Chlorophorus fainanensis Pic, 1918 is redescribed. Four species, C. coniperda Holzschuh, 1992, C. diversicolor Holzschuh, 2016, C. orbatus Holzschuh, 1991 and C. pinguis Holzschuh, 1992 are newly reported from China. A new synonymy, Chlorophorus arciferus (Chevrolat, 1863) = Chlorophorus semisinuatus Pic, 1949, syn. nov. is proposed.
Cerambycinae, Clytini, longhorn beetle, new records, new synonym, taxonomy
The genus Chlorophorus was established by Chevrolat in 1863 with the type species Callidium annulare Fabricius, 1787. It is distributed in the Old World, mainly in the Oriental and Palearctic regions. It is the largest genus in the tribe Clytini, consisting of 299 species/subspecies worldwide (
Prior to our study, 83 species/subspecies had been recorded in China (
Pictures of adult morphology are composites taken using a digital camera Canon 7D with HELICON REMOTE (HeliconSoft, Ukraine). For detailed examination, male genitalia were extracted from specimens, cleared in 10% NaOH, and stored in ethanol 75%. The male genitalia were imaged using a Leica M205A stereomicroscope.

This species is similar to C. sappho Gressitt & Rondon, 1970. Chlorophorus sappho can be distinguished from this species mainly by the larger body size; yellow body coloration; meso- and metafemora finely carinate externally; metatibia slightly sinuate and feebly carinate; and elytral apex toothed at the external edge.
