Morphology and Anatomy:

 

 

The taxonomy of pseudaliids is mostly based on differences in the morphology of the male bursa,

More recent analyses with a wider range of species, suggest that the bursal morphology can be quite variable in terms of being lobed or smooth within species (Pool et al., 2020).
