Type material examined.

Syntypes of Rhaphaulus perakensis NHMUK 1897.3.15.41-2 (2 shells; Fig. 13C ) from Larut, Perak.

Diagnosis.

Shell elongate ovate; body whorls slightly bulging. Tube cylindrical, pointing diagonally downward and backward.

Differential diagnosis.

Rhaphaulus perakensis can be distinguished from all other species from mainland Southeast Asia by a cylindrical tube pointing diagonally downward and backward.

Distribution.

Northern Peninsular Malaysia and southern Thailand ( Maassen 2001; Páll-Gergely et al. 2014).

Remarks.

No material of this species was found during this survey. Maassen (2001) treated R. perakensis jalorensis as a junior subjective synonym of R. p. perakensis without apparent reason, whereas Páll-Gergely et al. (2014) listed this subspecies as a valid species following the opinion of Sykes (1903).
