Key to species of Pristerophora

Modified from Smith & Mondaca (2015). Males have metatibial spurs absent and elongate antennal clubs approximately equal in length to remaining basal antennomeres. Females have two metatibial spurs and short antennal clubs that are significantly shorter than remaining basal antennomeres.

1. Protibial spur present. Total length usually greater than 7 mm. Elytra color and setae consistent throughout, not generally mottled or patchy..................................................................................... 2

- Protibial spur absent. Total length less than 7 mm. Elytra color and setae inconsistent throughout, often giving a mottled or patchy appearance......................................................... Pristerophora picipennis (Philippi)

2. Clypeal apex medially rounded or broadly truncate, not reflexed. Labrum distinctly protruding beyond clypeal apex in dorsal view ( Fig. 9 ). Pronotum with dense, erect setae................................. Pristerophora rothmanni new species

- Clypeus medially emarginate, reflexed. Labrum not visible (or weakly visible) beyond clypeal apex in dorsal view. Pronotum with mix of dense, thick, white, recumbent setae and scattered, yellowish-brown, erect setae.......................... 3

3. Total length greater than 9.5 mm. Male with bulbous eyes separated by 1–2 eye-widths ( Fig. 6 )................................................................................................. Pristerophora longipes (Philippi)

- Total length less than 9.5 mm. Male with eyes not enlarged, separated by 4 eye-widths ( Fig. 7 ).................................................................................................... Pristerophora paulseni Smith
