Type material.
Holotyp e (male): "BRAZIL: Amazonas, Manaus/ -2.93079, -59.97514, 75 m/ Ducke Reserve/ leg. Short & team; stream margin/ & assoc. backwater swampy area/ 9-10.vi.2018; BR18-0609-03A", "DNA VOUCHER/ Extraction #/ SLE-1553" (INPA). Paratypes (4 exs.): Brazil: Amazonas State: Same data as holotype (2 exs., SEMC); same data except Igarape Barro Branco, muddy pools in swampy area adjacent to stream, BR18-0609-02B (1 ex., SEMC, DNA voucher SLE2102); same data except by unnamed stream, water in palm fronds, BR18-0609-03B (1 ex., SEMC).
Differential diagnosis.
This species has a particular coloration pattern, dark reddish brown, which makes it easily distinguishable among the other species of the Notionotus lohezi group. The shape of the parameres is slightly similar to N. lohezi (Fig. 8F View Figure 8 ) but the apex is less acute and bend much less inward. It can be separated by the triangular shape of the median lobe and acute apex (Fig. 8C View Figure 8 ).
Description.
Size and form: Body length 1.7-1.9 mm. Body form elongate oval, moderately convex in lateral view (Fig. 4C View Figure 4 ). Color and punctation: Dorsally dark reddish brown, lateral margins of clypeus, pronotum and elytra yellow brown (Fig. 4C View Figure 4 ). Ventrally reddish brown, except for black abdominal ventrites; maxillary palps, mouth parts and antennae yellow (antennal club slightly darker). 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 3-4 × 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 with dense hydrofuge pubescence along three-quarters of the anterior basal margin and sparse pubescence along the posterior basal margin. Abdomen: Abdominal ventrites very densely pubescent. Aedeagus (Fig. 8C View Figure 8 ) with basal piece 0.7 × the length of a paramere. Base of the parameres narrower than the base of the median lobe; outer margins slightly convex, inner margins straight; apex of parameres acute and pointing outwards. Median lobe shorter than the parameres, approximately triangular, wide at the basal region, then slightly narrowing to the apex, apex acute, gonopore oval in shape and situated at the apex of the median lobe.
Etymology.
The name is a combination of two Latin words brun meaning dark and badius meaning reddish brown, highlighting the distinguishable dark reddish brown color of this species.
Distribution.
Known only from the type locality near Manaus, Brazil (Fig. 15 View Figure 15 ).
Life history.
The only known specimens were collected along the margin of a stream (Fig. 12C View Figure 12 ).
