Subgenus Hypherpes

This subgenus is extremely complicated, and contains many undescribed, interdescribed, cryptic, and otherwise problematic species, for which reason the current leading expert in the subgenus is working extensively on a key top the many species within the subgenus.  For this reason, many of our Hypherpes specimens do not have confident identifications as of this time, so we are not willing to add those species onto the website for risk of mass error.  

We have included below CEJG Collection Morphospecies With Information ONLY As We Know It, for which reason, none of the listed CEJGC Morphospecies will have full information until the upcoming Hypherpes key is released.

Below is a list of the species currently recognised to be known from Alaska to South California, followed by the few species we can confidently identify*** to species.
