Helix (Cochlogena) pseudosuccinea S. Moricand, 1836: 435 , pl. 2 fig. 18. – Neubert & Janssen, 2004: 225, pl. 17 fig. 206.

Type locality: [ Brazil] “environs de Bahia [Salvador]”.

Label: “ Bahia ”, in Moricand’s handwriting.

Dimensions: “Hauteur, 21 mill.; largeur, 10 mill.”; figured specimen herein H 21.8, D 9.81, W 4.9.

Type material: MHNG-INVE-64619 , 42 (2 + 7 + 33) syntypes (ex Blanchet, Moricand coll.).

Remarks: Moricand did not state on how many specimens his description was based, but from his text it is clear that at first he had only a juvenile shell, and only later he received “un très grand nombre d’individus”, but remarked “pendant deux années, M. Blanchet n’eût pas rencontré quelques adultes”. Three lots in MHNG are considered as type material, one without any label and consisting of 33 mostly subadult specimens, one with only a taxon label and consisting of seven subadult and juvenile specimens, and one lot of two specimens with a locality and taxon label. One additional syntype is present in the MCZ collection, registered as MCZ 26190 as ‘paratype’ [syntype]. The current systematic position follows Simone (2006).

Current systematic position: Simpulopsidae , Simpulopsis (Eudioptus) pseudosuccinea (S. Moricand, 1836) .
