* Both of the females depicted above from Yasuni
National Park (Napo), Ecuador,
and Rondonia, Brazil, seem best matched to Lemaire description
of Dirphia fraterna. However, Lemaire mentions that the am line
is only slightly sinuate and his images show a much straighter am line
than is present on both these specimens. This may be normal variation,
or perhaps an undescribed subspecies or two is depicted. Charles Bordelon
mentions the Yasuni N.P. specimen is much darker than the specimen from
Brazil.
Lemaire mentions that Dirphia thliptophana is quite similar
to D. fraterna and Dirphia thliptophana is darker and
has a more sinuate (in his image) am line,
closer to the specimens depicted, than does D. fraterna.
However, he also reports Dirphia thliptophana has
a convex pm line, much more so than in the darker specimen
from Yasuni.
