胡氏华钮襀

英文:Sinacroneuria huzhengkuni Du & Huo sp. nov.

词源:该物种的命名是为了纪念胡政坤先生,一个来自贵州铜仁地区江口县的昆虫爱好者,提供了慷慨的帮助收集材料。

华钮襀属目前有11个种被发现和描述,模式种S. orientalis Yang&Yang,1995产自安徽黄山,是东洋界特有物种,分布于中国、日本和越南。该属在我国东部和中部是很常见的昆虫,在西南部却很少见。

襀翅目成虫生活在陆地,翅发达但不善飞行,多不取食,仅生活几周。稚虫大多生活在清洁水域中,以水中的蚊类幼虫等为食,对维持生态平衡及水体净化具有一定作用。同时,该类昆虫对水中的化学物质反应较为敏感,因此对水质要求极高,可用于检测水资源的污染状况。

华钮襀属新种的发现,也反映出了作为模式产地的亚木沟景区峡谷里的水质天然,无污染的现状。
