Comments
Two of the original
five male
cotypes WILLISTON WI designated for
Heteromeringia flavipesflavipes
(as
Heteroneura
) (
WILLISTON, 1896
) have been identified as pale phase males of
Craspedochaeta concinna
(WILLISTON (WI, 1896). Of the remaining
three male
cotypes, one is here designated as the
lectotype
of
H. flavipes
. The single female cotype was not examined.
