Helix (Cochlogena) coxeirana S. Moricand, 1836: 433 , pl. 2 figs 7-11. – Neubert & Janssen, 2004: 206, pl. 17 fig. 216.

Helix caxoeirana S. Moricand, 1841: 59 [emendation].

Leiostracus (Leiostracus) coxeiranus View in CoL . – Köhler, 2007: 154, fig. 140.

Type locality: [ Brazil] “Caxoeira, dans la province de Bahia et dans les bois de St.-Gonzales” .

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

Dimensions: “Hauteur, 33 mill.; largeur, 15 mill.”; largest figured specimen herein H 33.0, D 15.2, W 7.2.

Type material: MHNG-INVE-64548, five syntypes; 25410, two syntypes; 25416, one syntype (ex Blanchet , Moricand coll.) .

Remarks: Moricand evidently had several specimens at hand, as he recognized five different colour variations (trizona, dizona, nigrescens, purpurascens, unicolor ), partly on the basis of subadult or juvenile specimens. These names are considered as infrasubspecific, were not adopted as valid names before 1985, and are thus unavailable ( Lingafelter & Yanega, 2012). Type material of this taxon is also present in ZMB ( Köhler, 2007) and SMF ( Neubert & Janssen, 2004).

Current systematic position: Simpulopsidae , Leiostracus coxeiranus (S. Moricand, 1836) .
