Nesiodostomia
sp. #1
 
Nesiodostomia sp. #1: shell
Maximum size:  3.5 mm shell length.

Identification:  The shell of this species is straight sided and slender. It may be distinguished from the shell of  Nesiodostomia quarta by its larger protoconch and straighter sides. Some shells have similar protoconchs but are somewhat more inflated. (see photo).

Natural history:  Shells of  Nesiodostomia sp. #1 are moderately common in beach drift. Live animals are occasionally found in shallow rocky habitats.

Distribution:  Maui.

Taxonomic notes:  This species is listed in Severns, 2011 as Eulimella sp. 2. There's some possibility that the more inflated shells may be a separate species. However, they appear to intergrade sufficiently to suggest lumping.
