Additional Materials. BRAZIL: Rio de Janeiro, Corcovado Guanabara , [22° 57’ 8.7’’ S, 43° 12’ 42’’ W], VIII. 1966, M. Alvarenga (2 ♀, NMW)GoogleMaps  .

Diagnosis. Among all species of Peripus  , P. brunkei  can be recognized based on the following characteristics: pronotum punctation with 1–2 rows of scattered punctures (besides punctures on the midline); antenna with antennomeres 8–10 subquadrate to slightly elongate, paramere shorter than median lobe; and median lobe with one subapical tooth.

Description. Forebody length 4.2–5.2 mm. Coloration of head and pronotum metallic brown-blue purple; elytra, metallic brown-green with purple overtones; mesoscutellum and ventral forebody brown; mouthparts and antennae light brown to brown; legs yellowish brown except coxae brown; abdomen brown except posterior ½ to 2/5 of segment 7, and 8 orange.

Head with 1–2 rows of punctures on each side of central impunctate area; with micropunctures and dense microsculpture. Head width/length ratio = 1.33; antennomeres 8–10 subquadrate to slightly elongate. Pronotum subquadrate, width/length ratio = 1.02; with 1–2 rows of widely scattered punctures in addition to rows of punctures flanking impunctate center; punctures not contiguous; impunctate area in middle as wide as 3–4 punctures; with micropunctures and dense microsculpture. Pronotum/elytra length ratio = 0.88.

Aedeagus as in Figs. 21–23View FIGURES 21–23; in dorsal view paramere converging to rounded apex; paramere shorter and narrower than median lobe; in lateral view paramere slightly concave; paramere with peg setae as in Fig. 23View FIGURES 21–23. 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 in honor of Dr. Adam Brunke for his contributions to the study of rove beetles.

Distribution. Known from the states of Para, Rio de Janeiro and Santa Catarina in Brazil.

Remarks. We did not designate the two specimens listed here as “additional materials” as paratypes, because they are females (meaning we were unable to confirm their identity with their genitalia) and because they are not as well preserved as the other paratypes.
