Treatment

Psychoda silvensis View in CoL , sp. nov.

( Figs 132–139 View FIGURES 132 – 139 )

Etymology. The species name, silvensis , is based on the type locality.

Diagnosis. Palpal formula 1.0:1.0:1.1:1.3; subgenital plate longer than wide with basal band projecting medially as an inverted V; setae absent on basal region on subgenital plate; genital digit present.

Female. Head ( Fig. 132 View FIGURES 132 – 139 ): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1, almost reaching hair patch of vertex; eye bridge with 4 facets; eyes separated by 1.2–1.3 facet diameters; 7–8 supra-ocular setae; interocular suture absent; clypeus with 3 stronger lateral alveoli; frontoclypeal suture absent; antenna incomplete; scape cylindrical, 1.5 the length of the subspherical pedicel ( Fig. 133 View FIGURES 132 – 139 ); ascoids in Y; palpal formula 1.0:1.0(1.0–1.1):1.1:1.3(1.25–1.3) ( Fig. 134 View FIGURES 132 – 139 ); labellum with 3 apical teeth and 2 lateral setae ( Fig. 135 View FIGURES 132 – 139 ). Wing ( Fig. 136 View FIGURES 132 – 139 ): Sc vein ending just beyond base of vein Rs; radial and medial forks complete; veins R5, CuA1 and costal cell slightly darkened. Distitarsus without apical projection ( Fig. 137 View FIGURES 132 – 139 ). Terminalia: subgenital plate longer than wide, bilobed, pilose except on basal region, with basal band projecting medially as an inverted V ( Fig. 138 View FIGURES 132 – 139 ); genital digit present; subgenital plate internally with a transversal line next to the base and concave lines next to the genital digit ( Fig. 139 View FIGURES 132 – 139 ); genital chamber wider than long, elliptical ( Fig. 138 View FIGURES 132 – 139 ).

Male. Unknown.

Material examined. Holotype Ƥ BRAZIL, Amazonas, Silves, Saracá, 30.vi.1997, 6cdc – 1m, no collector name ( INPA). Paratypes: 1 Ƥ Amazonas, Silves, Saracá, área alterada, 29.v.1997, 7cdc – m, col. TVB/FLS ( INPA); 1 Ƥ Amazonas, Silves, Saracá, 30.vi.1997, 6cdc – 1m, no collector name (MZUEFS).

Distribution. Brazil (Amazonas).

Comments. The general shape of subgenital plate in P. serrana sp. nov., P. silvensis sp. nov. and Psychoda undulata Tonnoir ( Uganda) is similar but this three species can be differenciated by the internal ornamentation of this plate.

As the apical flagellomeres are missing, this species cannot be assigned to any subgenera.
