Psychoda speculata , sp. nov.

( Figs 140–149 )

Etymology. The species name, speculata , is based on the somewhat similar and inverted shapes of subgenital plate and genital chamber.

Diagnosis. Antenna with 14 flagellomeres, the 3 apical globulose and subequal, 11th, 12th and 13th with short neck; subgenital plate with concave lateral margins and a conspicuous transversal line medially, with apical half more sclerotized; 3–5 short setae on internal margin of each lobe; genital digit present; a pair of micropilose oval organs internal to the subgenital plate.

Female. Head ( Fig. 140 ): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1 or 2, hair patch of vertex extending between eyes to facet row 1; eye bridge with 4 facets; eyes separated by 1.5–2.0 facet diameters; 5–7 supra-ocular setae; interocular suture absent; clypeus with 2 or 3 stronger lateral alveoli; frontoclypeal suture absent; antenna with 14 flagellomeres, the 3 apical reduced, globulose and subequal, 11th, 12th and 13th with short neck, spine present on 11th ( Fig. 141 ); scape cylindrical, 1.5 the length of the subspherical pedicel ( Fig. 142 ) ascoids in Y ( Fig. 143 ); palpal formula 1.0:1.0(0.90–1.05):1.0(0.86–1.09):1.2(1.1–1.32) ( Fig. 144 ); labellum with 3 apical teeth and 2 lateral setae ( Fig. 145 ). Wing ( Fig. 146 ): Sc vein ending just beyond base of vein Rs; radial and medial forks complete, veins R5, CuA1, and distal part of veins R1, R2, R3 and R4 slightly darkened. Distitarsus with apical projection ( Fig. 147 ). Terminalia: subgenital plate bilobed, with concave lateral margins and basal band presenting a thin posterior projection medially ( Fig. 148 ); a conspicuous transversal line divides the subgenital plate in a less sclerotized basal half and a more sclerotized apical half; 3–5 short setae on internal margin of each lobe; genital digit present; subgenital plate internally with a pair of micropilose oval organs ( Fig. 149 ); genital chamber subtrapezoidal ( Fig. 148 ).

Male. Unknown.

Distribution. Brazil (Amazonas and Bahia)

Comments. This species is very similar to P. balaenica Quate ( Costa Rica), but subgenital plate is a little longer and with shallower apical concavity in P. balaenica , wich also have eyes separated by just 1.0 facet diameter. The new species is morphologically similar to the species of the subgenus Psychodocha , except for the presence of spine on 11th flagellomere.
