Etymology.
The species name
serraorobonensis
is based on the
type
locality.
Diagnosis.
This species can be distinguished from the other species of
Psychoda
by the following combination of characteristics: eyes separated by 1.5 facet rows; labellum with 3 apical teeth; 14th flagellomere spherical, not drop shaped; ascoids Yshaped, inferior branch 0.5X superior branch; M2 not reaching M1.
Description.
Female. Eye bridge with 4 facet rows (
Fig. 28
); eyes separated by 1.5 facet diameters (
Fig. 28
); antenna with 14 flagellomeres, 1st–10th nodiform (
Figs. 28–30
), 12th–14th reduced, 11th–12th fused (
Fig. 31
), 12th with short neck (
Fig. 31
); ascoids Yshaped (
Fig. 30
); scape cylindrical, 1.5X length of pedicel (
Figs. 28, 30
); pedicel spherical (
Figs. 28, 30
). Palpus formula = 1.0:1.2:1.1:1.3 (
Fig. 29
). Labellum with 3 apical teeth (
Fig. 32
). Wing (
Fig. 33
) with short Sc; radial fork apical to medial fork; radial fork complete and M2 incomplete. Subgenital plate (S8) with anterior margin curved, with moderately apical concavity (
Fig. 34
). Genital digit present.
Male.

Comments.
Psychoda serraorobonensis
Bravo, Cordeiro & Chagas
,
sp. nov.
is morphologically similar to species of the subgenus
Psycha
, principally in the number of flagellomeres and the
type
of fusion of the last flagellomeres (11th–12th fused), but different from
Psycha
by the cylindrical format of the last flagellomere, which in all species of
Psycha
is drop shaped, and by the number of teeth on the labellum, being
3 in
the new species and
4 in
the species of
Psycha
.
Distribution.
Brazil
: Bahia (Serra do Orobó).
