Type material.

Lectotype (design. nov.) NHMUK 1903.7.1.3081/1 ( Sutcharit et al. 2019: fig. 10d). Paralectotypes NHMUK 1903.7.1.3081/2-5 (4 shells; Sutcharit et al. 2019: fig. 10e) from Abor Hills; NZSI (2 shells).

The type series of this species comprises lot "No. 3081 Brit. Mus." and two uncatalogued specimens in the Indian Museum. Without any explicit holotype designation or equivalent expression, all specimens are syntypes. However, only specimen lot "No. 3081 Brit. Mus." was mentioned in the “Type” paragraph, and one specimen from this lot was figured with the annotation “Type” in the plate caption. The author explicitly indicated that five specimens were examined, and type lot NHMUK 1903.7.1.3081 accordingly contains five specimens with a label in Godwin-Austen’s handwriting stating “Type”. We hereby designate the specimen from lot NHMUK 1903.7.1.3081 which is figured in the original description and in Sutcharit et al. (2019: fig. 10d) as the lectotype (NHMUK 1903.7.1.3081/1) to stabilize the name. This lectotype designation is based on the idea that Godwin-Austen (1915) selected this specimen lot as onomatophores.
