conoideum . Cerithium (Pithocerithium) . Karlov, 1932 [non Lamarck, 1804]

see Lampanella maeotica ( Karlov, 1932)

* Cerithium (Pithocer[ithium].) conoideum n. sp. — Karlov 1932: 74 [non Lamarck, 1804].

Type material. Lectotype designated herein: specimen illustrated in Karlov (1932: pl. 1, figs 37–40), SL: 10 mm, MD: 5.5 mm; National Mining University , Dnipropetrovsk ( Ukraine).

Type locality. Mount Mitridat in Kerch ( Russia) .

Stratigraphy. Late Miocene, early Maeotian.

Discussion. This species was described by Karlov (1932: 74) as Cerithium conoideum , which is preoccupied by Lamarck (1804). In the German summary and in the plate captions, Karlov (1932: 80) described the same species as Cerithium formosum , which is preoccupied by Zekeli (1852). We consider this morph to be a synonym of Lampanella maeotica ( Karlov, 1932) , with which it co-occurs. Therefore, no replacement name is needed.

Eastern Paratethys. Early Maeotian: Crimea: Kerch (Mount Mitridat) ( Russia).
