Type material.
Holotype (male): "VENEZUELA: Bolívar State/ 6°2'10.5"N, 61°23'57.8"W, 630 m/ Along La Escalera; 31.vii.2008/ leg. A. Short, M. García, L. Joly/ AS-08-058; rocky stream" (MIZA). Paratypes (14 exs.): Venezuela: Bolívar State: same data as holotype (14 exs., SEMC, including DNA voucher SLE1115).
Differential diagnosis.
See differential diagnosis for Notionotus bicolor . In addition, N. insignitus has a particular and unique color pattern in the elytra among the other congeners. The elytra are mostly dark brown, the posterior margins yellow and in the middle region has a characteristic yellow spot.
Description.
Size and form: Body length 1.6-1.8 mm. Body form elongate oval, convex in lateral view (Fig. 4D View Figure 4 ). Color and punctation: Dorsally bicolor, head mostly brown, frons and middle region of the clypeus dark brown, lateral sides of the clypeus pale brown; pronotum yellow with two small black round spots along posterior margin; elytra dark brown, with a yellow spot on the anterior third of the elytra, lateral and posterior margins of the elytra yellow (Fig. 4D View Figure 4 ). Ventrally dark 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, 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, 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 (Fig. 10C 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 basal three-quarters of the anterior margin and along basal one-quarter of the posterior margin, then anterior half of posterior margin with sparse setae. Abdomen: Abdominal ventrites very densely pubescent. Aedeagus (Fig. 8B View Figure 8 ) with basal piece 0.6 × the length of a paramere. Base of the parameres narrower than the base of the median lobe; outer margin straight along basal two-thirds, then apically slightly convex, inner margins convex along basal two-thirds and then apically straight; basal two-thirds of the parameres broad then apical third narrower; apex of parameres rounded and pointing inwards. Median lobe shorter than the parameres, approximately triangular, with acute apex; gonopore triangular and situated at apex of median lobe.
Etymology.
The specific name comes from the Latin word insignitus meaning marked and refers to the distinctive yellow spot in the elytra of this species.
Distribution.
Known only from the type locality in southeastern Venezuela (Fig. 15 View Figure 15 ).
Life history.
The only known series of this species was collected along the margin of a forested rocky stream (Fig. 12B View Figure 12 ).
