Westcott, Richard L. & Barr, William F., 2007, Resurrection and review of the genus Knowltonia Fisher, with description of a new subspecies of Chrysobothris Eschscholtz and new species of Acmaeodera Eschscholtz from North America (Coleoptera: Buprestidae), Zootaxa 1481, pp. 49-58 : 52

Knowltonia alleni (Cazier) , new combination

Chrysobothris alleni Cazier, 1938:15 ; Fisher, 1942:243.

Chrysobothris biramosa biramosa: Nelson, 1966:39 (part; misidentification).

This species is known only from Arizona and Colorado ( Fisher, 1942). In color it ranges from green to copper to dark brown, and elytral markings, if present, are postmedian and subdued or in distinct. We have examined one exception, a green female with a broad apical violaceous apical elytral marking. Unlike the other species, nothing has been recorded of its habits, and relatively few specimens have been collected. However, we examined a good series from Arizona, Coconino Co., Moenave, 24-VI-67, taken on Atriplex canescens , ASUC. As Cazier (1938) stated, this species comes closest to K. atrifasciata . It may prove to be only subspecifically distinct.
