Type locality.
"Sibbum, Abor Hills".
Material examined.
Sibbum, Abor Hills, coll. Oakes, NHMUK 1903.7.1.3143 (holotype [single specimen mentioned in the original description]).
Remarks.
In the original description the subgeneric name Raptomphalus is not noted. However, the species is introduced after Alycaeus (Raptomphalus) magnificus , and the characteristically keeled umbilicus is similar to this species.
Protoconch elevated, spirally striated; R1 regularly ribbed, with recognisable spiral striae; R2 moderately long, with dense ribs, but their fine structure could not be examined due to the weathered condition of the holotype.
