Description. ( Fig. 23 View FIGURE 23 ) Total length ♂ 1.4–1.5 mm, ♀ 1.7–1.8 mm. Overall colour brown to dark brown, frontal tri- angle dark brown to black, shiny, reaching lunule; frons 1.1–1.33 times longer than wide and 1.75–1.8 times wider than flagellum; width at widest point 2.13–2.33 times the bottom eye width; gena brown to dark brown with prunescence, 0.14–0.19 times eye height; postgena dark brown, with light prunescence and 0.23–0.30 width of head; scape and pedicel dark brown, first flagellomere subquadrate to slightly trapezoidal, same length than width, dark brown with pale pubescence, arista dark brown and 1.64–1.82 times width of first flagellomere; moderate facial carina, easily visible laterally; palpus brown to dark brown with 5 enlarge setae apically and 1 ventral seta pre-apical, labium dark brown 0.37–0.43 mm and labella brown and apically paler 0.46–0.48 mm long.

Scutum shiny dark brown; scutellum dark brown, microsetose; fore femur brown with apical antero-dorsal part with a slightly paler circle shape, mid and hind femur brown and all tibia brown; all tarsi light brow to yellowish; hind basitarsus shorter than length of tarsi 2–4 combined; haltere brown and slightly darker apically; wing 1.21–1.33 mm long; abdomen shiny dark brown.

Male postabdomen ( Fig. 24 View FIGURE 24 ). Epandrium in lateral view 1.0 times wider than high, in posterior view 2.4 times wider than high (before cerci), small setae densely covering posterior portion of epandrium mixed with a low density of large setae; surstylus 1.3 times as high as epandrium, rounded rectangular shape with a large circular structure, thicker on the posterior side, situated basally with just a few short markings in the middle, setae medium length, covering anterior side and distal half of surstylus; cerci large and pointed apically, 0.89 times length of surstylus in posterior view, with a pair of very long preapical setae and other shorter setae, less than 1/3 its length, apically swollen in lateral view.

Etymology. The species name come from the Latin rectus, meaning straight and lobos (from Greek) meaning lobe, which refers to the fairly straight/parallel side of the surstylus.

Remarks. Females of P. anguliloba , P.lustrum , P. nitens , P. rectiloba , P. silvestris , P. wheeleri can only be reliably identified through sequencing.
