Mydas Fly - Nemomydas brachyrhynchus - male

Mydas Fly - Nemomydas brachyrhynchus - Male
Bear Canyon Riparian Restoration Area, west side of Huachuca Mountains, Cochise County, Arizona, USA
May 1, 2014

Moved from Nemomydas.

According to Kondratieff & Welch(1990) and Torsten Dikow's website, the range of N. brachyrhynchus is Arizona into Sonora, Mexico...whereas the range of N. pantherinus is California, Oregon, Washington, and British Columbia (but not AZ).

So this is presumably the male of N. brachyrhynchus...even though it's not in perfect agreement with the description given in Kondratieff & Welch(1990)

How are you ruling out N. ven
How are you ruling out N. venosus? Especially since the proboscis seems to exceed the oral cavity.

Not Opomydas that genus, the the hind leg has length of basitarsus 5 or more times its width. That's clearly not the case here.

Note the antennal club here is longer than the 1st flagellomere, and the proboscis is fairly short. This is indeed Nemomydas.

And it's a male of either N. pantherinus or N. brachyrhynchus.

Moved from Mydas Flies.

Someone suggested Opomydas limbatus
