstructed following methods and calibrations in Abalde et al. (2017a). Dates are in million years. Bold names indicate new mitogenomes. A red line indicates the threshold (uncorrected p distance of 0.2%, based on the divergences between Africonus verdensis (Trovão, 1979) and its sister group and Varioconus guanche (Lauer, 1993) and its sister group) for species delimitation.
