Psychoda bahiensis, sp. nov.

(Figs 54–62)

Etymology. The species name, bahiensis, is based on type locality.

Diagnosis. Palpal formula 1:1.3:1.1:1.4; radial and medial forks incomplete; subgenital plate wider than long, subquadrangular, pilose on distal half, with a narrow and acute concavity between lobes; genital chamber subtriangular, with posterior apodeme.

Female. Head (Fig. 54): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1; eye bridge with 4 facets; eyes separated by 1.6 facet diameters; 6 supra-ocular setae; interocular suture absent; clypeus with 2 stronger lateral alveoli; frontoclypeal suture absent; antenna incomplete, flagellomeres distal to 12th lost on preparation, 11th and 12th flagellomeres separated, both with short neck and spines; scape cylindrical, 1.5 the length of the subspherical pedicel (Fig. 55); ascoids in Y (Fig. 56); palpal formula 1:1.3(1.25–1.33):1.1(1.0– 1.25):1.4(1.3–1.39) (Fig. 57); labellum with 3 long apical teeth, 1 short subapical tooth and 2 lateral setae (Fig. 58). Wing (Fig. 59): Sc vein not extending beyond base of vein Rs; radial and medial forks incomplete, base of vein R5 and costal cell slightly darkened. Distitarsus without apical projection (Fig. 60). Terminalia: subgenital plate wider than long, subquadrangular, bilobed, pilose on distal half except the internal margin of the narrow and acute concavity between lobes (Fig. 61); genital digit large, triangular; subgenital plate internally with a semi-circular structure and some lines lateral to the genital digit (Fig. 62); genital chamber subtriangular, with anterior portion rounded, and a posterior apodeme ending in T (Fig. 61).

Male. Unknown.

Material examined. Holotype Ƥ BRAZIL, Bahia, Cachoeira, 20.vii.2004, col. F. Bravo (MZUEFS). Paratype: 1 Ƥ same locality, date and collector of holotype (MZUEFS).

Distribution. Brazil (Bahia).

Comments. This species is similar to P. complexa sp. nov. and P. obeliske Quate (Costa Rica) mainly by the incomplete forks of wing, and large rod-like structure on inner face of subgenital plate, but they can be differenciated by the internal ornamentation, apical concavity of the subgenital plate and by the genital chamber, that presents a conspicuous posterior apodeme in P. bahiensis sp. nov. and P. obeliske, absent in P. complexa sp. nov. As the apical flagellomeres are missing, this species cannot be assigned to any subgenera. Complete specimens, as well as male association, may provide a better discussion about the classification of this species, and the other species with apical flagellomeres unknown.
