Figs 5 View FIGURE 5 A, B

Description. Male. Head. Brown. Maxillary palpus very pale brown. Antenna concolorous with face. Eye bridge 2–3 facets wide. Face with 4–5 scattered dark longer and shorter setae. Clypeus non-setose or with 1 dark seta. Maxillary palpus with 3 segments; in some specimens segment 2 and 3 fused; segment 1 longer than segment 2, segment 1 with 1–2 long sharp setae, with a dorsal patch of sensilla; segment 2 with 1 long sharp seta and 3–4 shorter truncate setae; segment 3 shortest, with 4–5 short truncate setae. Antennal flagellomere 4 1.8– 2 x as long as wide, neck shorter than broad; longest setae longer than the width of flagellomere. Thorax. Unicolorous dark brown. Setae dark. Anterior pronotum with 2–3 setae. Prothoracic episternum with 2–5 setae. Scutellum with 2 long setae. Wing. Length 1.3 mm. Width/length 0.40–0.45. Anal lobe rather distinct. R 1 /R 0.50–0.60. c/ w 0.70 – 0.75. r-m non-setose. bM non-setose or with 1 seta. Haltere pale brown. Legs. Pale yellowish brown. Front tibial organ with pale and sparse vestiture forming a patch. Front tibial spur slightly longer than tibial width. Abdomen.

Brown, slightly paler than thorax. Setae dark. Hypopygium, Figs 5 View FIGURE 5 A, B. Brown, as abdomen. Gonocoxa longer than gonostylus; ventral setosity of gonocoxa sparse, setae at the apical part of the mesial margin not elongated. Gonostylus elongated, mesial side slightly impressed; setosity sparse, apicomesially with a few elongated setae; with a long and strong apical tooth; with 6–7 subapical megasetae (subequal in size, slender, straight or slightly curved, sharp) on a shallow mesial lobe,. Tegmen with small, sharp, apicolateral lobes, without a dorsal finger-like process.

Discussion. Corynoptera salmelai   resembles C. spiciforceps   in having a rather apically narrow gonostylus with a strong apical tooth and 7–8 narrow, perpendicularly placed megasetae at the apical third of the gonostylus. Unlike in Corynoptera spiciforceps   , the gonostylus of C. salmelai   is slightly bulged mesially at the megasetae, it lacks the elongated seta at the middle of its gonostylus, present in C. spiciforceps   , and it has its tegmen with sharp apicolateral corners, whereas C. spiciforceps   has its tegmen apically rounded ( Figs 5 View FIGURE 5 and 6 View FIGURE 6 ). Furthermore, C. spiciforceps   has a distinct sensillar pit on its maxillary palpus, whereas the sensilla are in a patch in C. salmelai   .

Etymology. The species is named after the Finnish entomologist, Dr. Jukka Salmela, Rovaniemi, for his outstanding collection activity.
