Type material: Holotype ♂ ( MUSM): Peru, Pasco, provincia de Oxapampa,Villa Rica, carretera de Bosque Sho’llet
at km 11, 10°41′32″S, 75°18′11″W,alt. 2,150 m, 26.III.2017, leg. R. Constantin. Paratypes: 1♂, 2♀, same locality and date as the holotype. The holotype and a female paratype deposited in MUSM, others paratypes preserved in the author’s collection ( CCo).
Description: Holotype. Length 3.5 mm. Head yellow in front of the base of the antennal sockets, black behind. Pronotum, elytra and abdomen black. Pro-, meso- and metasternum yellow. Antennae black, the ventral face of the first three antennomeres yellow. Maxillary palpi brown, the first joint yellow. Legs yellow, the apex of protibiae, the apical half of mesotibiae, the apical two thirds of metatibiae and the tarsi brown. Head 0.83 times as wide as pronotum, short. Clypeus not protruding. Eyes developed, convex, bulging. Frons concave between the antennal sockets, slightly elevated just behind. Temples straight, short. Cephalic surface bright, thinly punctate on the frons and the vertex, not punctate near the eyes, with a pubescence of thin yellow setae. Antennae as long as the body, the first two antennomeres smooth, the following parallel sided, feebly warty, with brown setae. Pronotum 1.37 times wider than long, feebly convex transversally. Front edge right, rear edge arched and laterally sinuous, lateral edge rounded with the front margin, the bead long and narrow. Pronotal surface shiny, slightly bumped at the base, the punctation thin, sparse, the punctations twice smaller than the interval. Elytra 2.9 times longer than combined width at the base, the punctation rugulose, irregularly disposed and wrinkled, covered with long yellow setae. Aedeagus: tegmen short, with apico-ventral apophysis short and a pair of additional internal foliaceous lamellae; lateral sclerites basally broad and dorsally recurved;median lobe thick and short.
Dimensions of the holotype: TL = 4.0 mm; AL = 4.0 mm; HW = 0.8 mm; IOW = 0.41 mm; OL = 0.32 mm; IAW = 0.1 mm; PL = 0.7 mm; PW = 0.96 mm; EL = 2.95 mm; EW = 1.03 mm. Length of the antennomeres, in mm: aI = 0.3; aII = 0.11; aIII = 0.35; aIV = 0.4; aV = 0.46; aVI = 0.46; aVII = 0.43; aVIII = 0.4; aIX = 0.35; aX = 0.33; aXI = 0.32. Paratypes ♂: length 3.6-4.4 mm.
Paratypes ♀: Differs from the males by the smaller eyes, the narrower head, and shorter antennae. Dimensions of a paratype ♀. TL = 4.0 mm; AL = 2.5 mm; HW = 0.66 mm; IOW = 0.37 mm; OL = 0.26 mm; IAW = 0.14 mm; PL= 0.62mm;PW= 0.97mm;EL= 3.05mm;EW= 1.06mm. Other paratype ♀: length 4.7 mm.
Differential diagnosis: Plectonotum oxapampa sp. nov., is similar to P.inca Wittmer, 1988 . It differs from the latter in the singular colour scheme of the head, and the peculiar appendages of the male tegmen.
Etymology: The specific epithet is related to the provincial name of the type locality. Noun in apposition.
Natural history: Collected beating shrubs along the road to Bosque Sho’llet.
