Description. Male. Body length 1.9–2.4 mm; wing length 2.1–2.3 mm ( Fig. 7).

Female. Unknown.

Color. Frons and fronto-orbital plate mat black, with low- er half reddish-brown; upper dark orbit touching ovt and ivt; ocellar triangle mat black, grey pollinose; lunule silver brown; face brown; clypeus shining black; gena brown; antenna entirely orange brown; arista brown; palpus yellow, with black setae apically; proboscis yellow; labellum yellow, with yellow setae; scutum brown, grey pollinose presuturaly, with transverse band brown weakly shinning postsuturaly, light yellow laterally and before scutellum ( Fig. 28); scutellum light yellow; postpronotum light yellow, with brown spot centrally; notopleuron light yellow; anepimeron, anepisternum, katepimeron, katepisternum, and meron brownish-black; haltere entirely light yellow; calypters yellow, with margin and fringe brown; wing clear, light yellow at base; legs dark brown, with fore knees yellow; pulvilli yellow; abdomen light yellow, tergites 3–6 with median dark brown spot, tergite 5, tergite 6 with lateral dark brown spot; terminalia entirely dark brown.

Head. Frons not visible above eye margin in lateral profile; 2 reclinate ors and 2 inclinate inwards ori, similar in size; orbital setulae erect in one row; facial keel undifferenciated; eye height/parafacialia+gena: 4; ocellar triangle short, ending before second ors; lunule high, about 28% of frons length; clypeus rounded; epistoma height 0.04 mm; first flagellomere rounded and finely pubescent; arista long, almost same vertical height of eye, finely pubescent; vibrissa long and strong, measuring 2/3 of aristal length.

Thorax. Acr in eight irregular rows; prsc absent; 1+3 dc, presutural and first postsutural shorter than second and third; 2 npl, similar in size. Wings. Wing tip nearer R 4+5 than M; R 4+5 and M straight; C sections 2–4: 0.72:0.16:0.12; ultimate section of CuA 1 with same length of basal section; r-m distal to midpoint of dm. Legs. Fore tibia without pd; mid tibia with 2 pd on middle third.

Terminalia. Epandrium rounded with long setae; cercus short, about 1/3 height of epandrium, with long setae; surstylus rounded, triangular on apex, with about 32 setae; hypandrium short and U-shaped; phallapodeme about 2.5 length of hypandrium; mesophallus well sclerotized, V-shaped; distiphallus sclerotized with two arms, with membrane surrounding it ( Figs 42, 43); ejaculatory apodeme small, at its broader part about 4.0 times wider than constricted area at base ( Fig. 44).

Distribution. Rondônia ( Brazil).

Etymology. The specific epithet refers to the common characters showed by the species within the genus, except the male terminalia.

Remarks. This new species is morphologically similar to P. megapodema sp. nov. in the length of the body and wing and in the general color of the body, but it can be differentiated by the antennae entirely orange brown; surstylus with about 32 setae, distiphallus well sclerotized with two arms and short ejaculatory apodeme.
