Psychoda pentagona , sp. nov.

( Figs 115–122 )

Etymology. The species name, pentagona , is based on the shape of the genital chamber.

Diagnosis. Eyes separated by 0.5 facet diameters; palpal formula 1.0:0.8:0.8:1.0; subgenital plate subtrapezoidal, pilose except basally, internally with a semi-circular, posteriorly pilose structure; genital digit present.

Female. Head ( Fig. 115 ): vertex, frons and clypeus pilose; hair patch of frons extending as a narrow stripe to facet row 1 or 2; eye bridge with 4 facets; eyes separated by 0.5 facet diameters; 4–5 supra-ocular setae; interocular suture absent; clypeus with 2 or 3 stronger lateral alveoli; frontoclypeal suture absent; antenna incomplete; scape cylindrical, 1.5 the length of subspherical pedicel ( Fig. 116 ); ascoids lost on preparation; palpal formula 1.0:0.8:0.8:1.0 ( Fig. 117 ); labellum with 4 apical teeth and 2 lateral setae ( Fig. 118 ). Wing ( Fig. 119 ): Sc vein ending just beyond base of vein Rs; radial and medial forks complete. Distitarsus with apical projection ( Fig. 120 ). Terminalia: subgenital plate subtrapezoidal, bilobed, homogeneously pilose except basally,with basal band presenting short median posterior projection ( Fig. 121 ); genital digit present; subgenital plate internally with a semi-circular structure pilose on posterior end ( Fig. 122 ); genital chamber subtrapezoidal, with posterior apodeme ( Fig. 121 ).

Male. Unknown.
