Diagnosis. Among all species of Peripus  , P. didontus  is distinctive due to the dense punctation of pronotum ( Fig. 6View FIGURES 5–8; punctation beyond the midlines contiguous to almost contiguous). Additionally, P. didontus  has antennomeres 8–10 clearly longer than wide, paramere pointed apically and longer than median lobe, and median lobe with two subapical teeth.

Description. Forebody length 4.7–5.2 mm. Coloration of head and pronotum dark metallic blue purple; elytra 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 2/5 of segment 7, and 8 orange.

Head with 2–4 rows of punctures on each side of central impunctate area; with sparse micropunctures and microsculpture. Head width/length ratio = 1.30; antennomeres 8–10 longer than wide. Pronotum subquadrate, width/ length ratio = 0.98; with 8–9 rows of punctures in addition to rows of punctures flanking impunctate center; punctures contiguous to almost contiguous; impunctate area in middle as wide as 2–3 punctures; with sparse micropunctures and microsculpture. Pronotum/elytra length ratio = 0.92.

Aedeagus as in Figs. 24–26View FIGURES 24–26; in dorsal view paramere slightly expanding to pointed apex; paramere longer but narrower than median lobe; in lateral view paramere slightly concave; paramere with peg setae as in Fig. 26View FIGURES 24–26. 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 combination of the modern Greek words δύο (two) and δóντι (tooth) and refers to the presence of two teeth on the median lobe of the aedeagus.

Distribution. Known from departments of Caquetá and Vaupés in Colombia, the province of Napo in Ecuador, and the department of Loreto in Peru.

Habitat. Collected in lowland tropical rainforests (elevations 60–600 m) using flight intercept and malaise traps.
