Danilevsky A.N. Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences Leninsky prospect, 33, Moscow 119071 Russia e-mail: [email protected] ORCID 0000-0001-8079-3343 Key words: Coleoptera, Cerambycidae, taxonomy, ICZN, new synonym, restored name. Abstract. Several new synonyms are proposed. A long-proposed unacceptable synonymy has been wrongly proposed again as a new one. The composition of one subgenus has been expanded. The correct spelling of one species name and one subgeneric name have been restored. One name is recognized as a type species name of the genus. Introduction Cerambycidae is one of the most studied families of beetles, but its taxonomic nomenclature continues to be updated annually. Several taxonomy modifications and remarks are proposed below. One old species name is accepted as available and valid. Results 1. The type species of Pachyta Dejean is Leptura octomaculata Schaller, 1783 [as “L. octomaculata Fabricius, 1792”] (= L. cerambyciformis Schrank, 1781), by subsequent designation in Westwood (1838: 41). L. cerambyciformis Schrank, 1781 is currently included in Pachytodes Pic, 1891. So, Pachyta Dejean, 1821 becomes the correct name for Pachytodes Pic, 1891 (Pachyta Dejean, 1821 = Pachytodes Pic, 1891), and the species previously placed in Pachyta would be included in Argaleus LeConte, 1850. This would lead to a great instability since both Pachyta and Pachytodes have been used a lot in the literature. A Case could/should be submitted to the ICZN to conserve the usage M.L. Danilevsky 605 of Pachyta and Pachytodes by requesting the suppression of the type species designation by Westwood (1838) and adoption of Leptura quadrimaculata Linnaeus, 1758 as type species of Pachyta Dejean, 1821, proposed by Thomson (1864), which has been accepted in the literature. The new name Prorhagium Krajčik, 2025b (type species Cerambyx lamed Linnaeus 1758) is superfluous. New synonym must be established: Pachyta Dejean, 1891 = Prorhagium Krajčik, 2025b, syn. nov. I am very grateful to Dr. Serge Laplante for consultations. 2. According to Plavilstshikov’s (1934: 169) note on Rhopalopus: “Rh. heteromorphus Jank. 1932 = nadari Pic, 1894”. I was unable to detected a publication by Jankowski (1932). Most probably it was not ever appeared. So, the name “heteromorphus” was firstly published by Jankowski (1934: 95) as a probable synonym of Rh. nadari Pic, 1894: “Остается, поэтому, провизорно определить нашего усача, как R. nadari со знаком вопроса, … ” (It remains apparently identified our longhorn-beetle as R. nadari with a question mark). Each such identification of the species inside its detail description by Jankowski (1932: 96, 98) was accompanied with question mark: “Rhopalopus nadari Pic (?)” or “R. nadari (?)”. So, the name Rhopalopus heteromorphus Jankowski, 1934 was not definitely accepted by its author as a synonym, and it does not meet the conditions of the Art. 11.6. (ICZN 1999) - Ropalopus heteromorphus (Jankowski, 1934) is a valid name of a species distributed in Kirgizstan, Uzbekistan and Kazakhstan. The species was described once more as Ropalopus mali Holzschuh, 1993; Ropalopus heteromorphus (Jankowski, 1934) = Ropalopus mali Holzschuh, 1993, syn. nov. I am very grateful to Dr. Boris Korotyaev for consultations. 3. Leioderus Redtenbacher, 1845: 110 was described together with a single species L. testaceus Redtenbacher, 1845:153 [footnote] (Art. 13.4. Combined description of new genus-group taxon and new species). So, L. testaceus Redtenbacher, 1845 (= Leioderes kollari Redtenbacher, 1849) is a type species of Leioderus Redtenbacher, 1845, see Danilevsky (1988: 215). Sama (2000) agreed that Leioderus L. Redtenbacher, 1845: M.L. Danilevsky 606 110 was actually described alongside the species Leioderus testaceus Redtenbacher, 1845: 153 (mentioned in a footnote). However, for dubious reasons, he considered it inappropriate to treat both of these names as valid and regarded Leioderus testaceus Redtenbacher, 1845 as unavailable. Sama (2000) cites ICZN 12.2.5, arguing that a new generic name must necessarily include at least one available specific name; however, Articles 67.2.2 and 69.3 of the Code clearly contradict this. 4. According to Karpinski et al. (2025: 7): Lamiini Latreille, 1825 = Dorcadionini Swainson, 1840, “syn. nov”. The unacceptable synonyms were already published long ago by Sama (2008: 233). 5. Dorcadion rufogenuum Reitter, 1895 is used to be published with a wrong spelling - “rufogenum”: Pic (1909: 99), Plavilstshikov (1932: 192; 1958: 278), Breuning (1946: 129; 1962: 432; 1966: 751), Lobanov et al. (1982: 263), Danilevsky (1993: 48; 2002: 2; 2010: 252; 2020: 443; 2023: 170), Hua (2002: 205; 2024: 680), Danilevsky & al. (2005: 137), Hua et al. (2009: 454), Toropov, Milko (2013: 12) and others. A correct spelling “rufogenuum” was published by Gressitt (1951: 335), Lin & Tavakilian (2019). 6. Eodorcadion (Arenodorcadion Karpiński, 2025: 9) was proposed with type species: Neodorcadion egregium Reitter, 1897 for a single species E. (Ar.) egregium (Reitter, 1897). Besides one more species must be included in E. (Arenodorcadion): E. (Ar.) brandti (Gebler, 1841b). It is so close to E. (Ar.) egregium, that transitional specimens are known in China from the environs of Ulungur lake. So, E. (Ar.) egregium (Reitter, 1897) could be regarded as a subspecies of E. (Ar.) brandti (Gebler, 1841). 7. The taxonomy position of Phytoecia malachitica Lucas, 1847 rests unadequate. Traditionally the species was regarded as a member of the nominative subgenus as Ph. (s. str.) malachitica Lucas, 1847 (Breuning, 1951: 362; 1966: 751; Löbl & Smetana, 2010: 307; Danilevsky, 2020: 443), or as Ph. (Opsilia) malachitica Lucas, 1847 (Reitter, 1911: 270; Villiers, 1946: 140), or as Opsilia malachitica M.L. Danilevsky 607 (Lucas, 1847) (Vives, 2000: 488; Jeremías & Pérez De Gregorio, 2024: 191). At last it was included in a new artificial subgenus Ph. (Metallicophytoecia Özdikmen, 2025: 1819) - type species Leptura caerulea Scopoli, 1772, despite the fact that Phytoecia malachitica has nothing in common with Ph. caerulea (Scopoli, 1772). The last position was supported by Lazarev (2025). In fact Ph. malachitica is quite unique and characterises by exceptional set of characters: undivided eyes, unicuspid mandibulae, black elytra densely covered with strongly shining green or bluish scales, male pygidium without emargination. The species deserves its own subgenus Ph. (Hoplotoma Perez Arcas, 1874: 151, nom. rest.) type species Phytoecia malachitica P. H. Lucas, 1847. REFERENCES Breuning S. 1951.
