Phymatodes infasciatus, an East Palaearctic species occuring in Russian Far East, China, Japan, and Korea, has been described from Shanghai environs as Pœcilium infasciatum by Maurice Pic in 1935 [▽].
According to Tatsuya Niisato, later described taxa Phymatodes vandykei Gressitt, 1935 and Phymatodes (Phymatodellus) ussuricus Plavilstshikov, 1940 are junior synonyms of this species [✧].
Larvae of P. infasciatus develop in thin branches of grapevine, creating galleries along twig initially in upper layer directly under bark, later along pith, plugged with fine frass.
They then overwinter in wood and pupate in pupal cells created in the wood during the next late spring. Life-cycle 1 year. Adults, active from June to August, can be found and beaten from the host plant [✩].
