Type material.

Lectotype (design. nov.) NHMUK 1903.7.1.3105/1 ( Sutcharit et al. 2019: fig. 7d). Paralectotypes NHMUK 1903.7.1.3105/2 (1 shell) from Abor Hills; NHMUK 1903.7.1.3047 (2 shells; Sutcharit et al. 2019: fig. 7e) from Ponging; NZSI (2 shells).

The type series of this species comprises two specimen lots, "No. 3105 Brit. Mus." and "No. 3047 B.M.", and two uncatalogued specimens in the Indian Museum. Without any explicit holotype designation or equivalent expression, and given that the Register of Godwin-Austen Collection explicitly states that each lot contains two specimens (Fig. 7E, F ), all specimens in these lots are syntypes. However, only the figured specimen from lot "No. 3105 Brit. Mus." from Abor Hills was marked as “Type” in the plate caption (Fig. 1B ) and this lot is labelled as “Type” in Godwin-Austen’s handwriting (Fig. 4A ). In contrast, the figured specimen from lot "No. 3047 B.M." from Ponging was not marked as “Type” in the plate caption and this lot is labelled as “Typic” in Godwin-Austen’s handwriting (Fig. 4B ). Although, according to Art. 73.2., all the specimens of the type series are automatically syntypes and have equal status in being name-bearing types, we hereby designate the specimen from lot NHMUK 1903.7.1.3105 that is figured in Godwin-Austen (1915: pl. 39, fig. 4, 4a) and Sutcharit et al. (2019: fig. 7d) as the lectotype (NHMUK 1903.7.1.3105/1) to stabilize the name. This lectotype designation is based on the idea that Godwin-Austen (1915) selected this specimen lot as onomatophores and thus prevents any future attempt to designate a specimen from the other lots as the lectotype. The type locality of this taxon is restricted to "Abor Hills".
