Cis bituberculatus was described based on two males and one female ( Roubal 1912 ). Two male syntypes are deposited in SNM; the deposition of the third syntype is unknown to me. It is clear that both syntypes , characterised by a finely pubescent pronotum and a pair of small tubercles on the anterior pronotal margin, are conspecific with Cis glabratus . In the original description, Roubal (1912) treated the specimen with smaller pronotal tubercles as female, what is likely a mistake.The females of Cis glabratus have anterior margin of pronotum regularly rounded without the tubercles. The specimen formerly considered to be a female is, in fact, a less developed male. One of the syntypes deposited in SNM ( Figs 1–4 ) is designated here as lectotype . Roubal (1912) compared Cis bituberculatus only with C. jacquemartii Mellié, 1849 and C. nitidus (Fabricius, 1792) (now C. castaneus Herbst, 1793 ), while C. glabratus was not mentioned. A probable explanation is that the identity and position of C. glabratus were not precisely known at that time. Cis glabratus was usually listed as a synonym or variety of C. jacquemartii , and the characteristic structures, such as fine setae on the pronotal surface and small tubercles on the anterior pronotal margin in males, were not mentioned in the widely used literature (e.g. Schilsky 1900 ; Reitter 1901 , 1911 ). FIGURES 1–4. Cis glabratus Mellié, 1849 (lectotype of C. bituberculatus Roubal, 1912 ). 1—dorsal view; 2—lateral view; 3—frontal view; 4—labels. Roubal (1937) discovered the primary homonymy of his species with C. bituberculatus Gorham, 1886 from Mexico , and proposed the new replacement name C. bituberculosus Roubal, 1937 . Based on the examination of syntypes of C. bituberculatus , I propose the following new synonymy: Cis glabratus Mellié, 1849 = Cis bituberculatus Roubal, 1912 , syn. nov. = Cis bituberculosus Roubal, 1937 , syn. nov.
