Genus Prochromadorella Micoletzky, 1924
This is the most species rich genus within Chromadorinae . It was erected to accommodate some Chromadora species [ P. arabica ( Cobb, 1890) , P. mediterranea ( Micoletzky, 1922) , P. neapolitana (de Man, 1876) and P. sumatrana ] showing a dissimilar cuticular pattern along the body (i. e. heterogenous cuticle). P. neapolitana was designated as the type species. Wieser (1951) described P. macroocellata and transferred P. norwegica (Allgén, 1932) (misspelled as P. norvegica ) and P. paramucrodonta (Allgén, 1929) , both from Chromadora and P. obtusidens ( Schuurmans Stekhoven & Adam, 1931) from Chromadorita to this genus. However, later Wieser (1954) indicated the doubtful position of P. macroocellata because the description was based on a female specimen. In his review, Wieser (1954) assumed that the taxonomic status of some species was dubious due to the insufficient descriptions (diagnoses and figures) of the buccal cavity, but nevertheless some species were transferred to this genus: P. acridentata ( Schulz, 1932) previously described as Chromadorella ; P. affinis ( Allgén, 1930) , P. ambigua ( Ditlevsen, 1928) , P. cobbiana , P. conicaudata (Allgén, 1927) , P. ditlevseni (de Man, 1922) and P. maculata ( Ditlevsen, 1918) (all described as Chromadora ); P. kryptospiculum ( Allgén, 1942) and P. ungulidentata (Allgén, 1932) (both described as Spiliphera ); P. antarctica ( Cobb, 1914) and P. quinquepapillata ( Schuurmans Stekhoven, 1935) previously described as Euchromadora and Neochromadora , respectively. P. sumatrana and P. affinis must be considered as species inquirenda since only poorly described females are known up till now. Wieser (1954) suggested that P. acridentata is a dubious species that could be a synonym to P. neapolitana or P. maculata but we prefer to consider P. acridentata as species inquirendum because there is only a female described and based on this specimen it is not possible to determine its taxonomic position. P. arabica and P. quinquepapilata are also considered as species inquirenda following the suggestion of Micoletzky (1924) and Riemann (1966), respectively. Wieser (1954) also proposed a key based on the presence and absence of ocelli combined with the orientation of the dorsal tooth. P. subterranea and P. tenuicaudata were described by Gerlach (1953 and 1954, respectively) and they are absent in the key proposed by Wieser (1954), probably because these descriptions were published at the same time as the review. P. micoletzkyi Chitwood, 1951 was considered a synonym of P. paramucrodonta by Wieser (1954) but based on the shape of the gubernaculum the former species was distinguished from the latter by Hopper & Meyers (1967) and we agree here with its validity. After Wieser’s review, eighteen species were described by several authors: P. actuaria Vitiello, 1971 ; P. crassispicula Galtsova, 1976 ; P. calvus Lemzina, 1982 ; P. codiuma Pastor de Ward, 1985 ; P. daroae Muthumbi & Vincx, 1998 ; P. filiformis Lemzina, 1982 ; P. graciosa Kulikov, Belogurova & Luzganova, 1990 ; P. gracilis Huang & Wang, 2011 ; P. hexapapilata Blome, 1985 ; P. oculata Kulikov, Belogurova & Luzganova, 1990 ; P. papillata Jensen, 1985 ; P. parazygophora Kulikov, Belogurova & Luzganova, 1990 ; P. salpingifera Blome, 1985 ; P. septempapillata Platt, 1973 ; P. spinosa Gerlach, 1957 ; P. striatus Lemzina, 1982 ; P. triangularis Wieser, 1959 and P. zygophora Blome, 1985 . Among these species, P. spinosa was later transferred to Endeolophos ( Holovachov et al. 2011) and P. cobbiana to Chromadorella ( Blome & Schrage, 1985) . P. attenuata ( Gerlach, 1952) was previously described as Neochromadora attenuata Gerlach, 1952 but transferred to Prochromadorella by Lorenzen (1971). Lorenzen (1971) also considered Trichromadora as a synonym of this genus, but Muthumbi & Vincx (1998a) reinstated the validity of Trichromadora (see below). These authors also redescribed P. ditlevseni .
Diagnosis (modified from Tchesunov 2014): Heterogeneous punctated cuticle along the body, lateral differentiation absent, but dots may be enlarged not forming longitudinal rows. Amphideal fovea oval to slit-like located between four cephalic setae. Pharyngeal bulb single or absent. Buccal cavity with three solid teeth of subequal size. Ocelli may be present. Males usually with cup-shaped precloacal supplements. Marine.
Number of valid species: 33
