Psychoda serraorobonensis Bravo, Cordeiro & Chagas , sp. n. ( Figs. 28–34 )

Type material. BRAZIL, Bahia, Serra do Orobó (12°18´S 40°29´W), female holotype, 29.XII.2004, F. Bravo (MZUEFS).

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. Unknown.

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).
