Useful characters
ID might be aided by any of

1. A flat picture of the wing showing shape of forks of vein M and Cu. For example, Anarete has the fork of M triangular instead of bell shaped.

2. Closer photo of male genitalia. I think this is a male. I don't have the revision of Lestremiinae yet but I hope to acquire it some day (and we have somebody who does).

3. Count of segments in antenna and relative size of pedicel and first flagellomere.
