Diagnosis. Peripus madrededios  is one of the two species of Peripus  (along with P. didontus  ) with two subapical teeth on the median lobe. Unlike P. didontus  , the punctation of the pronotum is not contiguous and there are (at least) three rows of punctures in addition to the punctures along the midline. Additionally, antennomeres 8–10 are subquadrate to slightly elongate in P. madrededios  (clearly longer than wide in P. didontus  ).

Description. Forebody length 5.2–5.5 mm. Coloration of head and pronotum dark metallic blue purple; elytra brighter, metallic blue-green; mesoscutellum and ventral forebody shiny brown; mouthparts and antennae light brown to brown; legs brown except joints and tarsi yellowish brown; abdomen brown except posterior ½ to 2/5 of segment 7, and 8 orange.

Head with 2–3 rows of punctures on each side of central impunctate area; with dense micropunctures and microsculpture. Head width/length ratio = 1.28; antennomere 8 longer than wide; antennomeres 9–10 subquadrate to slightly elongate. Pronotum subquadrate, width/length ratio = 0.97; with 3–5 rows of scattered punctures in addition to rows of punctures flanking impunctate center; punctures not contiguous; impunctate area in middle as wide as 3–4 punctures, but impunctate area wider posteriorly; with dense micropunctures and microsculpture. Pronotum/ elytra length ratio = 0.99.

Aedeagus as in Figs. 27–29View FIGURES 27–29; in dorsal view paramere converging to pointed apex; paramere longer but narrower than median lobe; in lateral view paramere concave; paramere with peg setae as in Fig. 29View FIGURES 27–29. Median lobe in dorsal view converging to rounded apex; median lobe with two subapical teeth; in lateral view median lobe becoming narrower near apex.

Etymology. The specific epithet is derived from the name of the department of Peru (Madre de Dios) where these specimens were collected.

Distribution. Known from the department of Madre de Dios in Peru.

Habitat. Collected in lowland tropical rainforests (elevations 290–420 m) using flight intercept traps.
