Some characteristics from the microscope images for the tentative species id: The
postero-lateral projections are found only on segment 9, not segment 8. Based on the key in
Jacobus et al. (2014), it appears to key to
Neoleptophlebia adoptiva or
Neoleptophlebia heteronea, same as
this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the
labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.
