Overall colour brown to dark brown, frontal triangle brown to dark brown, shiny, reaching lunule; frons 1.14–1.25 times longer than wide and 1.6–1.74 times wider than flagellum; width at widest point 2.3–3.0 times the bottom eye width; gena brown with prunescence, 0.21–0.22 times eye height; postgena dark brown, with light prunescence and 0.25 width of head; scape and pedicel dark brown, first flagellomere trapezoidal, 1.2 times wider than long, dark brown with pale pubescence, arista dark brown and 1.6–1.7 times width of first flagellomere; mild facial carina, visible laterally on the upper part only; palpus dark brown with 4 enlarge setae apically and 1 ventral seta pre-apical, labium dark brown 0.43–0.45 mm and labella dark brown 0.49–0.53 mm long. Scutum shiny dark brown; scutellum dark brown, microsetose; all femur and tibia dark brown; all tarsi brown to light and paler than tibia; hind basitarsus shorter than length of tarsi 2–4 combined; haltere uniformly dark brown; wing 1.42–1.50 mm long; abdomen shiny dark brown. Male postabdomen ( Fig. 16 ). Epandrium in lateral view 1.1 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, paddle shape with a strong elbow shape on the anterior edge and with a large circular structure situated basally with many short markings within, setae medium length, covering anterior side and distal half of surstylus; cerci medium size and pointed apically, 0.74 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 specific name anguliloba is derived from the Latin nouns angulus meaning angle or bend, and lobus meaning lobe or rounded projection, reflecting the strong angle/elbow on the anterior 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.
