Achromadora

The genus Achromadora Cobb, 1913 includes relatively small nematodes, distributed world-wide, who live mostly in terrestrial environments (mosses and soil) and to a lesser extent in freshwater biotopes. Nearly 30 species have been described so far, of which 17 species can be found in Europe. All Achromadora have a well annulated and punctated cuticle, 10 cephalic setae (6 + 4), a large spiral shaped amphid, a small stoma with a dorsal tooth and two smaller subventral teeth and an elongated conoid shaped tail usually ventrally curved and ending in a spinneret. Males are rare. All species are known as bacterio- and algaevorous.
