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.
