Clytini, trib. sensu nov.
The clade consists of two subclades: 1) Neoclytus + Cotyclytus; 2) Brachyclytus, Clytus
+ Cyrtoclytus + Clytobius and Xylotrechus. Both subclades are well separated from each
other with a high level of branches support (SH=1.00 and SH=0.89 respectively), which
means that they should be considered as separate subtribes: Neoclytina, subtrib. nov. and
Clytina, subtrib. nov. Genus Neoclytus Thomson, 1860 is polyphyletic. At least Neoclytus
mucronatus (Fabricius, 1775) belongs to a separate genus and distantly related to Cotyclytus
curvatus (Germar, 1821). Clytus also is polyphyletic. Clytus ruricola (Olivier, 1795) is
related to Cyrtoclytus Ganglbauer, 1881. Clytobius davidis (Fairmaire, 1878) represents the
separate clade related to Clytus. Xylotrechus is totally polyphyletic and represented by at least
three distinct clades: 1) Xylotrechus chinensis Chevrolat, 1852 + Xylotrechus villioni Villard,
1892; 2) Xylotrechus grayii (White, 1855); 3) Xylotrechus s.str. All of them should be
considered as independent genera. Although, it is likely that Xylotrechus s.str. (the third
clade) also, nonmonophyletic. In this paper, I accepted statement that Xylotrechus s.str. is
monophyletic in general.

Chlorophorini, trib. nov.
The clade consists of four subclades: 1) Epiclytus yokoyamai (Kano, 1933); 2) Rhaphuma
elongata Gressitt, 1940; 3) (Plagionotus + Echinocerus) + (Megacyllene + Placosternus); 4)
Chlorophorus, Demonax, Clytoleptus, Sarosesthes, Rhaphuma, Clytocera, Rhabdoclytus.
First two subclades are basal and independent of the others. The last two subclades represent
crown species rich part of phylogenetic tree. Both clades well separated with strong branches
support (SH=0.99 and SH=0.82 respectively) and have crucial morphological differences. I
propose recognize them as subtribes: Plagionotina, subtrib. nov. and Chlorophorina,
subtrib. nov. Echinocerus is a separate genus independent of Plagionotus s.str. The genus
Placosternus, syn. nov. is part of the genus Megacyllene. Genus Chlorophorus is completely
polyphyletic and clearly divided on three distinct unrelated lineages: 1) Chlorophorus s.str.
(Chlorophorus annulatus (Hope, 1831), Chlorophorus varius (O.F. Müller, 1766),
Chlorophorus signaticollis (Laporte de Castelnau & Gory, 1841), Chlorophorus
anticemaculatus Schwarzer, 1925); 2) Chlorophorus sartor (O.F. Müller, 1766); 3)
Chlorophorus diadema Motschulsky, 1853; 4) the rest 9 studied species of Chlorophorus.
Chlorophorus sartor is an ally of Rhaphuma gracilipes (Faldermann, 1835), nested within
the same clade with Demonax (Demonax substitutus Gressitt, 1951 + Demonax bidenticornis
Hayashi, 1974) and Rhabdoclytus acutivittis (Kraatz, 1879). Chlorophorus diadema belongs
to the clade with Demonax transilis, Clytoleptus albofasciatus (Laporte & Gory, 1835),
Sarosesthes fulminans (Fabricius, 1775) and Rhaphuma xenisca (Bates, 1884). Genus
Rhaphuma is completely polyphyletic.
