Figures 71-80. Boreophilia neoinsecuta Klimaszewski: 71 habitus 72, 73 median lobe of aedeagus in lateral view 74 median lobe of aedeagus in dorsal view 75 male tergite VIII 76 male sternite VIII 77 female tergite VIII 78 female sternite VIII 79, 80 spermatheca. Scale bars: 1 mm (for habitus); 0.2 mm (remaining). Etymology. Derived from prefix neo- added to existing specific name insecuta , a closely related species. Diagnosis. Body moderately broad, subparallel, forebody moderately glossy, abdomen slightly more so (Fig. 71); length 3.2-3.5 mm; head, pronotum and abdomen except for its apex dark brown, elytra reddish brown, mottled with some darker spots, appendages reddish brown; antennomeres VIII-X subquadrate; pronotum ca. as long as elytra at suture, maximum width of pronotum ca. equals to maximum width of elytra. Male. Tubus of median lobe of aedeagus almost straight laterally, apex narrow and rounded, bulbus broad and with two elongate and posteriorly bent sclerites (Figs 72, 73), in dorsal view median lobe elongate oval (Fig. 74); tergite VIII arcuate apically (Fig. 75); sternite VIII elongate, parabolic apically (Fig. 76). Female. Spermatheca: capsule club-shaped, moderately long and rounded apically, with small apical invagination; stem sinuate and coiled posteriorly (Figs 79, 80); tergite VIII arcuate apically (Fig. 77); sternite VIII produced apically and pointed medially, antecostal suture slightly sinuate laterally (Fig. 78). Distribution. Nearctic, Canada: MB, YT: USA: AK. Collection data. Habitat: tundra, under rocks. Collecting methods: forceps/aspirator. Collecting period: May to July. Comments. Lohse, in Lohse et al. (1990) reported Boreophilia insecuta (Eppelsheim) in North America from AK, MB, YT, as a Holarctic species. However, these records represented a different and undescribed Nearctic species, which is here described as B. neoinsecuta sp. n. The two species, B. insecuta and B. neoinsecuta , have similarly shaped genitalia, which explains why they were confused. The true B. insecuta (Eppelsheim) was illustrated by Brundin (1954) , and here (Figs 82, 83), and has a distinctly dilated apex of median lobe of aedeagus in lateral view (Fig. 82), while it is narrower in B. neoinsecuta (Figs 72, 73), and the two sclerites of internal sac of median lobe of aedeagus are broader and differently shaped than those of B. neoinsecuta (Figs 82, 83). Spermathecae of both species are very similar in shape, but female sternite VIII in B. insecuta is apically rounded and truncate medially, while in B. neoinsecuta is triangularly produced apically and pointed medially (Fig. 78). Figures 81-83. Boreophilia insecuta (Eppelsheim) [specimen from Siberia, Russia]: 81 habitus 82 median lobe of aedeagus in lateral view 83 median lobe of aedeagus in dorsal view. Scale bars: 1 mm (for habitus); 0.2 mm (remaining). DNA Barcode data. Our data included two sequences of B. neoinsecuta paratypes, both from Alaska which grouped into BIN BOLD:ADR7545. These sequences are 0.00% distant from each other and BOLD reports they are 7.23% distant from their nearest neighbor.
