Remarks.
The type locality of
C. melanderi
is
Santa Ana
,
California
, just southeast of Los Angeles. Only two males of this species have been collected, both in the same sample. The type series of
C. melanderi
had only two specimens, the male
holotype
and a female
paratype
. We have no photos of these specimens, but
Cook’s (1975)
original illustrations are good enough for the recognition of the species. There are no records for species of
Cooka
in the BOLDSystems website.
