The larva and pupa of the saproxylic Roger, 1857, the weevil species extremely rare in Europe, are described from Poland. It was reared from galleries in dead branches of a fallen spruce . The larval morphology is compared with available larval descriptions of other genera of the supertribe Conoderitae, namely, the Palaearctic , and the Nearctic and . The specific characters of the male and female postabdomen are described and illustrated, expressing the peculiar structure of endophallus and spermathecal duct, not seen in any other weevil species. A hypothesis regarding the mechanics of mating in this species is proposed. is recorded for the first time to occur in China.
1857年的食木象甲(Roger)幼虫和蛹,这种象甲在欧洲极为罕见,本文根据来自波兰的样本对其进行了描述。它是从一棵倒下的云杉死枝的虫道中饲养出来的。将该幼虫形态与其他Conoderitae超族属(即古北区、新北区等)已有的幼虫描述进行了比较。描述并说明了雌雄后腹部的特定特征,展现了其内生殖器和受精囊管的独特结构,这在其他象甲物种中未见。提出了关于该物种交配机制的假说。首次记录到其在中国出现。
