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 ). 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.

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.
