GoogleMaps Holotype and two female paratypes deposited in the collection of the MUSM, two paratypes preserved in author’s collection ( CCo) .
Description: Holotype. Length 3.8 mm. Head yellow anteriorly, black behind the antennal sockets. Antennae black, the ventral face of the first two antennomeres yellow, the third brownish yellow. Elytra brown. Legs yellow, the apical half of metatibiae and the tarsi brown. Abdomen brown, the last visible sternite yellow. Head 0.9 times as wide as pronotum, the clypeus protruding. Eyes developed, bulging, the interocular space as wide as the half of head. Frons flattened between the eyes. Temples short, strongly narrowing backwards. Cephalic surface bright, thinly punctate, with thin yellowish setae. Antennae as long as the body, the first two antennomeres smooth, the following parallel sided, slightly warty, covered with thin brown setae.Pronotum 1.4 times wider than long, transversally convex. Front edge arched, rear edge angular, lateral edge rounded with a narrow bead and a small emargination in front of the basal corners. Pronotal surface shiny, thinly punctate, with punctations 1.5 times smaller than intervals. Elytra 2.7 times longer than combined width at the base, markedly and irregularly punctate, covered with long, thin, recumbent yellow setae. Aedeagus: tegmen with lateral lobes strongly reduced and notched posteriorly, dorsally extended; the pair of apico-ventral apophyses dorsally recurved as also the long lateral sclerites; median lobe broad and short.
Dimensions of the holotype: TL = 3.8 mm; AL = 3.8 mm; HW = 0.84 mm; IOW = 0.39 mm; OL = 0.34 mm; IAW = 0.14 mm; PL = 0.66 mm; PW = 0.93 mm;
EL = 2.75 mm; EW = 1.02 mm. Length of the antennomeres, in mm: aI = 0.25; aII = 0.11; aIII = 0.22; aIV = 0.24; aV = 0.24; aVI = 0.22; aVII = 0.22; aVIII = 0.22; aIX = 0.22; aX = 0.21; aXI = 0.22. Paratype ♂: length 3.7 mm.
Paratypes ♀: Differ from males in the smaller eyes, the shorter antennae, and the extension of the black patch of the pronotum, covering the apical half. Dimensions of one paratype ♀.TL = 3.7 mm; AL = 2.5 mm; HW = 0.7 mm; IOW = 0.42 mm; OL = 0.18 mm; IAW = 0.18 mm; PL = 0.68 mm;PW = 0.96 mm; EL = 2.8 mm; EW = 0.98 mm. Other paratype ♀: length 4.1 mm.
Differential diagnosis: Plectonotum bicoloricolle sp. nov., is similar to the Ecuadorian species P. macar-
aense Constantin, 2010, by the habitus, colour pattern and pronotal shape. It differs from the latter in the different aedeagus shape.
Etymology: Specific epithet recalls the peculiar pronotal colour.
Natural history: Collected beating shrubs and trees on the edge of a small wood.
