Diagnosis. Male genitalic characters to distinguish A. mossbergi from other Aprionus are as follows. The tegmen, which is broadest on the apical half, has 5–6 pairs of large fingerlike processes with slightly intersecting apices; these, together with numerous much smaller processes in their periphery, are dorsomedially oriented ( Fig. 5 View FIGURES 5–10 , ↓ 1). The subanal plate, whose outline resembles a V, has a nearly complete sclerotized border ( Fig. 6 View FIGURES 5–10 , ↓ 2), while the central portions may have several tiny, bright spots, possibly holes. The slender gonostylus with slightly convex base ( Fig. 5 View FIGURES 5–10 , ↓ 3) is dorsoposteriorly oriented; its apex is equipped with a fingernail-like tooth. The safest way to distinguish species of the spiniger group from each other is by means of the subanal plate. In this respect A. mossbergi closely resembles A. karsios Jaschhof , a species occurring in Sweden and Russian Karelia, but the outline of the subanal plate there is a X rather than a V ( Jaschhof & Jaschhof 2009: fig. 101D). Females and preimaginal stages of A. mossbergi are unknown.

Other male characters. Body size 1.2–1.3 mm. Head. Eye bridge 3–4 ommatidia long dorsally. A single row of 8–10 postocular bristles. Neck of fourth flagellomere slightly shorter than node; translucent sensilla usually simply hair-shaped, occasionally thicker (narrow leaf-shaped) and / or two-pointed ( Fig. 7 View FIGURES 5–10 ). Palpus with a variably 3 or 4 segments, with both conditions found in the holotype. Wing. R 1 twice as long as Rs. Legs. Claws sickle-shaped, about 2 fine teeth on basal half. Empodia vestigial. Genitalia ( Fig. 5 View FIGURES 5–10 ). Ninth tergite short; anterior edge sharply contoured but not reinforced; posterior edge broadly rounded to truncated. Gonocoxal apodemes long with broad posterior portions; dorsal transverse bridge tapered towards the rounded apex, occasionally with strongly sclerotized median. Gonostylus with 2 bristles subapicomedially.

Etymology. In naming this species after Bo Mossberg, we honor Sweden’s outstanding, incredibly productive nature illustrator. His oeuvre, recorded in a number of successful books including Nordens flora, has fascinated and inspired generations of nature and art lovers in Sweden and abroad.
