Type locality.

“ South of Puttabanpot Temple, Pajoh Village, Nawang District, Nongbualumpoo Province, 17°19'1"N, 102°7'3"E, 320 meters elevation, Thailand ”.

Differential diagnosis.

This species is by the level of its last whorl ascension similar to H. kohrin and H. diarmaidi . It can be separated from H. kohrin and H. diarmaidi by the absence of typical spiral striation on the shell which is present in the latter two.

Distribution.

This species is known only from the type locality.

Remarks.

In H. surakiti , we could observe some irregular and weak spiral striae on the last whorl although they are not in form of typical raised spiral striae.
