Acetropis longirostris Puton, 1875

Morp holo gy. Sexual dimorphism is poorly marked. The colouration of females is similar to that of the previous species, the males are less contrasting in colour. Head is yellow with dark stripe running in the middle. Pronotum has three dark, longitudinal stripes, almost without carina. Scutellum, in males, is often yellow-orange (in females of the same colour as the rest of the body). Femora and tibiae are in body colour, tarsi are darker. Clypeus is short and fairly bluntly terminated, labium is not covered by apex of the clypeus, while in the two previous species the clypeus is elongated, pointed (well visible from the side) and covers the labium. Rostrum reaches at least the 2nd abdominal sternite, but sometimes can also reach the 4th abdominal sternite. Males macropterous, females pseudobrachypterous to various extent. Body length: Štys (1973) gives as follow: male (macropterous form): 6.3–7.1 mm, females (pseudobrachypterous form): 6.4–8.3 mm (up to 9 mm). However, measurements made on the basis of specimens from the authors' collection show that the size range is bigger: males can reach up to 8.0 mm, females with very shortened wings can be only 6.3 mm in length ( Fig. 6 ) while the largest specimens can reach up to 9.1 mm.

Biology. Feeds on Alopecurus pratensis (L.) ( Štys 1973, 1974; Wachmann et al. 2004). Adults are found from late May to early July ( Fig. 7 ), but single specimens can be found much later ( Gierlasiński 2015a).
