Description. Male. Body length 2.1 mm; wing length 2.0 mm (Fig. 20).  
Female. Body length 2.7 mm; wing length 2.2 mm (Fig. 21).  
Color. Frons mat black; fronto-orbital plate shining black; upper dark orbit touching ov and ivt; ocellar triangle mat black; lunule grey; face black with grey pollinose; clypeus black subshinig; gena dark brown; antenna and arista entirely brown; palpus brown; proboscis light brown; labellum light brown, with brown setae; scutum dark brown, weakly shining; scutellum dark brown; postpronotum, notopleuron, anepimeron, anepisternum, katepimeron, katepisternum and meron dark brown; haltere entirely yellow; calypters light yellow with margin and fringe black; wing clear, yellow at base; legs dark brown; pulvilli yellow; abdomen entirely shining dark brown.  
Head. Frons slightly visible above eye margin in lateral profile; 2 reclinate ors and 2 reclinate inwards ori, similar in size; orbital setulae erect in one row; facial keel undiferenciated; eye height/parafacialia+gena: 0.5; ocellar triangle short, ending before second ors; lunule high, 20% of frons length; clypeus rounded; epistoma height 0.04 mm; first flagellomere rounded and finely pubescent; arista long, more than 2/3 of vertical height of eye, finely pubescent; palpus flattened; vibrissa short and strong, measuring about 1/3 of aristal length.  
 Thorax. Acr in eight irregular rows; prsc present; 1+3 dc, presutural and first postsutural with same size, smaller than second and third, this longer than anterior one; 2 npl, anterior one shorter than posterior one. Wings. Wing tip nearer to R 4+5 than to M; R 4+5 and M erect; C sections 2–4: 0.60:0.20:0.20; ultimate section of vein CuA 1 1.1 the length of basal section; r-m distal to midpoint of dm. Legs. Fore tibia without pd; mid tibia with 3 pd on the middle third.   
Terminalia. Epandrium large and rounded with long setae; cercus long, about 2/3 height of epandrium and with long setae; postgonite with two basal setae in lateral view; surstylus oblong with about 13–20 setae; hypandrium U-shaped; phallapodeme about 2.5 times the length of the hypandrium; mesophallus sclerotized; distiphallus tulip-shaped (Figs 76, 77); ejaculatory apodeme broad, more pointed on upper part, at its broader part about 4.8 times wider than the constricted area at base (Fig. 78). Oviscape (Fig. 79). Spermathecae (Fig. 80).  
Distribution. Mato Grosso do Sul (Brazil).  
 Etymology. The specific epithet is derived from the Latin words planus (flat) and palpis (palpus), referring to the flattened palpus of the species.   
 Remarks. This new species is morphologically similar to P. kallima in the dark coloration of the body, but it can be distinguished by the hyaline wing, palpus flattened, postgonite with two setae, surstylus with about 13–20 setae, and a distinct tulip-shaped distiphallus.
