Type material.

Holotype (male): "Brazil: Amazonas: Manaus/ -2.93079, -59.97514, 75 m/ Ducke Reserve, Igarape Barro/ Branco; Short & team; muddy/ pools in swampy area by stream/ 9.vi.2018; BR18-0609-02B" (INPA). Paratypes (16 exs.): Brazil: Amazonas State: Same data as holotype (13 exs., SEMC); same data except stream margins, 6.vi.2018, BR18-0606-02B (2 exs., SEMC, including DNA voucher SLE2100); Novo Airão Municipio, -2.68396, -60.93840, leg. Benetti, 9.vi.2017, densely vegetated margin of blackwater creek, BR17-0609-04A (1 ex., SEMC, DNA voucher SLE1269).

Differential diagnosis.

See differential diagnosis for Notionotus garciae . In addition, the aedeagus of N. juma has an emargination in the apex of the medium lobe, being a particular feature among the species of the Notionotus lohezi group.

Description.

Size and form: Body length 1.6-1.9 mm. Body form elongate oval, convex in lateral view (Fig. 4E View Figure 4 ). Color and punctation: Dorsally bicolor, head pale brown, pronotum yellow with two small black round spots along posterior margin; elytra dark brown (Fig. 4E View Figure 4 ). Ventrally brown; maxillary palps, mouthparts, and antennae yellow (antennal club slightly darker). Pro and meso legs yellow, meta legs pale brown. Clypeus and labrum with dense, coarse, and moderately impressed ground punctation (punctures separated by 2 × their width); elytra and pronotum ground punctation coarse, moderately impressed and less dense 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, acute and pointing anteriorly. Elevation of mesoventrite with two transversal ridges, elevated medially, lateral sides concave; longitudinal ridge broad anteriorly and sharp posteriorly, the point where the three ridges merged wide and blunt (e.g., Fig. 10C, D View Figure 10 ); elevation flat in ventral 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; anterior margin extending to mesoventrite elevation. Metafemora densely covered with hydrofuge pubescence on basal three-quarters. Abdomen: Abdominal ventrites very densely pubescent. Aedeagus (Fig. 8G View Figure 8 ) with basal piece nearly the same length as a paramere. Base of the parameres as wide as the base of the median lobe; outer margins convex, then curved inwards along apex, inner margins convex along basal two-thirds, and concave at apical third; apex of parameres rounded. Median lobe shorter than the parameres, wide at basal region, slightly narrowing in the midlength, apex wide and emarginate medially; gonopore with an oval shape and situated at apex of the median lobe.

Etymology.

This species is named after the Juma, an indigenous tribe located in the Açuã River, in the southern part of the state of Amazonas-Brazil.

Distribution.

Known only from the Ducke Reserve near Manaus, Brazil (Fig. 15 View Figure 15 ).

Life history.

Specimens were collected in two habitats at the same forest reserve: in detrital pools in an area of shallowly flooded forest with detrital and mud substrate (Fig. 13E View Figure 13 ), and along the margins of a small stream.
