DIAGNOSIS. Body of moderate size, rarely small; antennae reddish at basal half and darkened apically, in males reaching inner end of central oblique elytral stripe, in females slightly extend beyond inner end of oblique humeral stripe; prothorax more or less globular, with evenly rounded sides; male prothorax about as long as wide, female prothorax slightly transverse; anterior and posterior margins with dense yellow pubescence; pronotum convex, regular cells of honeycomb sculpture are distinct in females only; male pronotum consists of very dense fine grainy sculpture with obliterated or conjugated cells; erect pronotal setae short; scutellum with dense yellow pubescence; male elytra about 2.5 times longer, than humeral width, female elytra – about 2.4 times; each elytron with 4 dense yellow setae stripes: short oblique humeral setae stripe about always well developed, wide and dense, as well as apical stripe; long oblique central stripe never protruding anteriorly along suture; transverse postmedian stripe also relatively wide; posterior femora usually do not reach elytral apices (but sometimes do); body length in males: 7.5–13 mm; in females: 8.5–15 mm.

DISTRIBUTION. Siberian species known from north-east of European Russia: Kirov Region (Vyatka River Valley), Perm Region (Kamenka), Komi Republic (Ukhta environs, Maldy in Polar Urals), Middle Urals (Bashkirsky and Ilmen natural reserves); Orenburg Region and eastwards all over Siberia from south to the far north (known from the mouth of Indigirka valley, 71°N), including Khabarovsk Region and Northern Sakhalin Island; must occue in Kunashir Is., though no specimens are known up to now; the situation in Primorye Region is not clear; Plavilstshikov (1940) did not mention it in the description of the species area, but it is shaded on the corresponding map; Cherepanov (1982) did not mention Primorye, while in the key to Cerambycidae of the Far East (Cherepanov, 1996) Primorye is placed under a question mark; C. arietoides from Primorye is unknown to the author; corresponding specimens are absent in the collection of N.N. Plavilstshikov; the species was found in Eastern Kazakhstan, as well as in Korea, Japan (Hokkaido) Mongolia and Northern China.
