Pupa pascuana Raines, 2003 View in CoL

( Fig. 16B View FIGURE 16 )

Pupa pascuana Raines, 2003: 52 View in CoL , figs 1–2. Type locality: off the western coast of Tahai , Easter Island.

Type material. Holotype, dry shell, 11 mm long ( LACM 2954 About LACM ).

External morphology. Live animal unknown. Shell solid, narrow, very elongate, widest at midlengh, with slightly convex, nearly parallel sides, rounded to elongate anterior end ( Fig. 16B View FIGURE 16 ). Body whorl large, about 3/4 of total length. Spire conical, with 5 whorls. Suture channeled. Aperture elongate, wider anteriorly, narrowing gradually towards posterior end, ending at 4/5 of the posterior end of first whorl. Columellar margin thickened, slightly oblique, with large, channeled anterior fold starting at anterior end of aperture; minute, simple posterior fold located at aperture mid-length, separated from anterior fold by wide gap. Protoconch globose, 0.1 mm in diameter, with ~1.5 whorls. Sculpture composed of numerous punctuated spiral grooves. Punctuations conspicuous, irregular, oval, situated next to each other, often fused together, within each groove. Grooves separated by gaps slightly wider than grooves. Shell color whitish to pale cream with irregular orange spots all over the surface.

Geographic range. Possibly endemic to Easter Island ( Raines, 2003; present paper).

Remarks. Raines (2003) introduced the name Pupa pascuana Raines, 2003 based on several shells collected on Easter Island. Based on the examination of the holotype (LACM 2954; Fig. 16B View FIGURE 16 ) it appears to be distinct from other species examined herein and probably constitutes an endemic species to Easter Island, but this needs to be confirmed with molecular and anatomical data.
