[ Helicteres] ( Leptachatina) turgidula Pease, 1870: 89. Achatinella( Leptachatina) turgidula– Crosse 1876: 96, pl. 4, fig. 5]. CURRENT TAXONOMIC STATUS. — Leptachatininae, Leptachatina( Leptachatina) pachystoma( Pease, 1869), subspecies (see Cowie et al.1995: 128).
TYPE MATERIAL. — Lectotype(here designated) MNHNIM-2000- 30845. TYPELOCALITY. — “insula Kauai”.
REMARKS Considered by Pease as a species of “ Hélictères” (i.e. genus Helicter, though the formal genus name was not used and it is therefore placed in square brackets above) in the subgenus Leptachatina(see introductory text regarding species of Pease). The original description was not explicitly based on only a single specimen but neither does it imply the existence of syntypes. Fischer-Piette (1950: 149) listed the specimen illustrated by Crosse (1876: pl. 4, fig. 5) as the “ Holotype” and a label of the collection of the Journal de Conchyliologie, associated with this specimen and written at the time of Fischer-Piette, also says “ Holotype”. Johnson (1994: 26)simply referenced Fischer-Piette’s statement, while also noting additional “ paratypes” (MCZ 45182, MCZ 45183). Neither Fischer-Piette’s nor Johnson’s treatment constituted a lectotypedesignation (see introductory text regarding lectotypes). A label associated with the MNHN specimen indicates that it was received from Pease in 1869. The specimen matches Crosse’s illustrations, although the clear demarcation between the whitish lower part of the body whorl and the remainder of the shell is not so distinct in the actual specimen. It is here designated as the lectotype.
