Pterocyclos brahmakundensis Godwin-Austen, 1915 Pterocyclos brahmakundensis Godwin-Austen, 1915: 499, 500, with text figure 1. Sutcharit et al. 2019 : 14, fig. 3d, e. Type material. Lectotype (design. nov.) NHMUK 1903.7.1.713/1 ( Sutcharit et al. 2019 : fig. 3d). Paralectotypes NHMUK 1903.7.1.713/2-3 (2 shells; Sutcharit et al. 2019 : fig. 3e) from Brahmakund, Eastern Assam. Godwin-Austen (1915) explicitly stated that three specimens of this taxon were obtained, and the type specimen lot number was "No. 713 B.M." Without any explicit holotype designation or equivalent expression, these three specimens are syntypes. The specimen figured in Sutcharit et al. (2019 : fig. 3d) that corresponds to the text figure and the shell measurements given in the original description is hereby designated as the lectotype (NHMUK 1903.7.1.713/1) to stabilize the name.
