Key to the species of Peripus Chatzimanolis and Hightower

1. Pronotum punctation dense, punctures contiguous to almost contiguous ( Fig. 6 ), antennomeres 8–10 clearly longer than wide; aedeagus as Figs. 24–26........................................................................ P . didontus

- Pronotum punctation not as dense ( Figs. 5, 7–8 ), punctures not contiguous; antennomeres 8–10 subquadrate to slightly longer than wide........................................................................................... 2

2. Median lobe with two subapical teeth; paramere pointed apically ( Fig. 29 )............................. P. madrededios

- Median lobe with one subapical tooth; paramere rounded apically ( Figs. 23 , 32 )................................... 3

3 Paramere converging to apex ( Fig. 23 ); paramere shorter than median lobe ( Figs. 21–22 ); pronotum punctation with 1–2 rows of scattered punctures (besides punctures on the midline; Fig. 5 )......................................... P. brunkei

- Paramere slightly expanding to apex ( Fig. 32 ); paramere slightly longer than median lobe ( Figs. 30–31 ); pronotum punctation with 2–3 rows of scattered punctures (besides punctures on the midline; Fig. 8 )......................... P. monodontus
