Bastiania de Man, 1876

The genus Bastiania de Man, 1876 includes at present about 11 described species and occurs world-wide in semi-aquatic or terricolous habitats. They probably have a microbivorous feeding habit. Morphologically they are rather remarkable: they all have a very slender long body; a posteriorly situated amphid position and a 6 + 4 cephalic setae arrangement. In Europe four Bastiania species have been found so far. Although this genus is widely distributed in Europe it is not a common nematode genus. Bastiania species reproduce sexually. For identification to species level, male are also important.
