REMARKS

Considered by Pease as a species of “ Hélictères ” (i.e. genus Helicteres , though the formal genus name was not used and it is therefore placed in square brackets above) in the subgenus Amastra (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. 1, figs 5, 5a) as a measured “Exemplaire figuré” (though, as is clear from the context, inadvertently as “ rugulosa ”) and also noted a “ paratype ” (they are now MNHN IM-2000-30837 and MNHN IM- 2000-30838, respectively). Johnson (1994: 24) referenced Fischer-Piette’s statement but credited him with having listed the “ Holotype ” as well as “ paratypes ” [sic], while also noting additional “ paratypes ” (MCZ 45162). Neither treatment constitutes a lectotype designation (see introductory text regarding lectotypes). The slightly taller, more globular of the two MNHN specimens appears to be that figured by Crosse and is therefore here designated as the lectotype. A label associated with the specimens indicates that they were received from Pease in 1869.
