The nematodes Paradichromadora brevicula gen. et sp.n. were found in
the Adocia cinerea sponge. They resemble most of all representatives
of the genera Neochromadora Micoletzky, 1924 and Dichromadora Kreis,
1929. They differ from the former by the absence of rasp brims in the
stoma and no pharynx dilatation in the stoma region, and by the
presence of non-ornamented cuticle rings; from the latter - by a more
complicated cuticle ornamentation and a weekly developed cardial bulb.
