Genus Paradichromadora Dashchenko, 1991

Dashchenko (1991) established Paradichromadora when describing P. brevicula Dashchenko, 1991 associated with the sponge Adocia cinerea Grant, 1826 from Sea of Japan. There is no mention of Paradichromadora in the recent review of Tchesunov (2014) and we did not find any other reference or discussion about the status of this genus apart from the original description. Dashchenko (1991) states that the characteristic feature of this genus is the heterogeneous ornamentation of cuticle: smooth cuticle rings and those with simple dots interchange with cuticle rings with serrated strips of merged dots. According to the author Paradichromadora is most similar to Neochromadora and Dichromadora but it differs from the first by the “absence of rasp brims in the stoma”, no pharynx dilatation in the stoma region and presence of non-ornamented cuticle ring and from the second by more complicate ornamentation and weak development of pharyngeal bulb. In our opinion Paradichromadora description resembles Chromadorita which is a genus with large variation of cuticle ornamentation and bulb development among the species. It is probably a junior synonym of Chromadorita but until further studies and examination of the type species we prefer to consider it as a dubious genus.
