Bopyridae Rafinesque 1815

Bopyridae Rafinesque, 1815 Parasite of Eucalliacid shrimp (Axiidea, Eucalliacidae). Including Zeaione everta gen. et sp. nov., there are now 20 recent species of bopyrid isopods known to parasitise axiidean shrimp worldwide as ectoparasites (Markham 2001, An et al. 2009, Boyko et al. 2017, Romero-Rodríguez and Álvarez 2025, this work) and one fossil undescribed species (Franţescu 2014) (Table 6) which could belong to either Bopyridae or Ionidae. Bopyrids on axiidean shrimp have been poorly studied when compared to those on upogebiids (see, for example, Markham (2001)) and are in need of more intensive sampling and study. Seven species of Ionidae are known from axiidean hosts; these have been reviewed by Hernáez et al. (2023).
