Parachromadorita Blome 1974
Description
Genus Parachromadorita Blome, 1974
The genus Parachromadorita was erected by Blome (1974) to accommodate Dichromadora stygia. Before that, Wieser (1954) transferred this species to Denticulella considering it as closely related to Denticulella pellucida. Denticulella stygia was then transferred to Parachromadorita by Blome (1974) based on the loop-shaped amphid. Parachromadorita is considered close to Chromadora, Chromadorita and Dichromadora, but it is distinguished by the morphology of the buccal cavity, the type of lateral differentiation of the cuticle and the shape of the amphideal fovea.
Diagnosis (modified from Tchesunov 2014): Cuticle homogenous with lateral differentiation of irregular larger dots not arranged into longitudinal rows. Anterior sensilla in three separate circles. Amphideal fovea loop shaped. Buccal cavity with a large dorsal tooth, two smaller ventrosublateral teeth and a field of denticles. Peribuccal pharyngeal tissue swollen dorsally; pharynx ending in a single and pear-shaped bulb. Males with precloacal supplements. Marine.
