Diagnosis: Nuchal ridge with small portion absent dorsally. Pronotum outline evenly curved. Elytra yellow or yellowish-brown with brown-black mark around mesoscutellum and suture. Protibiae sexually dimorphic, with laterodorsal row of thick spines only females. Aedeagus as in Figure 10O–Q View Figure 10 .
Description: Measurements ♂ [min–max (average); N = 5]: FBL = 3.98–4.34 (4.22); TL = 7.18–8.4 (7.59); HW = 0.93– 1.08 (1); HL = 1.03–1.23 (1.16); HW/HL = 0.88–0.91 (0.89); PW = 1.28–1.36 (1.32); PL = 1.25–1.36 (1.31); PW/ PL = 1–1.04 (1.02); EW = 1.74–1.92 (1.84); EL = 1.59–1.81 (1.7); PW/HW = 1.26–1.28 (1.27).
Measurements ♀ [min–max (average); N = 5]: FBL = 4.43– 4.67 (4.55); TL = 8.13–8.47 (8.3); HW = 1.18–1.22 (1.20); HL = 1.25–1.33 (1.29); HW/HL = 0.92–0.94 (0.93); PW = 1.44–1.49 (1.47);PL = 1.4–1.44 (1.42);PW/PL = 1.03– 1.03 (1.03); EW = 2–2.1 (2.05); EL = 1.78–1.9 (1.84); PW/ HW = 4.43–4.67 (4.55).
Head and pronotum brown-black with slight greenish, bluish, or golden overtones, with yellow margins; antennae, mouthparts, and legs yellow or yellowish-brown; elytra yellow with brown-black mark around mesoscutellum and suture; tergites and sternites dark reddish-brown with pale posterior margin.
Head elongate; dorsally and ventrally dull with metallic iridescence; with micropunctures and microsculpture of transverse isodiametric meshes, without coarse non-setiferous punctures; posterior angles indistinct with several setiferous punctures of medium and small size. Eyes small (EYL/ HL = x = 0.44), from 1.05 to 1.11 times as long as temples (in lateral view); distance between eyes about 1.24 times as long as length of eye in both sexes. Antennomere 3 moderately longer than antennomere 2; antennomeres 4 and 5 subequal in length; antennomeres 8 to 10 subequal in length; a11 from 1.52 to 1.7 times long as a 10 in males and from 1.4 to 1.48 in females. Basal and parocular punctures usually double; posterior frontal puncture located anterior to temporal puncture; with small setiferous punctures between frontoclypeal and anterior frontal punctures: ventral basal ridge in checkmark shape, almost united with gular sutures; postgenal ridge reduced; postmandibular ridge reaching close to eye margin; PMP greatly reduced; nuchal ridge present laterally and a liưle dorsally, not fused with infraorbital ridge; gula with conspicuous isodiametric microsculpture medially, gular sutures widely and equally separated in both sexes. Mandibles without dorsolateral groove; labrum with trapezoidal sclerotized region and entire apical margin; mentum with seta alpha only; penultimate labial palpomere only weakly dilated apicad, subequal in width with more or less subconical apical palpomere.
Pronotum about as wide as long, convex, evenly curved, with two PPDS, without APP, without SLSP; flexible postcoxal hypomeral extension (process) not interrupted by inferior line. Elytra evenly punctate, interspaces from about as long as, to four or five times as long as, diameter of punctures. Mesosternum with four macrosetae arranged in a row medially.
Protibiae sexually dimorphic, with laterodorsal row of thick spines only females. In males, mesotarsomeres 1–4 with pale adhesive setae, mesotarsomeres 1–3 with terminal plate. In females, mesotarsomeres 1–4 with pale adhesive setae, without terminal plate. In both sexes, metatarsomeres 2–4 with pale adhesive setae, without terminal plate; metatarsomere 1 shorter than 5, metatarsomere 4 ventrally with apical margin bilobed.
Abdominal tergites III and IV with only a few rows of coarse, sparse punctures, with large, impunctate area; tergite VIII not emarginate medio-apically. Sternite III with basal transverse carina evenly converging at obtuse angle; lateral tergal sclerites IX not dorsoventrally or laterally flaưened. Male sternite VIII with U-shaped emargination medially ( Fig. 14F View Figure 14 ); female sternite VIII without emargination; male sternite IX without emargination medially, with rounded apex, its basal portion shorter than distal portion; male tergite X with anterior margin subtruncate ( Fig. 12F View Figure 12 ); female tergite X medio-apically distinctly subacute to acute ( Fig. 13F View Figure 13 ); ovipositor, its second gonocoxite with three macrosetae medially.
Aedeagus as in Figure 10O–Q View Figure 10 ; its total length 1.25–1.31. Median lobe rod-like; internal sac with pair of long inverted L-shaped copulatory sclerites. Paramere distinctly produced over apex of median lobe; wider than median lobe; converging to a subrectangular apex; with small translucent peg setae; in lateral view almost straight, curved away from median lobe apically.
Etymology: Ŋe species epithet is derived from the Greek κανθαΡίς (kantharís; soldier beetles) and suffix -ειδής (-eid ḗ s; like), as the habitus resembles some species of the beetle family Cantharidae .
Distribution and habitat: Loncovilius cantharoides is known from Chile, from the Araucanía and Ñuble regions, and from the westernmost portions of the Neuquén and Río Negro provinces of Argentina. Ŋe species occurs from 800 to 1600 m of elevation; reported in the Araucaria - Nothofagus forests from the central and north-central portions of the Valdivian temperate forest ecoregion. It has been collected using Malaise, window, carrion and dung-baited pitfall traps, and sissing leaf liưer.
