Moved from Diceroprocta.

Based on characters reviewed here, I am inclined to go with Diceroporcta apache.

Gerry Bunker researched several of the more common and confusing taxa in your area and here is what he had to say regarding traits used for identification:

I have been researching the differences between the three most common species of Diceroprocta to be found in Arizona and I found a paper published by William T. Davis in 1928 that describes all three.

All three species have triangular shaped opercula in males extending about half-way the distance of the underside of the abdomen.

W.T. Davis writes:

Diceroprocta cinctifera
Opercula with the outer edges nearly parallel to each other; 8th segment and middle base of tergum pruinose. Collar and costal margin of fore wing usually bright orange in color.

Diceroprocta apache
Hind margin of pronotum or collar yellowish, or straw colored; eyes reddish and membranes at base of both pair of wings pale; often straw-colored. Pubescence at base of abdomen golden.

Diceroprocta semicincta
Hind margin of pronotum or collar with anerior portion blackish and posterior portion pale. Eighth segmen pruinose, and pubescence at base of abdomen silvery. Eyes darker than in apache (not redish in dried specimens), and membranes at base of all wings darker gray. Usually smaller than apache and with opercula more extended at tips.

D. apache
Has a thin line of black that bisects the anterior portions of the pronotal collar with the posterior portion being orange or straw colored.

D. semicincta
Has an all straw or bone colored pronotal collar with no bisection of black in the anterior portions. D. semicincta maculations (patterns of reds and browns) on the mesonotum are less prominent than in D. apache.

I recommend comparing this image with those under Diceroprocta apache.

The pronotal collar appears clearly divided (dark anteriorly and light posteriorly), a trait characteristic of some populations of the aforementioned taxon. The opercula are sharp and not pointed inward at the tips as seen in D. semicincta.

NOTE: There is still some debate as to how one can accurately make a clear distincton among cinctifera, apache and semicincta.

All three are very similar on several levels and subject to geographic variability (with over lap). Use of the male operculae and shape seems preferred.

The calls of the three taxa are also quite similar and may not be adequately diagnostic for species id. in the field (?).

Still working on this issue ;)
