Distribution and ecology. This is a recently described rare species from Indochina, probably endemic to Southeast Asia. To date, it has only been found in Thailand, Laos and Vietnam ( Sinev & Kotov 2012; Korovchinsky 2013; Kotov et al. 2013a, b; Sinev & Korovchinsky 2013; Zhdanova 2014; Sinev 2016; Choedchim & Maiphae 2023; present study).

The species lifestyle and ecology are little known. Most likely, this chydorid prefers running water bodies (rivers and streams) ( Sinev & Kotov 2012; Sinev & Korovchinsky 2013; Sinev 2016), although it occurs in lakes and reservoirs too ( Zhdanova 2014; Choedchim & Maiphae 2023). In our material, A. sanoamuangae was especially abundant in qualitative samples from the open and overgrown littoral of a small reservoir (Nos. 25, 26; see Appendix 1).
