Genus Chromadorella Filipjev, 1918
This genus largely resembles Chromadora except for the heterogenous cuticular pattern in the former. This was the main character to propose Chromadorella when C. mytilicola Filipjev, 1918 was described and to accommodate four species previously described as Chromadora ( C. filiformis Bastian, 1865 ; C. sumatrana Steiner, 1915 ; C. sabangensis Steiner, 1915 and C. macrolaimoides ). Among these species only the type species remains currently accepted as valid. C. sumatrana and C. sabangensis were already postulated as possible species inquirenda by Filipjev (1918) and they were later transferred to Prochromadorella and Graphonema , respectively ( Micoletzky 1924; Wieser 1954). C. mytilicola was considered as species inquirendum by Wieser & Hopper (1967), since only female specimens were known, and C. macrolaimoides was returned to Chromadora by Wieser (1954). Later, other two Chromadora species described by Micoletzky (1922) were also transferred to Chromadorella : C. parapoecilostoma Micoletzky, 1922 and C. membranata Micoletzky, 1922 ( Gerlach & Riemann 1973). Wieser & Hopper (1967) described C. trilix and C. vanmeterae and provided a key for the genus including nine ( C. filiformis ; C. circumflexa Wieser, 1954 ; C. parapoecilostoma ; C. membranate ; C. edmondsoni Wieser, 1959 ; C. galeata Wieser, 1959 ; C. parabolica Wieser, 1954 ; C. trilix and C. vanmeterae ) out of the 15 currently valid species. Species missing in this review were described later ( C. duopapillata Platt, 1973 ; C. problematica Boucher, 1976 and C. salicaensis Boucher, 1976 ) or subsequently transferred to this genus from Prochromadorella ( C. cobbiana Johnston, 1938 ). C. macris ( Gerlach, 1956) was described as Trichromadora , and despite the fact that Lorenzen (1971) proposed to synonymise Trichromadora with Prochromadorella , C. macris was regarded as belonging to Chromadorella based on the presence of a continuous lateral differentiation in the cuticle. The species Chromadorella paramucrodonta mentioned in Pastor de Ward (1985) is a mistake. This species is currently known as Prochromadorella paramucrodonta .
Diagnosis (modified from Tchesunov 2014): Heterogeneous punctated cuticle along the body, with lateral longitudinal rows of large dots. Amphideal fovea transverse slit-like. Buccal cavity with three solid teeth of about equal size in most species. Posterior pharyngeal bulb not always distinct, but with plasmatic interruptions that may appear double in some species. Males with five to twelve (mostly five) cup-shaped precloacal supplements. Marine.
Number of valid species: 14
