Aprionus thori sp. nov. urn:lsid:zoobank.org:act: 80B22178-C33B-4E10-938D-3DF5E6819571 Fig. 6 Diagnosis A typical representative of the insignis group, Aprionus thori sp. nov. is distinguished by the following male genitalic characters in combination (Fig. 6A): the gonostylus, which is strongly convex posteriorly, has a flat depression subapically above the tooth (↓); the tegmen, with 3–4 large finger pairs, is bluntended (↓); and the gonocoxal projections are prominent (↓). Etymology Thor, the god of thunder, is the son of Odin and his mistress, Jörd. Material examined Holotype SWEDEN: ♂, Småland, Nybro, Bäckebo, Grytsjön Nature Reserve, 56.92° N, 16.10° E, tall coniferous forest with aspen trees, Malaise trap, M. and C. Jaschhof leg., 17 Jul.–21 Aug. 2015 (NHRS, no. CEC283). Paratypes SWEDEN: 1 ♂, same data as for the holotype (NHRS, no. CEC 284); 1 ♂, same data, but 17 Jul.– 11 Aug. 2014 (NHRS, no. CEC 285). Other material studied SWEDEN: 2 ♂♂, Uppland, Uppsala, Fiby NR, 59.88° N, 17.34° E, swampy mixed taiga, near aspen log, MT, MCJ leg., 9 Jun.–23 Jul. 2010 (DEI, nos CEC 286– CEC 287). Differential diagnosis Aprionus insignis, a species similar to Aprionus thori sp. nov., differs as follows: the gonostylus has no depression above the apical tooth; the tooth is smaller and flattened like a fingernail, not solid; the gonocoxal projections are smaller; and the tegmen, with only 2 finger pairs, is rounded apically (see Jaschhof 1998: fig. 161a–c). Other characters Body size 1.3 mm. HEAD. Eye bridge 3 ommatidia long dorsally. A dense row of 8–9 postocular bristles. Neck of fourth flagellomere shorter than node; 3–4 thick, simply hair-shaped translucent sensilla (Fig. 6B). Palpus with 3 segments, first segment slightly swollen, apical segment longest of all. WING. ApicR 1 2–3 times as long as Rs. LEGS. Claws subrectangular, 2 fine teeth. Empodia rudimentary. TERMINALIA (Fig. 6A). Ninth tergite subrectangular, anterior margin fully sclerotized, slightly concave medially. Gonocoxites slightly pointed ...
