Scutum shiny brown to dark brown; scutellum dark brown, microsetose; fore femur brown with apical anterodorsal part with a strong circle shape patch yellowish to light brown; fore tibia brown on dorsal and posterior side with base and apex yellowish and anterior side light brown to yellowish; femur and tibia on mid and hind leg brown; all junction of femur and tibia (“knee”) yellowish; all tarsi yellowish; hind basitarsus shorter than length of tarsi 2–4 combined; haltere uniformly brown; wing 1.42–1.50 mm long; abdomen shiny dark brown with first tergite often slightly paler.
Male postabdomen (Fig. 10). Epandrium in lateral view 1.06 times higher than wide, in posterior view 2.3 times wider than high (before cerci), small setae densely covering posterior portion of epandrium mixed with a low density of large setae; surstylus 1.2 times as high as epandrium, paddle shape with a large circular structure situated basally with lots of short markings within and a distinct dent on the anterior side of the apical portion, setae medium length, covering anterior side and distal half of surstylus; cerci small and slightly blunt apically, 0.6 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 lustrum, a Latin noun, refers to bogs from which most of the species have been collected.
Remarks. The male genitalia are similar to those of Paramyia silvestris. Paramyia lustrum has a lot more marking within the overall surface of circular structure (Fig. 10D). The surstylus is often twisting and not flat in appearance; take care to adjust the position to see the anterior edge properly. Genitalia often tucked within the abdomen, making it harder to see all characters.
Females of Paramyia anguliloba, P.lustrum, P. nitens, P. rectiloba, P. silvestris, P. wheeleri can only be reliably identified through sequencing.
