Exoporia is a taxon of the butterflies (Lepidoptera) within the suborder Glossata . It includes the two superfamilies Mnesarchaeoidea and Hepialoidea .

features

The very well established monophyly of the taxon is based on the unique shape of the female genitalia. The mating opening ( ostium bursae ) is separated from the laying opening ( Oviporus ) and lies ventrad (towards the belly) in front of it, as is also the case with the Ditrysia . Unlike these, however, the two are not connected to each other. Sperm that is introduced into the bursa copulatrix by the male must be transported to the spermatheca via the laying opening . That is why the body surface below the laying opening is provided with characteristic furrows. The males also have peculiarities in their sexual organs. Your phallus is membranous and lacks both protractor and retractor muscles . The tenth segment has very well developed supra- and subrectal muscles. The maximally three-parted maxillary palps are small in all species and hidden by the surrounding scales. The wing scales have strong secondary grooves in many species. The abdomen has a great number of ganglia, five or six . Autapomorphies, which have also developed in parallel in the Lophocoronoidea , are condyles dorsally on the head at the bases of the antennae, which are sometimes very strongly developed and the wing artery Rs4, which is clearly postapical .

The structure of the eggshells and embryogenesis are also characteristic . The eggs quickly turn black after being laid. The epicranial indentation on the head of the caterpillar is unusually small. The caterpillars probably have a number of autapomorphies in their hair.

In females of the rootworm (Hepalidae) and the Mnesarchaeidae it has been shown that they release pheromones via the hind wings. However, further details have not yet been researched.
