Psychoda trilobatula , sp. nov.

( Figs 150–158 View FIGURES 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; 13 th flagellomere circular, separated from 12 th; 12 th flagellomere subquadrangular, with short neck and fused to 11 th, spines present on 11 th and 12 th; subgenital plate wider than long, trilobed, pilose on distal half and next to base medially; genital digit present.

Female. Head ( Fig. 150 View FIGURES 150 – 158 ): 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; 13 th flagellomere circular, separated from 12 th, 12 th flagellomere subquadrangular, with short neck and fused to 11 th, spines present on 11 th and 12 th flagellomeres ( Fig. 151 View FIGURES 150 – 158 ); scape cylindrical, 1.5 the length of subspherical pedicel ( Fig. 152 View FIGURES 150 – 158 ); 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 View FIGURES 150 – 158 ); labellum with 3 apical long teeth and 1 subapical short tooth ( Fig. 154 View FIGURES 150 – 158 ). Wing ( Fig. 155 View FIGURES 150 – 158 ): Sc vein ending in the level of the base of vein Rs; radial and medial forks complete; R 5 and CuA 1 slightly darkened. Distitarsus with apical projection ( Fig. 156 View FIGURES 150 – 158 ). 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 View FIGURES 150 – 158 ); genital digit present; internal ornamentation of the subgenital plate simple, as illustrated ( Fig. 158 View FIGURES 150 – 158 ); genital chamber oval ( Fig. 157 View FIGURES 150 – 158 ).
