Habitat of Notionotus spp. in the Andean region of Venezuela A Venezuela, Barinas State, seepage habitat of N. liparus (collecting event VZ12-0124-02A) B Venezuela: Aragua, Henri Pittier National Park, seepage habitat of N. liparus , (collecting event AS-06-023) C Venezuela: Zulia, Rio Tukuko, habitat of N. tricarinatus (collecting event VZ09-0129-01A) D Venezuela, Portuguesa, tributary of the Rio Guanare, habitat of N. tricarinatus (collecting event VZ09-0119-03X). Differential diagnosis. Notionotus garciae is very similar to N. juma in the bicolor dorsal coloration, the shape of the elevation of the mesoventrite and the pubescent area of the metafemora. It can be distinguished by the punctation of the pronotum, the elytra shallowly marked (in N. juma is moderately impressed, Fig. 8G ), and the distinctive rounded and broad apex of the median lobe (Fig. 8H ). Description. Size and form : Body length 1.7-1.8 mm. Body form elongate oval, convex in lateral view (Fig. 4G ). Color and punctation : Dorsally bicolor, head mostly brown, frons dark brown, posteromedial margin of the clypeus pale brown and lateral sides and anterior margin yellow; pronotum yellow with two small black round spots along posterior margin; elytra brown, lateral and posterior side of the elytra yellow (Fig. 4G ). Ventrally dark brown; maxillary palps, mouthparts, and antennae yellow. Pro and meso legs yellow, meta legs pale brown. Clypeus and labrum with dense, fine, and weakly impressed ground punctation (punctures separated by 2 x their width); pronotum and elytra ground punctation weakly impressed, fine, and sparser than on head (punctures separated by 3 x 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 ); 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 sparse pubescence along the apical posterior margin. Abdomen : Abdominal ventrites very densely pubescent. Aedeagus (Fig. 8H ) with basal piece 0.4 x the length of a paramere. Base of the parameres narrower than the base of the median lobe; outer margins nearly convex along basal two-thirds, then curved inwards along apex, inner margins nearly straight; apex of parameres acute. Median lobe shorter than the parameres, wide at basal region, narrowing in the midlength and then slightly broadening to apex, apex rounded and wide; gonopore ovate in shape and situated at apical fourth of median lobe. Etymology. This species is named after Andrea Lorena Garcia Hernandez curator at the Coleccion de Insectos de la Universidad del Quindio (CIUQ) in recognition to her passion and contribution of the knowledge of the insects, specially hydrophilids in Colombia. Distribution. This species is known from several collecting events at the Ducke Reserve near Manaus, Brazil (Fig. 15 ). Life history. This species was collected along the margins of small streams in dense forest (Fig. 13D ).
