Conus trencarti Nolf & Verstraeten, 2008: 1 , pls 1–2.

Material examined

Holotype

SENEGAL • 26.3 mm; Pointe des Almadies ; 20 m depth; MNHN IM-2000-21455 ( Fig. 11K View Fig ).

Other material

SENEGAL • 1 spec.; Pointe des Almadies ; A. Trencart leg.; GenBank mitochondrion, partial genome: MT240815 View Materials ; MNCN 15.05/90433 .

Geographical distribution

Dakar area, Senegal.

Conservation status in IUCN Red List

Near threatened.

Remarks

This is another member of the V. guinaicus clade, with a close phenotypical resemblance to V. guinaicus form pineaui . The sequence divergence of the mitogenome of one individual from the type locality suggests that this is a valid species, sister to V. guanche and V. unifasciatus ( Fig. 2 View Fig ). At variance with most other species of Varioconus from Senegal, V. trencarti has a relatively deep-water habitat, between 20 and 40 m, and a restricted distribution range around Pointe des Almadies, Dakar.

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.
