Chloropidae, Oscinellinae: Calamoncosis (Rhaphiopyga) glyceriae Nartshuk, 1958. The course scutum (= mesonotum) and the distinct punctures (with microsetulae) on the ocellar triangle are typical features for species belonging into Calamoncosis Enderlein, 1911. For species identification it is important to check if one or two posterior notopleural bristles are present - not to be seen on these images. But the second image (head in profile) lets identify this species: The gena (= jowl) is not evenly rounded but nearly rectangular and slightly protruding with its end just to the level of the anterior edge of the orbit before the eye margin. The lower edge of the upraised head looks a bit bulldozer-like as the elongate proboscis in rest position anteriorly ends just below the vibrissal angle and posteriorly slightly overlaps the hind corner of the jowl. [In swampy biotopes our most abundant C. minima (Strobl, 1893) has a much shorter „normal“ proboscis and a more rounded vibrissal angle, as well a longer and larger ocellar triangle with more punctures on it and with lighter wing membranes]. C. glyceriae with an acute knife-like ovipositor (typical for the subgenus Rhaphiopyga) develops in Glyceria spp., mainly in swamps with stands of G. maxima. In the Italian Alps there occurs an undescribed similar species with 1 + 2 notopleurals and with distinct brown wings not known from other European chloropids.
