Type material. BRAZIL, Bahia, Dantilândia (Fzda. Sossego, 15°06´S 41° 00´W), male holotype, 25.IV.2004, R. Vieira & C. Chagas (MZUEFS); 1 paratype male, same locality, date and collector as holotype (MZUEFS); Bahia, Itabuna (14° 45’ S, 39° 17’ W), 2 paratypes male, 30.V.1999, J.R. Santos (MZUEFS).

Etymology. The species name dantilandensis is based on the type locality.

Diagnosis. This species can be distinguished from other species of Psychoda (Psychodocha) by the following combination of characteristics: eyes separated by 2.5 facet diameters; frons with large patch of alveoli at base and with pair of small patches of alveoli near eyes, triangular shaped; neck 1.0X length of base of flagellomeres; tergite 9 with large pseudospiracular opening; presence of triangular hypandrial plate covering aedeagus.

Description. Male. Frons with 2 small triangular patches of alveoli near eyes ( Fig. 19 ). Eye bridge with 4 facet rows; eyes separated by 2.5 facet diameters ( Fig. 19 ); antenna with 14 flagellomeres, separated, 1st–10th nodiform ( Figs. 21–22 ), 11th and 12th with neck ( Fig. 20 ); flagellomere 14 with small basal neck ( Fig. 20 ); scape cylindrical, 1.5X length of pedicel ( Fig. 21 ); pedicel spherical ( Fig. 21 ); ascoids lost in preparation. Palpus formula = 1.0:1.3:1.3:1.4 ( Fig. 22 ). Labellum with 3 apical teeth ( Fig. 23 ). Wing ( Fig. 24 ) with short Sc; radial fork apical to medial fork; radial and medial fork complete; R2+3 fused to R4; base of M1+2 with somewhat circular swelling. Male terminalia ( Figs. 25–27 ): Gonostylus with pointed apex having same length as gonocoxite. Tergite 9 rectangular, wider than long, with pseudospiracular opening ( Fig. 26 ). Cercus short, club shaped from ventral view, 2.0X length of gonocoxite, with 1 apical tenaculum. Paramere curved apically, ending beyond apex of aedeagus. Aedeagal apodeme 1.5X length of aedeagus, slender; hypandrial plate triangular.
