Diagnosis. Among all species of Peripus  , P. monodontus  can be recognized based on the following characteristics: pronotum punctation with 2–3 rows of scattered punctures (in addition to punctures on the midline); antenna with antennomeres 9–10 subquadrate to slightly elongate, paramere slightly longer than median lobe; and median lobe with one subapical tooth.

Description. Forebody length 5.0– 5.1 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 2/5 of segment 7, and 8 orange.

Head with 1–2 rows of punctures on each side of central impunctate area; with sparse micropunctures and microsculpture. Head width/length ratio = 1.45; antennomeres 8–10 longer than wide. Pronotum subquadrate, width/ length ratio = 0.97; with 2–3 rows of scattered punctures in addition to rows of punctures flanking impunctate center; punctures not contiguous; impunctate area in middle as wide as 4–5 punctures; with sparse micropunctures and microsculpture. Pronotum/elytra length ratio = 0.92.

Aedeagus as in Figs. 30–32View FIGURES 30–32; in dorsal view paramere slightly expanding to rounded apex; paramere slightly longer but narrower than median lobe; in ventral view paramere with slight indentation to accommodate the subapical tooth; in lateral view paramere concave; paramere with peg setae as in Fig. 32View FIGURES 30–32. Median lobe in dorsal view converging to rounded apex; median lobe with a single subapical tooth; in lateral view median lobe becoming narrower near apex.

Etymology. The specific epithet is derived from the combination of the modern Greek words μονó (single) and δóντι (tooth) and refers to the presence of a single tooth on the median lobe of the aedeagus.

Distribution. Known from the communes of Cayenne, Montsinéry-Tonnegrande, Roura, and Saül in French Guiana, and the districts of Marowijne and Sipaliwini in Suriname.

Habitat. Collected in lowland tropical rainforests (elevations 5–280 m) using flight intercept traps.
