Cordeiro, Danilo, Bravo, Freddy & De, Claudio J. B., 2011, Taxonomy of Brazilian Psychoda Latreille, 1796 (Diptera, Psychodidae) with the description of thirteen new species, Zootaxa 3101, pp. 1-37 : 24-25

Psychoda ituberanensis , sp. nov.

( Figs 79–88 )

Etymology. The species name, ituberanensis , is based on type locality.

Diagnosis. Antenna with 14 flagellomeres, the 3 apical subequal, separated; 11th and 14th with spines; ascoids in Y; distitarsus without apical projection; subgenital plate slightly wider than long, pilose on distal half, basal band with a thin posterior projection medially; genital digit present.

Female. Head ( Fig. 79 ): vertex, frons and clypeus pilose; hair patch of frons extending to facet row 1; eye bridge with 4 facets; eyes separated by 1.6–2.3 facet diameters; 5–7 supra-ocular setae; interocular suture absent; clypeus with 2 or 3 stronger lateral alveoli; frontoclypeal suture absent; antenna with 14 flagellomeres, the 3 apical reduced, circular, subequal and separated, 14th and 11th flagellomeres with a spine ( Fig. 80 ); scape cylindrical, 1.5 the length of subspherical pedicel ( Fig. 81 ); ascoids in Y ( Fig. 82 ); palpal formula 1.0:1.3(1.2–1.3):1.1(1.1– 1.2):1.5(1.4–1.5) ( Fig. 83 ); labellum with 3 apical and 1 subapical teeth and 2 lateral setae ( Fig. 84 ). Wing ( Fig. 85 ): Sc vein ending just beyond base of vein Rs; radial fork complete and medial fork complete or incomplete; veins R5 and CuA1 darkened. Distitarsus without apical projection ( Fig. 86 ). Terminalia: subgenital plate slightly wider than long, bilobed, pilose on distal half, basal band with a thin posterior projection medially ( Fig. 87 ); genital digit present; internal ornamentation of the subgenital plate complex, with several lines as illustrated ( Fig. 88 ); genital chamber damaged during preparation.

Male. Unknown.

Material examined. Holotype Ƥ BRAZIL, Bahia, Ituberá, Pancagê, Res. Michelin, 09.vi.2007, luminosa, col. E. Alvim & J. Oliveira (MZUEFS). 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 ( INPA); 1 Ƥ Bahia, Ituberá, Pancagê, 10.vi.2007, luminosa, col. E. Alvim & eq. Ecopol (MZUEFS).

Distribution. Brazil (Amazonas and Bahia).

Comments. The shape of antenna apex, wing and subgenital plate of this species is similar to the the descriptions of Psychoda apennata Satchell (Tasmania) , P. aponesos Quate (Caroline Is.) and P. s ub p e n na ta Satchell (Australian region), but these three species have eyes separated by 1.0–1.5 facet diameter, 3rd segment of palpus a little larger than 2nd (except for P. apennata , whose palpal formula is unkown), squamuliferous setae on the sides of subgenital plate (except for P. aponesos , whose pilosity was not described), and genital digit bearing three apical spines (except for P. apennata , whose genital digit is narrow, but projecting beyond posterior margin of plate). P. ituberanensis sp. nov. is different from these three specie by the eye separated by 1.6–2.3 facet diameter, 2nd segment of palpus a little larger than 3rd, subgenital plate without squamuliferous setae and genital digit not reaching posterior margin of subgenital plate, and bearing only 1 spine in the apex.

This species is morphologically similar to the species of the subgenus Psychodocha , except for the presence of spines in the 11th and 14th flagellomeres.
