Holotype: NCSM 113628 (North Carolina Museum of Natural Sciences , Raleigh, North Carolina, United States of America).

Type locality: Battambang, Cambodia [approx. 13.1°N, 103.2°E, Tonlé Sap Lake – Mekong River basin] .

Comments: This nominal species is a conchological form of Pila pesmei (Morlet, 1889) that was described from Cambodia (Morlet 1899; Brandt 1974; Ng et al. 2020). Regrettably, the latter species was overlooked in the protologue (Thach 2020a). The deep black periostracum of the type shells should reflect an exposition in organic-rich anaerobic sediments of a highly eutrophic water body, i.e. rice fields, where the type series was collected (Thach 2020a).
