Cerithiopsis capixaba Figueira & Pimenta, 2008: 77 , figs. 24–28

Cerithiopsis capixaba : Rolán et al. (2012: 7, fig. 19).

Type material. Holotype: IBUFRJ 15221 [*].

Type locality. Brazil, off Espírito Santo state (20°38ʹS, 40°00ʹW, 33 m) .

Material examined. The holotype and: Brazil, -- Rio de Janeiro state: HAB 16 sta. H3: MNRJ 16553 [2*]; HAB 11 sta. G3: MNRJ 16552 [4*p]; HAB 13 sta. H4: MNRJ 16554 [1*]; HAB 11 sta. B4: MNRJ 16550 [2*p]; HAB 11 sta. B5: MNRJ 16551 [1*]; 22°42ʹS, 40°40ʹW, 110–120 m, 19/ix 2003: MNRJ 31356 [5*]; 22°42ʹS, 40°40ʹW, iii/ 2007: MNRJ 32947 [1*p], MNRJ 31360 [2*], MNRJ 31714 [1*]; 23°04ʹS, 40°59ʹW, 17/xii/2004: MNRJ 33007 [5*p].

Remarks. The teleoconch of the material studied can reach up to eight whorls and the shell reaches 4.0 mm long vs. 3.0 mm long and seven teleoconch whorls in the type material ( Figueira & Pimenta 2008). In addition, the last two protoconch whorls show a spiral microsculpture between the axial ribs ( Fig. 19H ), which was not detected by Figueira & Pimenta (2008), who indicated such supposed absence of microsculpture in C. capixaba as a difference to Cerithiopsis ara Dall & Bartsch, 1911 . However, both species have other substantial differences ( Figueira & Pimenta 2008), in addition to the white band in the adapical spiral cord of teleoconch (typical of C. ara ), not present in C. capixaba ( Fig. 19A–B ).

Geographic and bathymetric distribution. Only known from type locality and surrounding areas, in the Warm Temperate Southwestern Atlantic Province (Espírito Santo and Rio de Janeiro states); a single record from the Warm Temperate Southwestern Atlantic Province (São Paulo state) was provided by Figueira & Pimenta (2008). From 33 m to 135 m ( Figueira & Pimenta 2008).
