Psychoda trilobatula, sp. nov.

(Figs 150–158)

Etymology. The species name, trilobatula, is based on the presence of three small lobes on the subgenital plate.

Diagnosis. Antenna with 13 flagellomeres; 13th flagellomere circular, separated from 12th; 12th flagellomere subquadrangular, with short neck and fused to 11th, spines present on 11th and 12th; subgenital plate wider than long, trilobed, pilose on distal half and next to base medially; genital digit present.

Female. Head (Fig. 150): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 2 or 3; eye bridge with 4 facets; eyes separated by 0.9–1.3 facet diameters; 5–7 supra-ocular setae; interocular suture present or not (sometimes just a weak band); clypeus with 2 stronger lateral alveoli; frontoclypeal suture absent; antenna with 13 flagellomeres, the 2 apical reduced; 13th flagellomere circular, separated from 12th, 12th flagellomere subquadrangular, with short neck and fused to 11th, spines present on 11th and 12th flagellomeres (Fig. 151); scape cylindrical, 1.5 the length of subspherical pedicel (Fig. 152); ascoids in Y; palpal formula 1:1.1(1.07–1.21):1.0(0.94–1.11):1.3(1.21–1.40) (Fig. 153); labellum with 3 apical long teeth and 1 subapical short tooth (Fig. 154). Wing (Fig. 155): Sc vein ending in the level of the base of vein Rs; radial and medial forks complete; R5 and CuA1 slightly darkened. Distitarsus with apical projection (Fig. 156). Terminalia: subgenital plate wider than long, trilobed, central lobe with 4 marginal setae, pilose on distal half, hair patch extending anteriorly on median region, almost reaching the base of the subgenital plate (Fig. 157); genital digit present; internal ornamentation of the subgenital plate simple, as illustrated (Fig. 158); genital chamber oval (Fig. 157).
