Data_A New Species of Hyporheic Corethrella Coquillett from North America (Diptera: Corethrellidae)

Larval and adult data sets from a study conducted on Bull Creek, MO (southwest of Ozark, MO) from October 2017 to October 2018 by Nathan C. Dorff. Accompanies A New Species of Hyporheic Corethrella Coquillett from North America (Diptera: Corethrellidae).

The larva of Corethrella kipferi sp. n. occupies hyporheic habitat regardless of perennial surface flow in two close locales in the Ozark Mountains in Christian County, Missouri, USA. This represents the first capture and identification to species-level of Corethrella in the hyporheic zone and the only description of a larva from the rotunda species group. The larvae appear to be obligate hyporheic dwellers with no representatives collected in concurrent benthic samples from riffles of the perennial stream. The female adult and fourth instar larva are described and illustrated using photomicrographs and line drawings. We describe what is known of the natural history of the new species and infer its phylogenetic placement within the genus.

本数据集由内森·C·多夫（Nathan C. Dorff）于2017年10月至2018年10月，在美国密苏里州奥扎克地区西南部的布尔溪开展研究时采集整理，包含幼虫与成虫相关数据。本数据集配套发表论文《来自北美潜流生境的幽蚊属（Corethrella）新种》，该论文涉及的分类类群为双翅目（Diptera）幽蚊科（Corethrellidae）。
美国密苏里州克里斯琴县奥扎克山脉两处邻近区域中，基普弗幽蚊（Corethrella kipferi sp. n.）的幼虫栖息于潜流生境（hyporheic habitat），不受该区域是否存在常年地表径流的影响。此项研究首次在潜流带（hyporheic zone）捕获并鉴定出幽蚊属物种（鉴定至物种水平），同时也是目前仅有的一次对rotunda物种群幼虫的正式形态描述。该幼虫为专性潜栖生物，未在同期采集的常年溪流急流浅滩的底栖样本中发现任何个体。本研究通过显微照片与线条绘图，对该新种的雌性成虫及4龄幼虫进行了形态描述与图解说明。此外，本研究梳理了该新种目前已知的自然史信息，并推断其在幽蚊属内的系统发育位置。
