Abstract
Joryma hilsae is a large isopod ectoparasite, protandric hermaphrodites and blood suckers living on the gills. The present study is aimed to identify the J. hilsae on Pellona ditchela using morphological and molecular tools. Morphologically the parasite is having pereonites and pleonites. Confirmation of this parasite was done by 28s rDNA characterization and submitted to GenBank with accession no. KJ637325. The study suggests that morphological characters along with molecular study are essential for validating and identifying the isopods.
