摘　　要：江门海关从冈比亚进境的刺猬紫檀木原木中检出活体长蠹科昆虫。通过显微形态特征的观察和测量,对该虫进行了物种鉴定。经形态特征鉴定,该虫为小楔双棘长蠹。该虫的形态特征与近似种的主要区别:斜面毛被稀疏、不太明显,近缝角处竖立短直;缝侧齿基部不粗糙;斜面侧上缘有3对胝状的痕迹显现。该虫在我国尚无分布记录,为国内口岸首次截获。该虫一般随着原木、木制品及木质包装进行远距离传播,一旦传入我国,将对我国的农林安全造成巨大威胁,各口岸须加强对进境原木、木制品及木质包装的检验检疫。A specimen of an unidentified,live bostrichid beetle was detected by Jiangmen Customs on Pterocarpus erinaceus logs imported from Gambia.The species identification was carried out by observation and measurement of micro-morphological characteristics.This insect was identified as Sixnoxylon cuneolus(Coleoptera;Bostrichidae).The main difference between S.cuneolus and similar species is that the hair on the apical declivity of elytra is sparse and not obvious,but it was erect short hair at the apices;the base of the teeth on the suture side was not rough;there were three pairs of callose marks on the upper edge of the apical declivity.So far,there have been no reports of occurrence of this species on China's Mainland.S.cuneolus generally spreads over long distances with logs,wood products and packaging.The species poses substantial threat to the agricultural and forestry sectors in China.The quarantine inspection of imported logs,wood products and wooden packaging at ports should be made aware of this potential threat.
