Fieber’s monograph “Die Europäischen Hemiptera” was published in two parts, in 1860 and 1861. The original description of Cylindrostethus is in the first part. Therefore, all mentions of “1861” in the original publication by Floriano et al. (2024) should read “1860”. The correct reference should read: Fieber FX (1860) Die Europäischen Hemiptera. Halbflüger. (Rhynchota: Heteroptera): i–vi, 1–112. Carl Gerold’s Sohn, Wien. The authors thank Franco Faraci (Museo Civico di Storia Naturale di Verona, Italy) for alerting them about the date issue.
