FAMILY PIRUSACCIDAE HØEG & GLENNER, 2019
Diagnosis: As provided by Høeg et al. (2020).
Comment: Monophyly rests on morphology alone because no species has been sampled for molecular analyses. The structure hosting the males (spermatogenic islet) might be homologous with those in Duplorbidae and Chthamalophilidae .
Host: On the galatheoid species Galacantha (syn. Munidopsis) rostrata A. Milne Edwards, 1880.
