Ilyocryptus thailandensis Kotov et Sanoamuang, 2004

8. * Ilyocryptus thailandensis Kotov et Sanoamuang, 2004

Localities and specimens found: 62 − 1♀ ov, 1j; 67 − 13♀, 7♀ ov, 6♀ em, 9j.

Distribution and ecology. This is a rare species, perhaps an endemic to Southeast Asia. It was described from Thailand ( Kotov & Sanoamuang 2004b), and later this species was also recorded in Laos ( Kotov et al. 2013b). In Vietnam, I. thailandensis was recently discovered during the present studies of the bottom meiofauna ( Gusakov et al. 2024; Kotov et al. 2024).

The species lifestyle and ecology are unstudied. Obviously, they are similar to those in other congeners. Hitherto, I. thailandensis has been found in a permanent pond, puddle and peat swamp ( Kotov & Sanoamuang 2004b; Kotov & Štifter 2006; Choedchim & Maiphae 2023). In Vietnam, we registered it in two temporary water bodies: a small floodplain forest lake and a roadside pool (see Appendix 1). In the second habitat, the species was relatively abundant.
