Definition: Monophyletic clade based on 12S RNA + 16S rRNA + COI + 18S rRNA
+ 28S rRNA genes phylogeny. The least inclusive clade containing Chlorophorus annularis
(Fabricius, 1787), but not including Anaglyptus mysticus (Linnaeus, 1758), and Clytus arietis
(Linnaeus, 1758).
Subordinated taxa:
3.1. Subtribe Plagionotina, subtrib. nov.
Type genus: Plagionotus Mulsant, 1842: 71 [47]
Description: Body subcylindrical, weakly elongated, slightly dorsoventrally
flattened, with a hair pattern of spots and transverse stripes. Head short. Forehead narrowed
with closely spaced antennae bases. Antennae elongated, reach at least the middle of elytra.
Antennomeres often with solid posterior spine. Pronotum subspherical, transverse. Prosternal
process very wide. Elytra elongate, parallel, with longitude sutural carinae (North American
genera) or without it (Eurasian genera), apically truncated. Legs elongated. Femora gradually
thickened posteriorly, often apically acutely spined.
Diagnosis: Body slightly dorsoventrally flattened; pronotum transverse; prosternal
process very wide.

3.2. Subtribe Chlorophorina, subtrib. nov.
Type genus: Chlorophorus Chevrolat, 1863: 290 [10]
Description: Body significantly elongated, subcylindrical, with a hair pattern of spots
and transverse stripes. Head slightly elongated, clypeus well developed. Forehead narrowed
with closely spaced antennae bases. Antennae elongated, reach the second third of elytra or
longer. Antennomeres often with a large posterior spike or long process. Pronotum
subspherical, oblong. Prosternal process narrow. Elytra elongate, parallel, apically truncated
or rounded. Legs very elongated. Femora gradually thickened posteriorly.
Diagnosis: Head slightly elongated; clypeus well developed; prosternal process
narrow.
