Remarks
"Euclea obliqua is correct name
This species is not in the genus Monoleuca. Superficially the adult stage look alike and share some venation characters (fused R3 + R4), but this is shared with Adoneta species as well. The genitalia of both sexes more closely match Euclea, which is why I placed there when I synonymized Euclea dolliana with this species. The type of obliqua was mislabeled being collected in Florida by Henry Edwards. [see Epstein, M. E. & V. O. Becker. 1994. Combinations and Synonymies in New World Limacodidae, Megalopygidae, Lasiocampidae and Arctiidae (Lepidoptera). Revista brasileira de Zoologia. 10:289-319. (1993); Becker, V. O. & M. E. Epstein. 1995. Limacodidae. in J. B. Heppner (ed.), The Atlas of Neotropical Lepidoptera. Checklist: Part II. 3:128-133.
Monoleuca semifascia and Monoleuca rectifascia are the only two species in this genus. Both share uniquely derived features of the male and female genitalia, which include a dense scale pack that covers the eggs, the only known example in the New World (this has occurred independely in Australia). [see Epstein, M.E. 1996. A new name and generic placement for the misidentified type species of Epiclea Dyar, 1905 (Lepidopetera, Limacodidae). Proc. Entomol. Soc. Wash. 98:812-817." -Marc Epstein (2014) (See original comment here)
