Etymology. The species name, atlantica, is based on the known distribution of the species, in the Atlantic forest.

Diagnosis. Antenna with 14 flagellomeres, 12th and 13th fused together, 14th separated and shorter; palpal formula 1.0:1.1:1.0:1.1; subgenital plate with a heart shaped center and base projecting posteriorly on each side, heart shaped part also projecting internally to the base of subgenital plate.

Female. Head (Fig. 44): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1; eye bridge with 4 facets; eyes separated by 1.1–1.6 facet diameters; 6 supra-ocular setae; interocular suture absent; clypeus with 1 stronger lateral alveolus; frontoclypeal suture absent; antenna with 14 flagellomeres, the 3 apical reduced (Fig. 46); 14th flagellomere circular, shorter, separated, 13th and 12th flagellomeres fused together; 11th and 14th flagellomeres with spine; scape cylindrical, 1.5 the length of subspherical pedicel (Fig. 45); ascoids in Y (Fig. 47); palpal formula 1.0:1.1(1.05–1.16):1.0(0.89–1.0):1.1(1.0–1.21) (Fig. 48); labellum with 4 apical teeth and 2 subapical setae (Fig. 49). Wing (Fig. 50): Sc vein ending in the level of the base of vein Rs; radial and medial forks complete. Distitarsus with apical projection (Fig. 51). Terminalia: subgenital plate bilobed, with a heart shaped center and base projecting posteriorly on each side, pilose, except basally, with a few long setae on apices of basal lateral projections (Fig. 52); heart shaped part with pilose lateral expansions and projecting internally to the base of subgenital plate; genital digit present; subgenital plate internally with a small elliptical mark medially, basal to the genital digit, and a conspicuous line on each basal lateral projection, as illustrated (Fig. 53); genital chamber oval (Fig. 52).

Male. Unknown.
