Psychoda matogrossensis , sp. nov.

( Figs 89–96 )

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

Diagnosis. Eyes separated by 2.3–2.7 facet diameters; hair patch of frons extending to facet row 3; subgenital plate wider than long; subgenital plate homogeneously pilose, with a complex sclerotized structure internally; genital digit absent; genital chamber subrectangular, longer than wide.

Female. Head ( Fig. 89 ): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 3; eye bridge with 4 facets; eyes separated by 2.3–2.7 facet diameters; 5–6 supra-ocular setae; interocular suture weakly sclerotized; clypeus with 2 stronger lateral alveoli, sometimes not evident; frontoclypeal suture present; antenna incomplete; scape cylindrical, 1.5 the length of subspherical pedicel ( Fig. 90 ); ascoids in Y; palpal formula 1.0:1.2(1.18–1.22):1.2(1.18–1.26):1.5(1.35–1.59) ( Fig. 91 ); labellum with 3 apical and 1 subapical teeth and 2 lateral setae ( Fig. 92 ). Wing ( Fig. 93 ): Sc vein not extended beyond base of vein Rs; radial and medial forks complete; veins R5, CuA1, and distal part of veins R1, R2, R3 and R4 slightly darkened, and base of R5 with a brown spot. Distitarsus without apical projection ( Fig. 94 ). Terminalia: subgenital plate wider than long, bilobed, with convex lateral margins, homogeneously pilose ( Fig. 95 ); genital digit absent; internal ornamentation of subgenital plate complex, as illustrated ( Fig. 96 ); genital chamber subrectangular, longer than wide ( Fig. 95 ).

Male. Unknown.

Material examined. Holotype Ƥ BRAZIL, Mato Grosso, Barão de Melgaço, baia de Bracoruré, 07.iv.1998, 20 cdc – m, col. RF /FLS/RDN ( INPA). Paratypes: 3 Ƥ same locality, date and collectors of the holotype (2 INPA, 1 MZUEFS); 4 Ƥ BRAZIL, Pará, Santarém, Chac, N. S. Nazaré, km 13, mata, 27.xi.1998, 8 cdc, no collector name (2 INPA, 2 MZUEFS).
