Anacharis norvegica Mata-Casanova & Pujade-Villar 2018

Anacharis norvegica Mata-Casanova & Pujade-Villar, 2018 Diagnosis (n = 1). Belongs to the A. immunis species group. Similar to A. ensifer in generally having a largely sculptured mesoscutellum (largely smooth in A. immunis). Different to A. ensifer by having its mesoscutellum covered with reticulate-foveate sculpture resulting in smaller foveae (larger foveae in A. ensifer). The circumscutellar carina is less distinct and not flanged upwards posteriorly (usually distinctly flanged upwards, appearing in lateral view like a posterodorsal tooth in A. ensifer and A. immunis). The dorsal margin of the mesopleural line is diffused by rugose sculpture of mesopleuron in its anterior half (dorsally well-defined mesopleural line in its anterior half in A. ensifer and A. immunis). Wrinkles on mesoscutum, especially in anteromedian area, strong, making the anteroadmedian signa distinct (less to no wrinkles and thereby less notable anteroadmedian signa in A. ensifer and A. immunis). Other material examined. Material without DNA barcode. Sweden • 1 ♀; Torne lappmark, Kiruna, Abisko Nationalpark, dry sparse alpine downy birch forest; 68.3539 ° N, 18.7822 ° E; ca 410 m a. s. l.; 21 Jul. - 7 Aug. 2003; Swedish Malaise Trap Project (Swedish Museum of Natural History) leg.; Malaise trap; NHRS - HEVA 000023145 (NHRS). Biology. Summer species, type series collected in July and August, as was the specimen studied here. Probably preferring boreal habitats. Distribution. Norway (locus typicus: Oppdal), Sweden. Collected in higher elevations from 400 (specimen studied here) to 900 m a. s. l. (type series). Remarks. Despite not having had a fresh specimen at hand for sequencing, we regard this species as different from A. ensifer due to the clear differences in sculpture of the mesoscutum, mesoscutellum and mesopleuron. The species was described from one locality in central Norway (Oppdal) (Mata-Casanova et al. 2018) and we found only one additional specimen from Abisko national park (Sweden) within the older dry-mounted specimens originating from all over Sweden (coll. NHRS) and Switzerland (coll. MHNG & NMBE). Our diagnosis was made as an amendment to the diagnosis by Mata-Casanova et al. (2018), considering the single specimen we had at hand as well as the data and illustrations given in Mata-Casanova et al. (2018). The fresh samples that we had access to were mainly collected in Germany and Belgium, with a few additions from Southern Norway. As we did not find more specimens of that species, we deem it possible that its distribution is limited to boreal habitats in the scandic mountains.
