Aprionus paludosus Jaschhof & Mamaev, 1997 stat. rev. 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. Material examined Specimens (incl. types) in DEI listed by Jaschhof (1998), specimens in NHRS listed by Jaschhof & Jaschhof (2009). SWEDEN: 1 ♂, Skåne, Klippans, Skäralid, Liema, beech forest, MT, SMTP (trap 37, collecting event 831), 20 May–11 Jun. 2004 (no. CEC 328); 1 ♂, Uppland, Uppsala, Fiby NR, 59.72° N, 17.34° E, mixed swampy taiga, MT, MCJ leg., 23 Jun.–28 Jul. 2009 (no. CEC 329); 1 ♂, Uppland, Älvkarleby, Båtfors, 60.27° N, 17.19° E, blueberry-pine forest, MT, SMTP (trap 7, collecting event 378), 17 Jun.–3 Jul. 2003 (no. CEC 330); 1 ♂, Lule Lappmark, Sorsele, Vindelfjällen NR, 6 km W of Ammarnäs, herb-rich subalpine birch forest, MT, MCJ leg., 7 Jul.–12 Aug. 2009 (no. CEC 331). 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. : Published as part of Jaschhof, Mathias & Jaschhof, Catrin, 2017, New species of Aprionus (Diptera, Cecidomyiidae, Micromyinae) from Sweden and other parts of the Palearctic region, pp. 1-38 in European Journal of Taxonomy 378 on pages 19-20, DOI: 10.5852/ejt.2017.378, http://zenodo.org/record/3838627 : {"references": ["Jaschhof M. & Jaschhof C. 2009.
