Psychoda atlantica , sp. nov.

( Figs 44–53 )

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.

Distribution. Brazil (Espírito Santo and Paraná).

Comments. This species is morphologically similar to species of the subgenus Psychomora , but present spines in the 11th and 14th flagellomeres and 11th and 12th flagellomeres separated, contrasting with the description of the subgenus.
