Type localities.

“ Bukit Chintamani, Pahang ” (Bukit Cinta Manis), Malaysia (H. terae); “ Bukit Charas, near Kuantan, Pahang ”, Malaysia (H. megaphonum); “ Bukit Takun, Kanching, Selangor ”, Malaysia (H. perigyra).

Differential diagnosis.

This species differs from H. elephas by its less detached and protruding last whorl as well as the much more conical shell.

Distribution.

This species is known from Pahang and Selangor provinces in Peninsular Malaysia.

Remarks.

Hypselostoma megaphonum and H. perigyra are synonymised with this species based on the following: i) all three species share the same arrangement and morphology of apertural barriers; ii) umbilici of all three species are equally narrow (with very slight variability which can be considered intraspecific); iii) all three species have the same narrow and sharp peripheral keel and iv) all three species are of similar size and distributed geographically close. All differences mentioned by van Benthem Jutting (1950) in the original description (last whorl inflation level, umbilicus width and apertural barrier strength) are recognised as intraspecific variability. Hypselostoma megaphonum can be interpreted as an intermediary form between H. terae and H. perigyra based on the following characters: i) last whorl more inflated than in H. terae but less than in H. perigyra; ii) apertural barriers stronger than in H. terae but weaker than in H. perigyra; iii) umbilicus wider than in H. terae but narrower than in H. perigyra.
