Psychoda talamanca Quate

( Figs 36–43 )

Psychoda talamanca Quate, 1996: 77 . Type Locality: Costa Rica (Limón, Puerto Viejo de Talamanca ).

Diagnosis. Antenna with 14 flagellomeres, 11th, 12th and 13th fused; palpal formula 1.0:0.8:0.8:1.0; subgenital plate with apical lobes in V and pilose, except basally; internal ornamentation micropilose, genital chamber with posterior apodeme, ending in T next to apex of the subgenital plate.

Female. Head ( Fig. 36 ): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1 or 2; eye bridge with 4 facets; eyes separated by 0.36–0.6 facet diameters; 5 supra-ocular setae; interocular suture absent; clypeus with 2 stronger lateral alveoli; frontoclypeal suture absent, sometimes with a weak band between frons and clypeus; antenna with 14 flagellomeres, 11th, 12th and 13th fused, spines present on 14th and 13th flagellomeres and on the neck of the 11th; scape cylindrical, 1.5 the length of the subspherical pedicel ( Fig. 37 ); ascoids in Y; palpal formula 1.0:0.8(0.8–0.9):0.8(0.7–0.8):1.0(0.8–1.1) ( Fig. 38 ); labellum with 4 apical teeth and 2 lateral setae ( Fig. 39 ). Wing ( Fig. 40 ): Sc vein ending in the level of the base of vein Rs; radial and medial forks complete. Distitarsus with apical and lateral projections ( Fig. 41 ). Terminalia: subgenital plate slightly wider than long, bilobed, pilose except basally, lobes in V ( Fig. 42 ); genital digit present; subgenital plate internally with a line parallel to base and with micropilose on the internal ornamentation ( Fig. 43 ); genital chamber oval, with a posterior apodeme, ending in T next to the apex of the subgenital plate ( Fig. 42 ).

Male. Unknown.

Material examined. Type material: holotype Ƥ COSTA RICA, Limón, Puerto Viejo de Talamanca , Sec. Forest, Sea level, 20.vii.1993, Light trap, col. L. W. Quate ( INBio); paratype Ƥ COSTA RICA, Limón, Puerto Viejo de Tal., mixed forest, 0–100 m, 20–22.vii.1993, Light trap, col. L. W. Quate ( USNM). Others specimens: 8 Ƥ BRA- ZIL, Amazonas, Manacapuru, km 69/3, Cajatuba, 10.x.1998, 3cdc copa, no collector name (5 INPA, 3 MZUEFS).

Distribution. Costa Rica, Brazil (Amazonas).

Comments. Albeit in the original description Quate (1996) present a figure where the genital chamber shows no posterior apodeme, the genital chamber of the holotype present this structure and has the same shape of the Brazilian specimens. This species is morphologically similar to species of the subgenus Psychomora , but present spines in the two apical flagellomeres, contrasting with the description of the subgenus. This is the first record of this species to Brazil.
