Libnotes (Neolibnotes)

Alternative Taxonomy: 

As a subgenus of Limonia:
Limonia (Neolibnotes)


Alexander, C.P. 1972. Insects of Micronesia 12: 816.


The subgenera of Libnotes presented here are as listed by Oosterbroek (2005) and is comprised of genera that had previously been placed under Limonina. The concept of Libnotes presented here is based on the deflection of the branches of the Radial and Medial veins ventrally, thereby causing an enlargement of cell r3.

Libnotes (Neolibnotes) is a small group of 6 species that are grouped based on the characteristic wing venation and modified male hypopygium of its members. The members of Neolibnotes possess an unusually short Rs that is strongly angled from its origin, its short length resulting in Sc ending near the origin of Rs and not at the split of Rs that is typically seen in Libnotes. The male hypopygium of L. (Neolibnotes) is modified from the typical Libnotes type in its elongate gonocoxite and small gonostyli that are equipped with a stout rostral projection and no rostral spines.
