Any ideas which Pnirontis this might be? I've pretty much ruled out modesta.

Question
How did you rule out P. modesta? I ask not because I doubt the conclusion but because those characters may be useful for a more specific determination. In all likelihood, this is P. infirma since P. modesta was the other main contender.

Happy New Year
I ruled out P. modesta because this specimen does not have spines on both sides of the front tibia. I'll do some more research on P. infirma keys. Thanks for the advice

And to you too
Perfect, just the kind of answer I was looking for! 2 of the 5 Pnirontis have a single protibial series of spines while the other three species have two series such as in modesta. Of the two uniseriate Pnirontis, languida has immaculate connexiva. As this specimen has very obvious markings, it is Pnirontis infirma.

Confirmation
I found an excellent paper from University of Florida Entomology Department.
Literature-based Key to Reduviidae of Florida states P. languida having "connexivals without dark spots" and P. infirma with "a small black spot."

Daniel, thank you for confirming.
