Introduction

Species in the family Shiinoidae are parasites of marine fishes and are usually be located on the nasal lamellae or gill filaments of their host fish; species of Parashiinoa can also be found on the fins of their host. Two genera and five species are known currently. See Boxshall & Halsey (2004: 659) for more details as well as a key to the genera.

Diagnosis

Female - Body cylindrical, segmentation somewhat obscure anteriorly but discernable from posterior thoracic through abdominal segments. Abdomen well-devoloped, 4-segmented. Caudal rami well-developed. rostral area produced and bearing first and second antennae; separated from mouth parts by a short necklike constriction. Mouthparts typically poecilostomatous. Maxilliped absent. Legs 1 cyclopoid type. Parasitic on nasal lamellae of marine fish.
Male - Generally as in female, except rostral area not produced. Sexual dimorphism most pronounced in morphology of second antenna but exopod of leg 2 also affected. maxilliped absent. Always embracing female behind rostral area.
