Genitalia image sets for selected
dissection voucher specimens of Coxina (Noctuidae:
Erebinae)
Updated July 2015
Genitalia were dissected and images taken by Hugo L. Kons Jr. Images were taken with the GT Vision imaging system {GT} at the American Entomological Institute or the Automontage imaging system {AM} at the University of Wisconsin-Madison Department of Entomology. All structures are the natural three dimensional shape (not slide mounted) except for the juxta/anellus and abdominal cuticle (temporarily slide mounted for imaging).

Note: Coxina hadenoides occurs
in the lower Rio Grande Valley of southern Texas. It closely resembles the more widespread and
sympatric Heteranassa mima in wing
pattern and had been mixed with H. mima in collections, but genitalia and COI 5' both
suggest the two species are not closely related. Heteranassa mima has the two anterior loops of the postmedial line
extending about the same distance distally, whereas in C. hadenoides the posterior of the two
loops extends much farther distally (see red arrows below). The color and contrast of H. mima is
variable and often similar to C. hadenoides where they fly together in south Texas. Coxina cinctipalpis has less light contrast in the medial and
subterminal areas relative to C. hadenoides. The
type of Coxina hadenoides was
examined from a photo provided by Don Lafontaine (July 2015). In the U.S. this name had previously been
applied incorrectly to a dark form of Coxina cinctipalpis with a contrasting white patch basal to
the loop of the postmedial line (bottom left in below photo). The name was also being applied to another
species in Costa Rica.
