Psychoda concavula, sp. nov.

(Figs 71–78)

Etymology. The species name, concavula, makes reference to the comparatively shallow concavity of the subgenital plate.

Diagnosis. Subgenital plate slightly wider than long, pilose except basally, lobes inconspicuous and with basal band projecting posteriorly on median region; genital digit present; internal ornamentation simple, with 2 small curved lines next to the base of genital digit.

Female. Head (Fig. 71): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1 or 2; eye bridge with 4 facets; eyes separated by 1.2–1.6 facet diameters; 7–9 supra-ocular setae; interocular suture generally present; clypeus with 2 stronger lateral alveoli; frontoclypeal suture absent; antenna incomplete; scape cylindrical, 1.5 the length of subspherical pedicel (Fig. 72); ascoids in Y; palpal formula 1:1.2(1.11–1.23):1.0(0.89–1.14):1.2(1.0– 1.41) (Fig. 73); labellum with 3 apical and 1 subapical teeth, and 2 lateral setae (Fig. 74). Wing (Fig. 75): Sc vein ending just beyond base of Rs; radial and medial forks complete; veins R5, CuA1 slightly darkened. Distitarsus with apical projection (Fig. 76). Terminalia: subgenital plate little wider than long, bilobed, pilose except on the base, basal band projecting posteriorly on median region and lobes inconspicuous (Fig. 77); genital digit present; internal ornamentation simple, with 2 curved lines next to the base of genital digit (Fig. 78); genital chamber rounded (Fig. 77).

Male. Unknown.

Distribution. Brazil (Amazonas and Espírito Santo).

Comments. This species ressembles Psychoda novaezealandicae Satchell (New Zealand) mainly by the shape of subgenital plate, but the apical concavity of the last is a little deeper than in P. concavula sp. nov. Also, P. novaezealandicae have long anterior arms and R2+3 reaching R4, different from the new species. As the apical flagellomeres are missing, this species cannot be assigned to any subgenera.
