Figs 4-5

Helix (Cochlogena) citrinovitrea S. Moricand, 1836: 436 , pl. 2 fig. 19. – Breure, 1979: 135. – Neubert & Janssen, 2004: 205, pl. 17 fig. 208.

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

Label: “ Bahia ”, in Moricand’s handwriting [64617]; “ Bahia ”, in Brot’s handwriting [64616].

Dimensions: “Hauteur, 13 millim.; largeur, 10 millim.”; figured specimen herein H 16.0, D 11.7, W 4.4.

Type material: MHNG-INVE-64617, lectotype and 18 paralectotypes (ex Blanchet, Moricand coll.); 64616, four probable paralectotypes (ex Moricand, Brot coll.).

Remarks: Moricand did not state on how many specimens his description was based. Lot 64617 consists of one adult and many subadult specimens; the second lot (64616) from the Brot collection contains subadults only, but is herein considered as probable type material as uncertainty remains whether the specimens belonged to the original series or not. One specimen was found as ‘paratype’ [syntype] being registered MCZ 26283. Breure (1978: 235) has pointed out the disjunct distribution of this taxon (or, alternatively, the occurrence of morphologically convergent species; see Miquel, 1998); the designation of a lectotype (design. n.) should fixate this taxon until further morphological and molecular research has elucidated the relationships within the distribution range.

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