Differential diagnosis.
The aedeagus of this species is not exceptionally close to any others. It is superficially similar to N. coya (Fig. 26G View Figure 26 ) but N. atlanticus has the neck of the dorsal plate of the median lobe strongly constricted, and the outer margins of the parameres are nearly straight along their basal 1/2 (Fig. 26L View Figure 26 ).
Description.
Body length 8.9 mm. Coloration: Dorsal surfaces dark brown, with slightly paler (orange-brown) margins of clypeus, pronotum and elytra. Head: Maxillary palps 1.3 × longer than width of head, reddish brown in color, slightly paler (orange) at apex of each palpomere. Thorax: Ground punctation on pronotum and elytra dense and very shallowly impressed. Elytra without rows of serial punctures, each with very faint rows (one dorsal and two or three lateral) of scarce and weakly marked systematic punctures. Prosternum only very weakly medially convex. Posterior elevation of mesoventrite elevated as a triangular pyramid, with posterior face somewhat bisinuate and medial longitudinal ridge extending anteriorly (resembles a nose). Abdomen: Apical emargination of fifth ventrite relatively wide, V-shaped. Aedeagus: (Fig. 26L View Figure 26 ) Overall shape sub-rectangular, 2.0-2.3 × longer than wide; lateral projection on apical region of outer margin of each paramere pointed; at closest point, dorsal inner margins of parameres separated by distance nearly 1/2 greatest width of a paramere; dorsal plate of median lobe with narrow neck along mid section; arms of dorsal plate of median lobe distally converging, 0.3-0.4 × length of dorsal plate of median lobe; each arm parallel sided, apically rounded; notch between arms at base as broad as base of an arm; ventral plate of median lobe triangular, apically acuminate, apex extending between mid-length to second 1/3 of arms of dorsal plate; basal piece 0.3-0.4 × length of a paramere. In lateral view, aedeagus weakly oblique at base, with ventral outline of parameres 3.4 × longer than greatest width near base; dorsal outline of aedeagus in lateral view nearly straight along basal 2/3.
Distribution.
Known from several localities in São Paulo and Rio de Janeiro States, Brazil (Fig. 29A View Figure 29 ).
Habitat.
Specimens have been collected from "...temporary ponds that have leaf litter and aquatic vegetation. These ponds were covered and shaded in the border of the forest, or were in open areas". Localities ranged from sea level to 1150 m in elevation.
Remarks.
The specimen we examined and figured here is from the type locality.
