Sinclair ”; “ CNC/ 1078379 ”; “ HOLOTYPE / Empis (Enoplempis) / manning Sinclair ,/ Brooks & Cumming [red label]” [dissected] ( CNC) . PARATYPES: CANADA. British Columbia: Same data as holotype (1♀, CNC); Manning PP, Lightning Lake , for., 22.vii.2015, 1265 m, N 49°03.52′ W 120°50.48′, B.J. Sinclair (2♀, CNC) .

Diagnosis. This species is distinguished from other species of the subgenus by the grey body and males are very narrowly dichoptic, with unmodified hindleg ( Fig. 320 ), hind tarsomere 1 slightly swollen, hind tibia without long anterior setae, cercus with straight dorsal margin ( Fig. 326 ) and phallus with narrow base and arched apical third ( Fig. 327 ).

Description. Wing length 5–5.5 mm. Male. Similar to E. (En.) susanae sp. nov., except as follows: terminalia ( Figs 326, 327 ): cercus with straight dorsal margin; posterior half tapered, with pointed apex; setae shorter than width of cercus. Subepandrial process extending on either side of phallus. Epandrial lamella elongate, narrow, longer than height; posterior margin distinctly expanded dorsally, rounded, bearing long setae ventrally, length nearly subequal to width of epandrium. Hypandrium narrow, strap-like; without setae. Phallus ( Fig. 327 ) with basal third slightly expanded, tapered apically, sinuous to strong bend at apical third; apical third arched; phallus opening appears restricted to tip [possibly damaged during preparation]; emerging beyond cerci; roughened subapical surface opposite apex of cercus; ejaculatory apodeme two-thirds length of epandrium, Y-shaped, with lateral apodemes positioned near ventral margin with short medial apodeme.

Female. Similar to male, except as follows: frons broader, slightly wider than anterior ocellus; legs stockier, without modified setae and processes; abdomen subshiny.Abdominal pleural membrane without darkened, expanded region; tergite 8 and syntergite 9+10 with pruinescence.

Geographical distribution and seasonal occurrence ( Fig. 329 ). Empis (En.) manning sp. nov. is known only from the type locality in southern British Columbia. Adults were collected in July .

Etymology. The species name manning is a noun in apposition and is named after the provincial park where all the type specimens were collected.

Nuptial gift presentation. Form unknown.
