I can empathize with the error...it can be difficult to make a call on Entypus vs. Hemipepsis! It took me a while to get it right on the post below (and I had help from others):

   

Many of us learn from our mistakes (I know I do...sometimes it's the only way I learn! :-).

Upon careful examination of the full-size version of the 2nd image in this series (especially the upper wing) it appears the 1st recurrent vein meets the 2nd submarginal cell significantly beyond the distal 1/4 point of its length from its distal end, and closer to the distal 1/10 or so of the posterior edge of the 2nd submarginal cell. So this does appear to be Hemipepsis.

Then, using Townes(1) key to Hemipepsis, the orange antennae of this female, and the separation of the lateral ocellus from the eye by about 3.5 times its diameter...as well as the Tucson location...all strongly indicate H. toussainti.

As you noted, Entypus unifasciatus californicus is not known from outside CA. Also, in both males and females of that taxon, the hind wing venation has the terminal ends of the nervullus and cubitella nearly opposite one another, whereas in Margarethe's 3rd image here the nervellus ends significantly distal to the cubitella (see Fig. 1A on pg. 7 of Townes(1) for a labelled reference diagram indicating vein terminology here).

Compare both the position of the 1st recurrent vein along the posterior edge of the 2nd submarginal, and the ends of the nervellus and cubitella in Margarethe's 2nd and 3rd images here with those in Robyn's images of E. u. californicus below:

       

according to the UAIC it looks good
