Genus Xenox
Xenox habrosus
This species has the typical black and hyaline pattern of the genus. There are 3 submarginal cells in the wing, due to an extra complete crossvein. Occasional specimens have one wing with 3 submarginal cells and the other with two. They are lumped here.
Range: COCH, PIMA, STCR
Occurs: Late May to Early October
Xenox xylocopae
Locally, a bit more widespread than X. habrosus, this large species also has black and hyaline patterning. It differs by having only 2 submarginal cells due to the incomplete extra crossvein which is akin to a spur vein.
Range: COCH, GRAH, PIMA, PNAL
Occurs: Mid-June to Mid-November
