Data from: Terrestrial arthropods of Steel Creek, Buffalo National River, Arkansas. I. Select beetles (Coleoptera: Buprestidae, Carabidae, Cerambycidae, Curculionoidea excluding Scolytinae)

Background: The Ozark Mountains are a region with high endemism and biodiversity, yet few invertebrate inventories have been made and few sites extensively studied. We surveyed a site near Steel Creek Campground, along the Buffalo National River in Arkansas, 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 for eight and half months. New information: We provide collection records of beetle species belonging to eight families collected at the site. Thirty one species represent new state records: (Buprestidae) Actenodes acornis, Agrilus cephalicus, Agrilus ohioensis, Agrilus paracelti, Taphrocerus nicolayi; (Carabidae) Agonum punctiforme, Synuchus impunctatus; (Curculionidae) Acalles clavatus, Acalles minutissimus, Acoptus suturalis, Anthonomus juniperinus, Anametis granulata, Idiostethus subcalvus, Eudociminus mannerheimii, Madarellus undulatus, Magdalis armicollis, Magdalis barbita, Mecinus pascuorum, Myrmex chevrolatii, Myrmex myrmex, Nicentrus lecontei, Otiorhynchus rugosostriatus, Piazorhinus pictus, Phyllotrox ferrugineus, Plocamus hispidulus, Pseudobaris nigrina, Pseudopentarthrum simplex, Rhinoncus pericarpius, Sitona lineatus, Stenoscelis brevis, Tomolips quericola. Additionally, three endemic carabids, two of which are known only from the type series, were collected.背景：奥扎克山脉（Ozark Mountains）是一个特有性极高、生物多样性丰富的区域，但目前针对该区域的无脊椎动物调查记录匮乏，且鲜有点位被深入研究。我们针对阿肯色州布法罗国家河沿岸钢溪营地（Steel Creek Campground）附近的一处点位，开展了为期8.5个月的调查采样，采用12类诱捕装置——Malaise诱捕器（Malaise traps）、冠层诱捕器（canopy traps，包含上层与下层收集器）、Lindgren多角漏斗诱捕器（Lindgren multifunnel traps，分设黑色、绿色、紫色三种）、色盘诱捕器（pan traps，包含蓝、紫、红、白、黄五种）以及地面陷阱（pitfall traps），并结合Berlese-Tullgren萃取法处理样本。新进展：本研究提供了该点位采集到的隶属于8个科的甲虫物种的采集记录。其中31个物种为该州新记录物种：（吉丁甲科Buprestidae）Actenodes acornis、Agrilus cephalicus、Agrilus ohioensis、Agrilus paracelti、Taphrocerus nicolayi；（步甲科Carabidae）Agonum punctiforme、Synuchus impunctatus；（象甲科Curculionidae）Acalles clavatus、Acalles minutissimus、Acoptus suturalis、Anthonomus juniperinus、Anametis granulata、Idiostethus subcalvus、Eudociminus mannerheimii、Madarellus undulatus、Magdalis armicollis、Magdalis barbita、Mecinus pascuorum、Myrmex chevrolatii、Myrmex myrmex、Nicentrus lecontei、Otiorhynchus rugosostriatus、Piazorhinus pictus、Phyllotrox ferrugineus、Plocamus hispidulus、Pseudobaris nigrina、Pseudopentarthrum simplex、Rhinoncus pericarpius、Sitona lineatus、Stenoscelis brevis、Tomolips quericola。此外，本次调查还采集到3种特有步甲，其中2种此前仅以模式系列标本被报道过。
