Diagnosis.
Cybaeus thermydrinos
is grouped with
C. fraxineus
spec. nov.
in the informal
fraxineus
subgroup. Distinguishing the
aspenicolens
and
fraxineus
subgroups is discussed in the
aspenicolens
species group diagnosis. Differentiating the male and female of
C. thermydrinos
from those of
C. fraxineus
spec. nov.
is discussed in the diagnosis of the latter.
