Mamaev’s (1998) description of this species, whose only illustration was a schematic drawing of the gonostylus, is insufficient for specific identification. Dicerura formosa, described originally from southern Siberia, is newly reported here from two additional northern European countries. Diagnosis. Characters to differentiate D. formosa from the other species of the formosa group are as follows. The slightly bent gonostylus, whose apex is clearly tapered, bears large setae posteriorly and clearly smaller setae medially, the latter intermingled with short, dense microtrichia (Fig. 16, ↓1). The ventral gonocoxal emargination is slightly convex basally, reinforced by sclerotization, and bordered by two pairs of gonocoxal processes, of which the ventromedial processes are ovate (Fig. 16, ↓2), while the dorsolateral processes are elongate and slightly bent (Fig. 16, ↓3). The semicircular collar of the tegmen has 5 inconspicuous, sclerotized knobs (Fig. 18). The ninth tergite is unusual in two different aspects. First, the posterior edge has a small, broadly V-shaped incision (Fig. 17, ↓4) that is bordered on the inside by subtriangular, densely microtrichose protuberances, and second, the anterior edge is broadly rounded (convex) and reinforced by sclerotization, not straight and faint as in other Dicerura. Two non-genitalic characters uncommon in Dicerura, which were not mentioned in Mamaev’s (1998) description of D. formosa, are the presence of setae on the anepisternum and the long, sometimes even complete M1+2.
