Psychoda pedunculata View in CoL , sp. nov.

( Figs 106–114 View FIGURES 106 – 114 )

Etymology. The species name, pedunculata , makes reference to the shape of the subgenital plate, where the apical lobes are linked to the base of the subgenital plate by a neck or peduncle.

Diagnosis. Antenna with 14 flagellomeres, the 3 apical reduced, 14th shorter and circular; palpal formula 1.0:0.9:1.0:1.0; subgenital plate with neck to the lobes and internally with a subrectangular structure, wider than long; genital digit present.

Female. Head ( Fig. 106 View FIGURES 106 – 114 ): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1; eye bridge with 4 facets; eyes separated by 0.8–1.1 facet diameters; 5 supra-ocular setae; interocular suture absent; clypeus with 2 stronger lateral alveoli; frontoclypeal suture absent; antenna with 14 flagellomeres, the 3 apical reduced; 14th shorter and circular, with an apical spine; scape cylindrical, 1.5 the length of the subspherical pedicel ( Fig. 107 View FIGURES 106 – 114 ); ascoids in Y ( Fig. 108 View FIGURES 106 – 114 ); palpal formula 1.0:0.9:1.0:1.0 ( Fig. 109 View FIGURES 106 – 114 ); labellum with 4 apical teeth and 2 lateral setae ( Fig. 110 View FIGURES 106 – 114 ). Wing ( Fig. 111 View FIGURES 106 – 114 ): Sc vein ending just beyond base of vein Rs; radial and medial forks complete. Distitarsus with apical projection ( Fig. 112 View FIGURES 106 – 114 ). Terminalia: subgenital plate wider than long, pilose except on the base, with rounded lateral margins and a neck to the lobes ( Fig. 113 View FIGURES 106 – 114 ); genital digit present; subgenital plate internally with a subrectangular structure, wider than long ( Fig. 114 View FIGURES 106 – 114 ); genital chamber elliptical ( Fig. 113 View FIGURES 106 – 114 ).

Male. Unknown.

Material examined. Holotype Ƥ BRAZIL, Amazonas, Silves, Saracá, 30.vi.1997, 6cdc – 1m, no collector name ( INPA). Paratype 1 Ƥ BRAZIL, Paraná, Antonina, Res. Sapitanduva , 02.iii.1987, Malaise trap, Profaupar 4.5 ( DZUP).

Distribution. Brazil (Amazonas and Paraná).

Comments. This species ressembles P. plumosa Tonnoir (Ruwenzori) , but can be differenciated from that by the shape of basal part of subgenital plate and lack of the cylindrical process present on each side on base of subgenital plate of P. plumosa . The specimen presenting a complete antenna has the apical flagellomeres demaged, not allowing conclusions about the fusion of this flagellomeres. Based only on females, and without this character, it is difficult to assign it to a subgenera.
