Data from: Terrestrial arthropods of Steel Creek, Buffalo National River, Arkansas. II. Sawflies (Insecta: Hymenoptera: "Symphyta")

Background: This is the second 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 using twelve trap types – Malaise traps, canopy traps (upper and lower collector), Lindgren multifunnel traps (black, green, and purple), pan traps (blue, purple, red, white, and yellow), and pitfall traps – and Berlese-Tullgren extraction of leaf litter. New information: We provide collection records for 47 species of "Symphyta" (Insecta: Hymenoptera), 30 of which are new state records for Arkansas: (Argidae) Sterictiphora serotina; (Cimbicidae) Abia americana; (Diprionidae) Monoctenus fulvus; (Orussidae) Orussus terminalis; (Pamphiliidae) Onycholyda luteicornis, Pamphilius ocreatus, P. persicum, P. rileyi; (Pergidae) Acordulecera dorsalis, A. mellina, A. pellucida; (Tenthredinidae) Caliroa quercuscoccineae, Empria coryli, Hoplocampa marlatti, Macrophya cassandra, Monophadnoides conspiculatus, Monophadnus bakeri, Nematus abbotii, Neopareophora litura, Pachynematus corniger, Paracharactus rudis, Periclista marginicollis, Pristiphora banski, P. chlorea, Strongylogaster impressata, S. remota, Taxonus epicera, Thrinax albidopictus, T. multicinctus, Zaschizonyx montana; (Xiphydriidae) Xiphydria tibialis.

背景：本系列研究论文共多篇，本文为第二篇，记录了阿肯色州布法罗国家河沿岸斯蒂尔溪营地附近区域密集陆生节肢动物调查中采集的标本。本次调查历时八个半月，共使用12类诱捕工具：马氏陷阱（Malaise traps）、冠层陷阱（canopy traps，配备上下两层收集器）、林德格伦多漏斗陷阱（Lindgren multifunnel traps，分为黑、绿、紫三种颜色）、盘式陷阱（pan traps，涵盖蓝、紫、红、白、黄五种颜色）以及地面诱捕陷阱（pitfall traps），同时采用伯莱塞-图尔格林抽提法（Berlese-Tullgren extraction）处理落叶样本以提取节肢动物。

新进展：本研究共记录广腰亚目（Symphyta，昆虫纲Insecta：膜翅目Hymenoptera）47个物种的采集记录，其中30种为阿肯色州州级新分布记录，具体类群如下：
（三节叶蜂科Argidae）Sterictiphora serotina；
（锤角叶蜂科Cimbicidae）Abia americana；
（松叶蜂科Diprionidae）Monoctenus fulvus；
（褶翅蜂科Orussidae）Orussus terminalis；
（扁叶蜂科Pamphiliidae）Onycholyda luteicornis、Pamphilius ocreatus、P. persicum、P. rileyi；
