12种双棘长蠹属昆虫(鞘翅目:长蠹科)的鉴定特征
Identification and key characteristics of 12 species of Sinoxylon(Coleoptera:Bostrichidae)
摘要
Abstract
[Aim]Sinoxylon spp.(non-Chinese),considered quarantine pests in China,are prohibited from entering the country.However,species of Sinoxylon are morphologically similar and often difficult to identify accurately.This study seeks to address the difficulty arising from a lack of images that document the morphological features of these beetles to facilitate their quarantine identifi-cation,in order to servie as a reference for their quarantine identification.[Method]This paper analyzes 12 species intercepted from imported logs and collected in China,including Sinoxylon unidentatum,S.anale,S.ruficorne,S.sudanicum,S.epipleurale,S.transvaalense,S.divaricatum,S.ceratoniae,S.senegalense,S.crassum,S.succisum,and S.tignarium.The analysis focused on the effects of the length of the body,side profile,shape of the antenna,dual teeth,setae,and marginal tubers on elytron declivity,a-mong other key characteristics.[Result]The body length of 12 species of beetles was found to vary significantly,ranging from 4.0-8.6 mm.Herein,the lateral view of an adult is presented.The antennae of these beetles can be categorized into three-fingered and trilobite types,based on the ratio of the club length to the width of the second segment.The morphology and position of the two spines also varied.The setae on the elytra declivity can be classified into three types,namely bowed,erect,or hairless.Combined with their body length and other features,this work provides a key for the identification of these 12 beetle species.[Conclusion]The antennae types of the Sinoxylon beetles,the morphology and location of the double spine,and the types of setae on the slope can serve as the primary characteristics of these beetles.关键词
