Explanation of Names
Pristepyris fraternus Evans, 1963; comb. by Azevedo et al. (2018).(1)
5.8 to 7.5 mm (2)
Similar to P. armifera.

Compared to P. armifera, females of this species have a comparatively longer head that is strongly polished & non-alutaceous, while males have longer setulae on antennal segment 11 and the pronotum depressed along the posterior margin, as well as a distinct aedeagus. (2)

Evans's (2) association of a female to this species was considered tentative.
Florida to Maryland, also Louisiana & Kansas. (2)
Probably Coleoptera larvae, and perhaps Elateridae larvae (as in P. armifera), but host association is unknown. (2)
