Family Bastianiidae de Coninck, 1935

12. * Bastiania parexilis de Coninck, 1935 — {27, 29} (0, 7, 0, 0; 3)

Population structure and abundance. At site 27—14 females (including one with egg), two males and a single juvenile (18x10 3/m2), at site 29 (qualitative sample)—alone female.

Ecology and distribution. Amphibiont. Occurs both in terrestrial and aquatic biotopes ( Jacobs 1984). Rare species, apparently, until recently noted only in two regions: Central Africa ( Zaire) and in Russian Far East ( Jacobs 1984; Andrássy 1991).

Remarks. In the fullest identification handbook to date on free-living nematodes of Vietnam ( Nguyen 2007), the genus Bastiania is not listed. At the same time, B. exilis Cobb, 1914 was found in one river in the north ( Nguyen & Nguyen, 2005). The same species was also reported from Hainan Island ( China), situated close to Vietnam ( Wu & Liang 2000).
