Body length 4.2–5.0 mm, maximum body width 2.6–3.1 mm. Holotype: body length 4.7 mm, maximum body width 3.0 mm. Body. Overall shape in dorsal view oval, elytral edge evenly rounded from base to apex. Head. Clypeal edge lateral to clypeal teeth lacking emargination (Fig. 4C), head margin at clypeogenal suture of females slightly protruding. Dorsal parts of eyes semi-ovoid, separated by an interocular space of about 3.9 times eye width. Pronotum. Pronotal width to length along midline ratio 1.9, lateral pronotal edge sharply defined throughout, pronotal pubescence short and fine, pronotal basal portion along midline lacking fine longitudinal depression. Elytra. Elytral maximum width to length along suture ratio 1.0, elytral outline moderately convex in lateral view, elytral pubescence short and fine, elytral surface between punctures appearing glossy, at most with ill-defined microsculptures (Fig. 12B), basal elytral pit slightly wider than stria 10 and shallow (Fig. 11D), basal surface of pseudepipleuron with irregularly distributed more or less defined punctures (Fig. 11E), interstriae 3–5 on basal fifth with scattered unaligned punctures. Legs. Profemoral anterior surface flat, male metatibial apicointernal tooth approximately in line with posterior tibial edge. Pygidium. Pygidial surface along midline with punctures absent or distinctly more scattered than rest of discs, at least basally, pygidial surface along basal groove smooth between punctures (Fig. 8A), pygidium of female depressed apically. Aedeagus. Left paramere apex truncated apically, distinctly angular externally (Fig. 9B). Female genitalia. Spermatheca with two apodemes basally. Etymology. The specific epithet for this species is the masculine nominative Latin adjective meaning “boiling hot” or “fiery” in reference to the type locality, which is near an old composite volcano.
