Taxonavigation

Ordo: Sorbeoconcha
Familia: Buccinidae
Genus: Jerrybuccinum

Name

Jerrybuccinum explorator (Fraussen & Sellanes, 2008) comb. n. – Wikispecies link – Pensoft Profile

• Kryptos explorator Fraussen & Sellanes, 2008: 102-104, figs 5–6, 16–25.

Type material

Holotype in MNHNCL-5866, two paratypes in MNHNCL-5867-5868, two paratypes in KF-5180-5181 and a paratype in MNHN-9961.

Type locality

South-central Chile, R/V Vidal Gormáz (SeepOx Cruise, AGT 6-7, 09/02/2006), CMSA, northwest of the Bay of Concepción, 36°20'97S, 73°44'86W, 850 m.

Remarks

This species was tentatively placed in the genus Kryptos (Fraussen and Sellanes 2008) based on similarities in sculpture and radula and to prevent the description of a monotypic genus. The radula is identical to the radula of Jerrybuccinum malvinense. It is characterised by a monocuspid central tooth with quadrangular base and by tricuspid lateral teeth that have a broad base prolonged with a basal projection. The shape, the axial and spiral sculpture of the shell and the shape of the operculum are similar. We hereby assign this species to Jerrybuccinum.
