Cretadmete Blagovetshenskiy & Shumilkin 2006

Description

Genus Cretadmete Blagovetshenskiy & Shumilkin, 2006

Type species. Cretadmete neglecta Blagovetshenskiy & Shumilkin, 2006 by OD; Upper Hauterivian (Early Cretaceous) of Slantsevyi Rudnik, Ulyanovsk Region, Russia.

Remarks. Blagovetshenskiy & Shumilkin (2006) placed Cretadmete in Admetidae Troschel, 1865. The type species of Admete, A. viridula (Fabricius, 1780), possesses two columellar folds and a paucispiral protoconch (Harasewych & Petit 1986) while Cretadmete has no columellar folds or plaits and a multispiral protoconch (Blagovetshenskiy & Shumilkin 2006), which is very similar to protoconchs of Purpurinidae (Guzhov 2004; Kaim 2004). Purpurindae have been suspected for a long time to be a sister group (Taylor et al. 1980) or stem group (Kaim 2004) of Neogastropoda and recently they have been treated as a family of Neogastropoda with uncertain superfamilial position (Bouchet et al. in press).
