Genus Chromadorina Filipjev, 1918 

This genus was proposed by Filipjev (1918) who designated C. obtusa Filipjev, 1918  as the type species; it was later revised by Wieser (1954). In the latter review, Heterochromadora Wieser, 1951  was synomized with Chromadorina  and two species belonging to the former genus were transferred [C. cervix ( Wieser, 1951) and C. granulopigmentata ( Wieser, 1951)  ]. In the same review several other species were also transferred from Spiliphera  [ C. rognoeensis (Allgén, 1932)  ], Chromadorita  [ C. longisetosa ( De Coninck & Schuurmans Stekhoven, 1933)  ], Prochromadora  [ C. macropunctata ( Wieser, 1954)  ], Prochromadorella  [ C. astacicola ( Schneider, 1932)  and C. ocellata (Paramonov, 1929)  ] and Chromadora  [ C. armata ( Allgén, 1933)  , C. bergensis (Allgén, 1932)  , C. bioculata (Schultze in Carus, 1857)  , C. erythrophtalma ( Schneider, 1906)  , C. germanica ( Bütschli, 1874)  , C. pacifica ( Allgén, 1947)  , C. parobtusa ( Allgén, 1947)  and C. viridis ( Linstow, 1876)  ]. However, C. parobtusa  and C. pacifica  were considered as synonyms of C. laeta (de Man, 1876)  , and C. ocellata  was suggested to be a synonym of C. bioculata  . C. cylindricauda (Allgén, 1928)  was regarded as a dubious species by Wieser (1954) and here we consider it as inquirendum since its original description is poor and is based on a single female. A key based on male characters was also developed by Wieser (1954), but fourteen of the current valid species were described later ( C. bercziki Andrássy, 1962  ; C. demani Inglis, 1962  ; C. epidemos Hopper & Meyers, 1967  ; C. hiromii Kito & Nakamura, 2001  ; C. incurvata Wieser, 1956  ; C. inversa Wieser, 1955  ; C. longispiculum Pastor de Ward, 1985  ; C. majae Wieser, 1968  ; C. metulata Aissa & Vitiello, 1977  ; C. micoletzkyi Inglis, 1962  ; C. nuda Wieser, 1954  ; C. paradoxa Timm, 1961  ; C. salina Belogurov, 1978  and C. supralitoralis Lorenzen, 1969  ). In the description of C. demani, Inglis (1962)  argued concerning the validity of C. laeta  , therefore a new name for C. laeta sensu Micoletzky, 1924  was proposed (therein called C. micoletzkyi Inglis, 1962  ) and C. laeta sensu Daday, 1901  , C. laeta sensu de Man, 1876  and C. laeta sensu Wieser, 1954  were considered species inquirenda due to the poor description provided by all these authors. C. pacifica  and C. parobtusa  are not considered as valid species here as they were previously indicated as possible synonyms of C. laeta ( Wieser 1954)  . Finally, the most recently described species in this genus was C. hiromii  by Kito & Nakamura (2001), but they pointed out to the similarity of this species to C. inversa  , which was originally described by Wieser (1955) based on a single female from the Sea of Japan and subsequently re-described based on both genders from Mediterranean ( Wieser 1956). For Kito & Nakamura (2001), there is an uncertainty concerning conspecific specimens from Mediterranean and Japan and they suggested that topotypic males of C. inversa  should be compared to C. hiromii  . Here, we consider both species ( C. inversa  and C. hiromii  ) as valid until further studies are done.

Diagnosis (modified from Tchesunov 2014): Homogeneous punctated cuticle with transverse rows of dots and without lateral differentiation. Amphideal fovea, when visible, transverse slit-like. Buccal cavity with three (sub)equal solid teeth. Ocelli may be present. Cup-shaped precloacal supplements usually present. Tail elongateconoid with glands and well-developed spinneret. It is largely a marine genus (23 species) with only four limnetic species ( C. astacicola  , C. bercziki  , C. bioculata  and C. viridis  ). C. erythrophthalma  , C. germanica  and C. laeta  live in marine habitats but occasionally can be found in island body waters.

Number of valid species: 27
