Fig. 10 Aprionus paludosus is revived here from synonymy with A. styloideus , which reverses our previous decision on the identity of these two species, while the synonymy of Aprionus bicuspidatus Mamaev, 1998 with A. paludosus is confirmed (see Jaschhof & Jaschhof 2009: 243 ). Our present study revealed A. paludosus to be the most common and most widespread species of the styloideus group. Diagnosis The gonostylus ( Fig. 10A ) is strongly flattened, slightly convex basally, and twice as long as wide, the width being constant from the base to the apex; the basolateral apophysis is of normal size; the large tooth is inserted slightly dorsolaterally rather than right on the apex (↓). The tegmen, which is 2.7 times as long as wide, is broadest below the midlength (↓); the 2–3 pairs of large fingers intersect slightly (↓); the tegminal apex is rounded, seldom more blunt. The anterior corners of the subanal plate have small, dot-like sclerotizations, sometimes surrounded by larger, subrectangular, weakly sclerotized portions (↓). The gonocoxal apodemes are so long that the dorsal bridge, which is narrowly rounded, extends clearly beyond the ventroanterior gonocoxal edge (↓). The postfrons is setose; antennal translucent sensilla are single-pointed; the neck of the fourth flagellomere is shorter than the node ( Fig. 10B ); the palpus is 4-segmented (if 3-segmented, then the apical segment is clearly the result of two fused segments); and postocular bristles number 9–11.

Distribution and phenology Norway , Sweden ( Skåne , Södermanland , Uppland, Dalarna , Västerbotten , Lule Lappmark, Pite Lappmark, Norrbotten ), Finland , Germany ( Schleswig-Holstein , Mecklenburg-Vorpommern ), European Russia ; presumably more widespread, with records in literature (see Jaschhof & Jaschhof 2009 , as A. styloideus ) from Denmark , Latvia , Estonia , and the East Palaearctic in need of validation. Adults were collected from May to August in various types of forest, with some preference of swampy sites.
