A New Species of Hatschekiid Copepod (Crustacea: Hatschekiidae) Parasitic on the Porkfish Anisotremus virginicus (Linnaeus, 1758) (Actinopterygii: Haemulidae), with Notes on Previously Known Species of Hatschekia Poche, 1902 Collected from Actinopterygians off Brazil.

This is the first report of a representative of the family Hatschekiidae Kabata, 1979 parasitizing a species of Anisotremus. The number of species of Hatschekia reported in the South Atlantic Ocean was increased to five, including the new species; however, the diversity of hatschekiid copepods in this oceanographic region is still underestimated, most likely being higher than what is currently known.
