摘要

Twelve Chinese species of genus Dexia Meigen are studied, including 5 new species (in litt. ), two new synonyms, Sumatrodexia incisuralis Baranov, syn. n. is revised to Dexia caldwelli Curran, Phasiodexia formosana Townsend, syn. nov. to Dexia flavida (Townsend), 3 newly recorded species to China: D. extendens Walker, D. fulvifera Roder and D. ventralis Aldrich. A key to 15species and a list of 7 known species of Dexia are given, and the monophyly of Dexia is supported.%寄蝇科的卵或幼虫寄生于其他昆虫,是农林业害虫的重要天敌.长足寄蝇属主要寄生于土壤中生活的鞘翅目金龟子总科幼虫体内,分布于古北区,东洋区和非洲区,已知约40余种.本属在东亚和东洋区,原始文献分散,描述简单,缺乏系统研究.在对该地区产长足寄蝇族系统研究过程中,作者整理、鉴定出中国产长足寄蝇属13种,包括5新种(另文发表),2新异名:Sumatrodexia incisuralis Baranov,syn.n.被订正为卡德长足寄蝇Dexia caldvvelli Curran;Phasiodexia formosana Townsend,syn.nov.为黄长足寄蝇Dexiaflavida(Townsend),3中国新记录种:巨长足寄蝇Dexia extendens Walker,广长足寄蝇D.fulvifera Roder和腹长足寄蝇D.ventralis Aldrich,报告了7种已知中国产长足寄蝇,并编制了该属15种检索表.
