Abstract

The genus Speiser, 1928 (Diptera: Asilidae) is a fuzzy-looking assassin fly, and adults have only been observed in autumn and winter. Currently containing four described species, this genus is readily distinguished from other Chinese asilids by the presence of two crossveins. Through integrative taxonomic analysis of over 200 specimens from multiple Chinese provinces, we combined morphological assessment with DNA barcoding and four species delimitation methods (ABGD, ASAP, mPTP, and GMYC). Four species are newly described: , , , and (the latter described solely from morphological examination of historical specimens). Genetic analyses revealed distinct barcoding gaps, with an interspecific distance of 1.38-7.07% versus an intraspecific distance of no more than 0.92%. We revised the generic diagnosis, provided a distribution map, and a revised key to all known species of .

摘要

斯派泽属（Speiser，1928年）（双翅目：盗虻科）是一种外观模糊的盗虻，仅在秋冬季节观察到成虫。该属目前包含四个已描述的物种，通过存在两条横脉很容易与其他中国盗虻区分开来。通过对来自中国多个省份的200多个标本进行综合分类分析，我们将形态学评估与DNA条形码以及四种物种界定方法（ABGD、ASAP、mPTP和GMYC）相结合。新描述了四个物种：、、和（后者仅通过对历史标本的形态学检查进行描述）。遗传分析揭示了明显的条形码间隙，种间距离为1.38 - 7.07%，而种内距离不超过0.92%。我们修订了属的诊断，提供了分布图以及斯派泽属所有已知物种的修订检索表。
