Type material.

Lectotype NHMUK 1903.7.1.3145/1 ( Sutcharit et al. 2019: fig. 9b). Paralectotypes NHMUK 1903.7.1.3145/2-3 (2 shells; Sutcharit et al. 2019: fig. 9c) and NHMUK 1903.7.1.3147 (2 shells) from Sibbum, Abor Hills; NZSI M.6142 (1 shell) and NZSI M.6143 (1 shell) from Jeku, Abor Hills.

The type series of this species comprises four specimen lots. Only two specimen lots, "No. 6142-43 Ind. Mus.", which were explicitly stated to contain two specimens from "Jeku, Abor Hills", were mentioned in the “Type” paragraph, and one of these two specimens was figured and marked as “Type” in the plate caption. In contrast, the remaining lots were mentioned in the body of the text of subsequent paragraphs. This could mean that Godwin-Austen (1915) selected specimen lots "No. 6142-43 Ind. Mus." as onomatophores. However, without any explicit holotype designation or equivalent expression, all specimens of the type series are automatically syntypes with equal status in being name-bearing types. Thus, the designation of the lectotype from lot NHMUK 1903.7.1.3145, labelled as “Typical” in Godwin-Austen’s handwriting (Fig. 6C ), by Sutcharit et al. (2019) is valid under the Code, although this action contradicted the intention of the onomatophore designation by Godwin-Austen (1915). The type locality of this taxon is restricted to "Sibbum, Abor Hills".
