I took some microscope photos this morning that might clarify the points I've been trying to make about the tubercles (median frontoclypeal -- middle of face) on the Uenoids that I've been finding, those I think are Neophylax aniqua and Neophylax mitchelli.
Remember Beaty's descriptions --
N. aniqua -- "prominent tubercle on head, often semi-blunt." That's the larva in question at the top of the page: here's a close-up of the tubercle on the head of that larva.
N. mitchelli -- "long pointed tubercle on head, usually directed somewhat posteriorly." Here's another shot of that larva,
and here's a close-up of the tubercle on its head.
They're very distinct. And there's another difference I've noted in the larvae that I've found so far:
the head, pronotum, and mesonotum of what I think is N. aniqua is uniformly dark brown; those of N. mitchelli are much lighter in color.
N. aniqua, 1
N. mitchelli, 1
N. mitchelli, 2
If I need to correct this, I'll let you know. But those tubercle photos might prove to be useful.
