Data from: Terrestrial arthropods of Steel Creek, Buffalo National River, Arkansas. IV. Asilidae and other Diptera

Background: This is the fourth in a series of papers detailing the terrestrial arthropods collected during an intensive survey of a site near Steel Creek campground along the Buffalo National River in Arkansas. The survey was conducted over a period of eight and a half months in 2013 using twelve trap types, including Malaise and canopy traps, Lindgren multifunnel traps, and pan traps. New information: We provide collection records for 38 species of Asilidae and other Diptera, 7 of which are new state records for Arkansas: (Asilidae) Lasiopogon opaculus Loew, 1874; (Lygistorrhinidae) Lygistorrhina sancthecatharinae Thompson, 1975; (Stratiomyidae) Cephalochrysa nigricornis (Loew, 1866), Gowdeyana punctifera (Malloch, 1915), Sargus decorus Say, 1824; (Ulidiidae) Callopistromyia annulipes Macquart, 1855; and (Xylophagidae) Rachicerus obscuripennis Loew, 1863.

研究背景：本研究为系列论文的第四篇，详细记述了2013年在阿肯色州水牛国家河（Buffalo National River）沿岸斯蒂尔溪营地附近样地开展的密集陆生节肢动物采样调查中采集到的类群。本次调查于2013年历时8.5个月，共使用12类诱捕器，包括马氏诱捕器（Malaise traps）、冠层诱捕器（canopy traps）、林氏多漏斗诱捕器（Lindgren multifunnel traps）及盘式诱捕器（pan traps）。新发现信息：本研究共记录盗虻科（Asilidae）及其他双翅目（Diptera）昆虫38种，其中7种为阿肯色州新分布记录：（盗虻科（Asilidae））Lasiopogon opaculus Loew, 1874；（扁角蕈蚊科（Lygistorrhinidae））Lygistorrhina sancthecatharinae Thompson, 1975；（水虻科（Stratiomyidae））Cephalochrysa nigricornis (Loew, 1866)、Gowdeyana punctifera (Malloch, 1915)、Sargus decorus Say, 1824；（斑眼蝇科（Ulidiidae））Callopistromyia annulipes Macquart, 1855；以及木虻科（Xylophagidae）Rachicerus obscuripennis Loew, 1863。
