Taxonomy of Brazilian Psychoda Latreille, 1796 (Diptera, Psychodidae) with the description of thirteen new species Author Cordeiro, Danilo Author Bravo, Freddy Author De, Claudio J. B. text Zootaxa 2011 3101 1 37 journal article 45976 10.5281/zenodo.205242 abff3177-6762-47ae-bc19-4503f7d41774 1175-5326 205242 Psychoda silvensis , sp. nov. ( Figs 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 ): 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 ); ascoids in Y; palpal formula 1.0:1.0(1.0–1.1):1.1:1.3(1.25–1.3) ( Fig. 134 ); labellum with 3 apical teeth and 2 lateral setae ( Fig. 135 ). Wing ( Fig. 136 ): 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 ). Terminalia: subgenital plate longer than wide, bilobed, pilose except on basal region, with basal band projecting medially as an inverted V ( Fig. 138 ); genital digit present; subgenital plate internally with a transversal line next to the base and concave lines next to the genital digit ( Fig. 139 ); genital chamber wider than long, elliptical ( Fig. 138 ). 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.
