Pomacea thachi Huber in Thach, 2020 syn. nov.

= Ampullaria canaliculata Lamarck (1822) : 178.

= Pomacea thachi Thach (2020a) : 21; pl. 2, figs 17–24.

Holotype: NCSM 113634 (North Carolina Museum of Natural Sciences , Raleigh, North Carolina, United States of America).

Type locality: South of Attapeu Province, Laos [approx. 14.51°N, 106.84°E, Mekong River basin] .

Comments: This nominal species represents a junior synonym of Pomacea canaliculata (Lamarck, 1822) , the invasive Golden Apple snail, native to South America (Joshi et al. 2017; Ng et al. 2020). This species is a pest of rice and other aquatic plants (Halwart 1994; Carlsson and Lacoursiere 2005; Khay et al. 2018; Ng et al. 2020), and it could negatively affect native snail assemblages (Maldonado and Martín 2019). We establish the synonymy here because we want to avoid confusion among regional researchers, pest control managers, conservation biologists, and stakeholders in Laos and other Southeast Asian countries.
