Moved from Subgenus Pachyconops.

Goes to P. excisus in the keys of Camras (1955) and Williston (1882), and all characters which are visible (i.e. most) are in excellent agreement with Williston's detailed description of the synonymous Conops xanthopareus P. excisus here...better than any other post so far, in that the 2nd abdominal tergite is indeed red on the sides, and the two subsequent segments have red bands at there apices.

Postscript 6/30/16: I just noticed an earlier error I made above...and "struck it out". Conops xanthopareus is synonymous with P. brachyrhynchus, not P. exciscus. I don't remember why I brought up xanthopareus, except perhaps that this individual is more colorful than most P. excisus on BugGuide, and in gestalt it does resemble P. brachyrhynchus...perhaps more so than our other excisus posts?!

Much of the description of both species fit well here...but your specimen has the large dark cheek spot of excisus rather than the pale yellow cheeks of brachyryhnchus. Also, a "clincher" character for excisus is the continuous, narrow "pollinose"" band along the entire upper hind-edge of the head. The photo angle here is not good for verifying that, nevertheless I think I can see intimations of that character. If you had a photo from an angle showing the top of the head from behind, then the uninterrupted pollinose stripe character could be unequivocally verified.

Nevertheless, the rest of the fit here with Willston's description of excisus gives me sufficient confidence in that ID here.


This is a male (no theca under 5th sternite...which is a huge, forward-pointing, conical protuberance in this species).

More or less...it was in my backyard.

Fantastic pic. Was it taken in the field?
