Type material examined.

Holotype (male): "PERU: Dept. Madre de/ Dios: Pantiacolla Lodge,/ Alto Madre de Dios R./ 12°39.3'S, 71°13.9'W 420 m/ 14-19-XI-2007 D. Brzoska/ ex. flight intercept trap/ PER1B07 004" (SEMC).

Differential diagnosis.

Notionotus peruensis can be distinguished by the particular shape of the aedeagus, being nearly rectangular in the basal half and abruptly narrow in the apical half (Fig. 9F View Figure 9 ).

Description.

Size and form: Body length 1.6 mm. Body form elongate oval, convex in lateral view (Fig. 4K View Figure 4 ). Color and punctation: Dorsally yellow, head mostly yellow and frons pale brown; pronotum with two small black round spots along posterior margin (Fig. 4K View Figure 4 ). Ventrally brown; maxillary palps, mouthparts, antennae (antennal club slightly darker) and legs yellow. Clypeus and labrum with dense, fine, and weakly impressed ground punctation (punctures separated by 2 × their width); pronotum and elytra ground punctation fine, weakly impressed and sparser than on head (punctures separated by 3 × their width). Head: Clypeus and labrum shallowly emarginate anteromedially, lateral margins of the labrum bearing setae. Thorax: Prosternum carinate medially, strongly raised, pointing anteriorly and acute. Elevation of mesoventrite with one transversal ridge, elevated medially, lateral sides concave; longitudinal ridge sharp, the point where the two ridges merged acute (e.g., Fig. 10B View Figure 10 ); elevation flat in lateral view; mesoventrite with triangular shape in ventral view. Metaventrite convex in the median region, pubescent with narrow glabrous patch on the medial and posterolateral area, medial region patch drop-shaped; anterior margin extending to mesoventrite elevation. Metafemora densely covered with hydrofuge pubescence on basal three-quarters. Abdomen: Abdominal ventrites very densely pubescent. Aedeagus (Fig. 9F View Figure 9 ) with basal piece 0.7 × the length of a paramere. Base of the parameres wider than the base of the median lobe; outer margins straight along basal two-thirds, then apically sinuate, inner margins straight along basal two-thirds and then convex and tapering apically; apex of parameres rounded and pointing outwards. Median lobe much shorter than the parameres, basal half rectangular, apical half narrowing abruptly, apex rounded.

Etymology.

The species is named after Peru, the country where it was collected, as well as for being the first species described for the genus in this country.

Distribution.

Known only from the type locality in Peru (Fig. 14 View Figure 14 ).

Life history.

The single specimen was collected at a flight intercept trap; nothing is known about its habitat.
