Measurements ♀ [min–max (average); N = 6]: FBL = 3.73– 3.94 (3.85); TL = 6.82–8.54 (7.92); HW = 0.91–0.96 (0.94); HL = 0.93–0.97 (0.95); HW/HL = 0.98–1 (0.99); PW = 1.2– 1.36 (1.28); PL = 1.2–1.26 (1.23); PW/PL = 1–1.09 (1.04); EW = 1.71–1.96 (1.84); EL = 1.59–1.74 (1.67); PW/ HW = 1.32–1.42 (1.36).
Head, mandibles, legs, last antennomeres, and last palpomeres dark-brown; first palpomeres and antennomeres, and elytra yellow; pronotum yellowish-brown; tergites and sternites with pale posterior margin.
Head from slightly wider than long, to slightly longer than wide; dorsally and ventrally glossy with few micropunctures and microsculpture of transverse waves, without coarse non-setiferous punctures; posterior angles indistinct with several setiferous punctures of medium and small-size. Eyes small size (EYL/HL = x = 0.45), from 1.27 to 1.35 times as long as temples (in lateral view) in males and from 1 to 1.16 times in females; distance between eyes about 1.24 times as long as length of eye in males and 1.41 times in females. Antennomeres 2 and 3 subequal in length; antennomeres 4 to 7 subequal in length; antennomeres 8 antennomeres 10 subequal in length; a11 from 1.62 to 2 times as long as a 10 in males and from 1.56 to 1.69 in females. Basal and parocular punctures usually single; posterior frontal puncture located posterior to temporal puncture; without small setose punctures between frontoclypeal punctures and anterior frontal punctures; ventral basal ridge rather straight, ends distinctly far from gular sutures; postgenal ridge present; postmandibular ridge reaching close to eye margin; PMP greatly reduced; nuchal ridge present laterally and dorsally, fused with infraorbital ridge; gula without microsculpture medially, gular sutures moderately separated in males and widely in females. Mandibles without dorsolateral groove; labrum with trapezoidal sclerotized region and entire apical margin; mentum with seta alpha only; penultimate labial palpomere markedly dilated apicad, apical palpomere distinctly narrower than previous and more or less subconical.
Pronotum slightly transverse, convex, evenly curved, with two PPDS, with an APP, with one SLSP; flexible postcoxal hypomeral extension (process) not interrupted by inferior line. Elytra evenly punctate, interspaces from about as long as, to three or five times as long as, diameter of punctures. Mesosternum with five macrosetae arranged in two rows medially.
Protibiae sexually dimorphic, with laterodorsal row of thick spines only in females. In males, mesotarsomeres 1–4 with pale adhesive setae, mesotarsomeres 1–3 with terminal plate. In females, mesotarsomeres 2–4 with pale adhesive setae without terminal plate. In both sexes, metatarsomeres 2–4 with pale adhesive setae, without terminal plate; metatarsomere 1 moderately longer than 5, metatarsomere 4 ventrally with apical margin bilobed.
Abdominal tergites III and IV with several rows of punctures of moderate size and density, without a sizeable impunctate area; tergite VIII emarginate medio-apically. Sternite III with basal transverse carina evenly converging at an obtuse angle; lateral tergal sclerites IX not dorsoventrally or laterally flattened. Male sternite VIII with rectangular V-shaped emargination medially (Fig. 14J); female sternite VIII with arcuate emargination medially; male sternite IX with obtuse emargination medially, its basal portion moderately longer than distal portion; male tergite X with U-shaped emargination medially (Fig. 12J); female tergite X with U-shaped emargination medially (Fig. 13J); ovipositor, its second gonocoxite with one macroseta medially.
Aedeagus as in Figure 11I, J; its total length 1.35–1.45.
Etymology: The species epithet is in honour of the Denmarkbased Carlsberg beer brewery, whose generous grants and beverages have facilitated much research in the Solodovnikov Lab. In addition, the male aedeagus resembles a bottle opener.
Distribution and habitat: Loncovilius carlsbergi is known only from the Magallanes and Chilean Antarctica Region of Chile, where it occurs in lowlands confined to Magellanic subpolar forest ecoregions. It is unknown how it was collected.
