Fig. 10

Type material. Catocala benjamini ute : holotype ♁ [ PMNH, examined]. Type locality: USA, Utah, Grand Co[unty], Arches National Park, Balanced Rock Area, 1610 m.

Diagnosis. Similar to other subspecies, although slightly larger in size and with an orange-brown ground color, and yellow orange usually infusing other aspects of the maculation; underside with reduced black scaling in both basal and adterminal areas; adterminal not as checkered as in other subspecies.

Distribution and biology. Known only from Grand and San Juan counties in southeastern Utah, in the most northeastern part of the species’ overall range. Adults have been taken in early June. Th e immature stages are unknown. Peacock and Wagner (2009) indicate Quercus × pauciloba Rydb. (= Q. undulata Torr. ; a hybrid from Q. gambelii Nutt. and Q. turbinella ) is the most prevalent and sometimes only oak species at the known collecting localities; they report the absence of C. benjamini ute from nearby stands of Q. gambelii .
