Aprionus munini sp. nov.
Fig. 8View Fig
The gonostylus is broad and slightly convex basally, then evenly tapered towards the narrow apex (↓, Fig. 8AView Fig), and provided with a moderately large tooth apically. The tegmen, which is 2.8–3.0 times as long as wide, is broadest at or slightly below the midlength; the 2–3 large finger pairs, which are situated far posteriorly, intersect only slightly (↓) or not at all; the tegminal apex is blunt-ended (↓). There may be an exceptional 5 fingers on the one side and 3 fingers on the other side of the tegmen. The sclerotized areas at the anterior corners of the subanal plate are large but often rather weak. The gonocoxal apodemes are so short that the dorsal bridge, which often is slightly rectangular, extends to about the same level like the ventroanterior gonocoxal edge. The postfrons is unsetose; antennal translucent sensilla are almost always single-pointed, exceptionally two-pointed; the neck of the fourth flagellomere is longer than the node ( Fig. 8BView Fig); the palpus is 3-segmented; and postocular bristles number 5–6(–7).
Munin is the other of the two ravens accompanying Odin.
