Subfamily Dioncinae Johnston & Tiegs, 1922
Introduction
This small subfamily is represented globally by a single genus, Dioncus Goto, 1899, and 11 species. Postlarvae of Dioncus are reported from skin of sharks but adult specimens occur on the gills of teleosts in the families Carangidae, Echeneidae and Rachycentridae (see Bullard et al, 2000). In Australia, thsi subfamily is represented by 3 species. Species of Dioncus are unusual because adults tend to attach their eggs to the gills of their hosts (Whittington, 1990). Adults are characterised by a septate haptor, 2 testes in tandem and a rounded head with multiple small adhesive openings on each side (Whittington, 2004).
