assassin bug - Apiomerus cazieri

assassin bug - Apiomerus cazieri
Boyce Thompson Arboretum, Pinal County, Arizona, USA

Any idea which species this is? I thought it resembled one of the Apiomeris, but am not at all sure.

Head scratchin'
This has actually been bugging me (no pun intended) for awhile. There is no mention of Apiomerus cazieri in Henry and Froeschner's catalog (1988). I also have the revision of the genus by Costa Lima (1951) in front of me and there is no mention of A. cazieri there either. In fact, I cannot find a single literature record for this species. Now that doesn't mean there isn't one, of course, but it does have me curious and albeit it, a bit skeptical.

A lot of these mostly red apiomerines are in the UM museum under A. spissipes as simple color morphs...to which I'm also a bit skeptical. As a result, I'm wading through the revision and other material to try to make some headway with this genus. Unfortunately (for photo ID at least) color does seem quite variable in this genus and most of the differentiation is completely based upon the genitalia.

On a somewhat related note, Henry and Froeschner (1988) specifically mention AZ records for 6 of the 9 Nearctic species: crassipes, flaviventris, longispinis, moestus, spissipes, and subpiceus. I myself caught A. flaviventris outside Bisbee, AZ last September. That leaves immundus (listed with CA and TX records so it might occur there as well), pictipes (listed from CO and NM although I think you mentioned it occuring there too), and repletus (listed from CA) as the only species not occuring in AZ...as we know now.

 
Whoops, my apologies...
You said "that look like this in AZ" not "from AZ." In that case, my last little paragraph can be ignored.

Moved from Apiomerus.

Hard to say.
There are two species that look like this in Arizona. One is A. cazieri, which I collected recently myself. The other is A. pictipes?
