Chevrolat (1860) established Ochraethes as a division of Clytus Laicharting, 1784 . Thomson (1861) designated O. circuliferus Chevrolat, 1860 (= O. sommeri (Chevrolat, 1835)) ( Fig. 1 ) as the type species of the genus. Later, Casey (1912) established Clytopsis to allocate C. nimbata Casey, 1912 (= C. dimidiaticornis ( Chevrolat, 1860) ( Figs. 13–14 ), the type species of the genus (see photograph of the holotype at Bezark 2019a). Casey (1912) separated Ochraethes from Clytopsis in his key by: “Basal process of the abdomen bluntly rounded or truncate at apex”, following to Ochraethes ; “Basal process acute”, following to Clytopsis . However, the abdominal intercoxal process in nearly all species of Ochraethes ( Figs. 3, 4, 7 ), which includes the type species of this genus, is identical or nearly identical to that of Clytopsis dimidiaticornis ( Figs. 5, 6 ). Furthermore, even in Ochraethes citrinus ( Chevrolat, 1860) , incorrectly considered as the type species of the genus by Casey (1912), the abdominal intercoxal process ( Fig. 7 ) is similar to that of Clytopsis dimidiaticornis ( Figs. 5–6 ). Actually, there is no difference allowing one to consider Clytopsis as a genus distinct from Ochraethes , and it is considered a junior synonymy. Also, the abdominal intercoxal process in males is often distinctly more slender and has the apex more acute in males than in females of some species of Ochraethes .
