  • 摘要:

    本研究根据从云南省高黎贡山(保山市段)洞穴采集的伪蝎标本,整理并描述了阿伪蝎科安伪蝎属一新种,即禾木安伪蝎(Anatemnus hemuensis sp. nov.)。该属的主要特征在于触肢粗壮,腿节和膝节多具明显颗粒,不动指上的听毛it位于指的中部,听毛esbest之间的距离大于isbist之间的距离,背板不完全分隔。世界已知22种(不包含本文新种),主要分布于非洲和美洲,中国仅知3种:任氏安伪蝎(A. reni Gao & Zhang, 2016)、宝安伪蝎(A. orites (Thorell, 1889))、潮州安伪蝎(A. chaozhouensis Hu & Zhang, 2012)。该新种背甲的眼部已经完全退化,依据该特征,很容易区分,除分布于澳大利亚的2个物种(A. subvastus Alexander, Burger & Harvey 2014,采集自地下环境;A. cavernicola Berier, 1976,采集自Jump Up Cave),然后依据步足I和步足IV跗节端部具有极其弯曲的刚毛将新种与这两种进行区分。新种触肢转节具有1个明显的背突,1.7倍长于宽(0.47/0.28 mm),腿节2.8倍长于宽(0.90/0.32 mm),膝节2.2倍长于宽(0.82/0.37 mm),螯肢指明显短于具柄的螯掌;前螯螯掌具有4根刚毛,基部2根末端齿状,盔状物具有5个分叉,鞭状毛4根,末端2根齿状;口下突有5根顶端毛和1根亚中毛。在文中提供了新种的整体图以及特征图,另外还提供了中国安伪蝎属的分种检索表,所检视的标本保存于西华师范大学生命科学学院昆虫标本馆。
