Buenas, mi primer posteo por acá, me gustaría saber si se pueden identificar estos ejemplares, al parecer de la misma especie, hallados en el Parque Nacional Talampaya, La Rioja, Argentina el 26/02/2017. El ambiente es Monte de Llanuras y se encuentra aproximadamente a los 1.200 m s.n.m.

Gracias de antemano y saludos!
Jorge La Grotteria

Maybe something like a Proctacanthus sp. ?

This is a female Lochmorhynchus sp. -- very much like a Proctacanthus...

Cheers,

Eric

Hello Eric. How do you separate these genera?

Hi Reinoud,

Both genera are in the 'Apocleine' group of Asilinae (w/o anatergal setae); distinctive, as both w/ r4 & r5 veins ending in costa above tip of wing. Lochmorhynchus ovipositor w/ apical pair of flap-like appendages, no spines; restricted to so. S. Amer. (Argentina & Chile). Proctacanthus (+ Taurhynchus, Eccritosia & Proctacanthella) have apical cluster of spines on ovipositor, are widespread in Americas.

Cheers, Eric
