Redescription and neotype designation for the poorly known fish parasitic cymothoid Joryma brachysoma (Pillai, 1964) (Crustacea: Isopoda) from India

A neotype is designated for Joryma brachysoma (Pillai, 1964). The general morphology and appendages of the female and male stages are illustrated and re-described based on the neotype and several additional fresh specimens collected from the type host Pellona brachysoma Bleeker (=Sardinella brachysoma Bleeker) from nearby the type locality. The present redescription and neotype designation further resolves the taxonomic ambiguity regarding the species identification and conserves the name of J. brachysoma.
