diagnosis
Diagnosis. Adult female highly transformed, lacking external segmentation. Body comprising endosoma embedded in host consisting of well defined head region carried anteriorly on trunk bearing paired lateral lobes, and ectosoma consisting of posterior genito-abdominal lobe bearing paired genital apertures. Adult female exhibiting torsion between endosoma and ectosoma. Head bearing rosette-like array of eight slender lobes. Trunk bearing maxillipeds immediately posterior to junction with head. Maxilliped 2 - segmented, subchelate. Swimming legs lacking. Genitoabdominal lobe bearing median anus carried on small anal prominence. Caudal rami lacking. Egg sacs paired, arrangement of eggs within sac sometimes linear (uniseriate), typically biseriate or multiseriate. Male unknown.
discussion
Remarks. The new genus exhibits a unique combination of features that serve to distinguish it from all other copepod genera. None of the families of copepods that have highly transformed unsegmented bodies and live embedded in polychaete hosts, retains a defined cephalothorax bearing lobate vestiges of paired cephalic limbs or has paired maxillipeds on the anterior embedded part of the trunk and a functional anus on the posterior protruding part of the trunk. This unique morphology makes it difficult to place the new genus in any one of the five families of highly transformed copepods living as mesoparasites embedded in polychaetes.
etymology
Etymology. The name of the new genus is derived from the name of the host genus Jasmineira, combined with – icola, meaning inhabitant.
