A New Species of Free-Living Nematodes (Desmodorida, Desmodoridae) in the Romanian Black Sea Waters

The paper reports the record of Pseudochromadora gomoi sp.n. in circalittoral habitats (at depths 47–59 m) Romanian Black Sea waters. species is characterized by a unispiral amphidial fovea, presence lateral alae stretching from posterior end cardia to level cloacal opening, but also shows unique features found other Desmodorida genera (i.e., precloacal ventral ala males similar several Desmodora or Echinodesmodora and eight subcephalic setae on head capsule). constrictor cuticle ring orange elongated ducts anterior body part as Pseudodesmodora lacrima, Leduc Wharton, 2010, were noted. morphometric measurements our differ most reported specialty literature. We extracted counted all desmodorid individuals 9 meiobenthic samples collected June 2020, performed detailed morphological analysis 12 (5 females 7 males) belonging species, highlighting dissimilarities with related species.
