Noctuoidea is split into 6 families i.e. Erebidae, Noctuidae,
Notodontidae, Euteliidae, Nolidae and Oenosandridae. The Erebidae
comprises of 18 subfamilies of which 9 are represented in the
neotropical region: Arctiinae, Calpinae, Erebinae, Lymantriinae,
Rivulinae, Anobinae, Hypeninae, Herminiinae and Eulepidotinae.
Most moths in the subfamily Calpinae have proboscises that are
modified to enable them to pierce and feed on fruit. They are
divided into 3 tribes - Phyllodini, Ophiderini and Calpini,
totalling about 400 known species worldwide.
There are 23 species in the genus Epitausa.
All have similarly shaped wings which are adorned with a wavy series
of post-median dots. The stigma at the end of the forewing discal
cell varies in shape and colour according to species. The dark
median line which in perseverans,
rubripincta, pavescens and
atriplaga runs from the apex of the forewing to the inner
margin is not a consistent diagnostic feature of the genus - in
flagrans for example the line begins
two-thirds of the way along the costa.
Epitausa perseverans is found in
Guyana, Brazil and Peru. It almost certainly also occurs elsewhere
e.g. Ecuador and Venezuela.
