Description. Male. Head. Brown. Maxillary palpus very pale brown. Antenna concolorous with face. Eye bridge 2 facets wide. Face with 5–10 scattered dark longer and shorter setae. Clypeus non-setose. Maxillary palpus with 3 segments; segment 1 longer than segment 2, with 1 (rarely 2) long sharp seta, with a dorsal patch of sensilla; segment 2 with 1 long sharp seta and 4–5 shorter truncate setae; segment 3 shortest, with 4–5 short truncate setae. Antennal flagellomere 4 1.8–2.2x as long as wide, neck as long as broad; longest setae slightly longer than the width of flagellomere. Thorax. Unicolorous brown, Setae dark. Anterior pronotum with 4–5 setae. Prothoracic episternum with 3–5 setae. Scutellum with 2 long setae. Wing. Length 1.3–1.4 mm. Width/length 0.40. R1/R 0.50– 0.60. c/ w 0.60 –0.70. r-m with 1–2 setae. bM non-setose. Haltere pale brown. Legs. Pale yellowish brown. Front tibial organ with dark vestiture, forming a patch (Fig. 3 A). Front tibial spur slightly longer than the tibial width. Abdomen. Brown, paler than thorax. Setae dark and long. Hypopygium, Figs 3 B–D. Brown, paler than abdomen. Gonocoxa longer than gonostylus; ventral setosity sparse, setae at the apical part of medial margin not elongated. Gonostylus elongated, mesial side slightly impressed; setosity sparse, apicomesially with a few elongated setae; bearing a short apical tooth, with 4–6 megasetae (subequal in size, slightly curved); mesially with an elongated seta. Tegmen with roundish apical lobes, without a dorsal finger-like process.
Discussion. Corynoptera inari resembles C. inexspectata and related species (see Hippa et al. 2010) by the gonostylus having a short apical tooth and narrow megaseta on its mesial and lateral sides. It can be distinguished from all of these species by having a rather long seta at the apical third of its gonostylus and by having large lateroapical bulgings on its tegmen.
Etymology. The name is derived from the type locality of the species in Finnish Lapland, Inari.
