Distribution and ecology. Kurzia longirostris is distributed in the tropical and subtropical regions of Australia, Asia, Africa and South America ( Rajapaksa & Fernando 1986b; Kotov et al. 2012, 2013 a, 2013b; Lopez et al. 2017). In South and Southeast Asia, it is more common than K. brevilabris , and in East Asia, K. longirostris penetrates as far as South Korea ( Rajapaksa & Fernando 1986b; Michael & Sharma 1988; Sanoamuang 1998; Hudec 2000; Maiphae et al. 2005, 2008; Tanaka & Ohtaka 2010; Rane 2011; Kotov et al. 2012, 2013b; Chatterjee et al. 2013; Korovchinsky 2013; Ji et al. 2015; Sinev & Yusoff 2015, 2018; Sinev et al. 2015; Sinev 2016; Lopez et al. 2017; Sharma & Sharma 2017; Tiang-Nga et al. 2020; Choedchim & Maiphae 2023; Dadykin et al. 2023). Sinev (2016) notes that some previous records of K. longirostris in Southeast Asia actually belong to K. brevilabris . In Vietnam, K. longirostris is well-known and widespread ( Dang et al. 1980, 2002; Dang & Ho 2001; Sinev & Korovchinsky 2013; Gusakov et al. 2014; Phan et al. 2015).

Kurzia longirostris is a phytophilous littoral chydorid, dwelling among bottom sediments and aquatic plants. It is found in a wide variety of water bodies and habitats, from lakes, reservoirs, rivers and streams to small temporary pools ( Sanoamuang 1998; Tanaka & Ohtaka 2010; Sinev & Korovchinsky 2013; Phan et al. 2015; Sinev & Yusoff 2015; Sinev et al. 2015; Sinev 2016; Lopez et al. 2017; Gogoi et al. 2018; Korovchinsky et al. 2021b; Choedchim & Maiphae 2023). During our research, several individuals of this species were found in a stagnant section of a forest stream (see Appendix 1).
