Description. Male. Body robust, matt or with dull shine. Apex of frontoclypeus (frontoclypeal tooth) acute, vertically projected. Anterior margin of frontoclypeus not separated from the other surface of head. Genae weakly rounded, not sinuated. Head with wide transverse impression on each side between frontoclypeus and anterior margin of supraocular keels. Head widest at genal level. Ratio of maximal width of head to distance between eyes 1.5. Antennae short, with last apical antennomere reaching basal third of pronotum. Ratio of length (width) of antennomeres II–XI: 0.6(0.4): 0.4(0.4): 0.5(0.4): 0.5(0.4): 0.5(0.4): 0.4(0.4): 0.4(0.4): 0.4(0.4): 0.4(0.4): 0.3(0.3). Punctation of head moderately coarse and dense (puncture diameter 1.5–2× as long as distance among punctures). Mentum weakly shiny, with moderately coarse and dense punctation of weakly rasp-shaped smoothed punctures (puncture diameter 1.5–2.0× as wide as distance among punctures).

Pronotum transverse (1.5× as wide as long), widest little before middle, 1.5× as wide as head. Ratio of pronotal width at anterior margin, in middle and at base 5.0: 7.0: 6.5. Anterior margin of pronotum widely emarginate, base straight. Lateral margins of pronotum weakly rounded, not sinuated at base. Anterior angles of pronotum acute, narrowly rounded at apex, posterior angles obtuse. All margins of pronotum beaded, bead of anterior margin smoothed in middle. Disc of pronotum moderately convex, without depression in basal part; lateral margins of disc narrowly vertical in middle. Punctation of disc fine and sparse (puncture diameter 3–4× as wide as distance among punctures). Inner half of prothoracic hypomera punctate by moderately coarse, dense weakly rasp-shaped punctures (puncture diameter 1.5–2.0× as long as distance among punctures), outer half without punctation. Prosternal process laminar, strongly protruded, laterally acute, not beaded, with longitudinal depression.

Elytra regularly elliptical, moderately elongate (1.4× as long as wide), slightly convex, 2.3× longer and 1.1× wider than pronotum, 1.6× wider than head. Elytra without striae, with very fine, sparse punctation (puncture diameter 4.0–5.0× as wide as distance among punctures), apical half of elytra with almost invisible punctation. Epipleura smooth. Mesoventrite with long narrow, almost straight, vertical, regularly depressed bracket-shaped foveae. Metaventrite with coarse, moderately dense punctation along anterior margin of mesocoxae, remaining surface of metaventrite smooth.

Abdominal ventrite 1 with moderately coarse and dense punctation along basal margin of metacoxae, remaining surface of this and the other abdominal ventrites smooth. Lateral margins of abdominal ventrite 1 beaded only in anterior half, ventrites 2–5 not beaded.

Legs short. Anterior tibiae fossorial, wide, flattened, often depressed along dorsal surface of outer margin. Pro- and mesotibiae straight, metatibiae slightly curved. Ratio of femur/tibia/tarsus: 3.0: 2.5: 2.0 in fore legs, 3.5: 3.0: 2.5 in middle legs, and 4.0: 3.5: 3.0 in hind legs.

Body length 8.5 mm, width 4.0 mm.

Etymology. The name of the subspecies is derived from word volcano to demonstrate that it is spread only on volcanoes; adjective.

Comparative diagnosis. Calyptopsis capnisiformis volcanica subsp. nov. differs from the nominotypical subspecies in straight base of pronotum ( C. capnisiformis capnisiformis has bisinuate base), laminar, strongly protruded and laterally acute prosternal process ( C. capnisiformis capnisiformis is with rounded, weakly protruded, laterally rectangular prosternal process), often depressed along dorsal surface of outer margin of anterior tibiae (anterior tibiae of nominotypical subspecies are not depressed along dorsal surface of outer margin), elliptical elytra ( C. capnisiformis capnisiformis has trapezoidal elytra).
