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.
FIGURES 140–149.

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
).

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.
