Abstract

Between 2015 and 2017, 58 ostracod taxa were collected at 30 locations in 111 samples from the hyporheic zone of surface streams in Texas, U.S.A. Six new species (Bradleycypris foresteri n. sp., Bradleystrandesia macula n. sp., Pseudocandona lordi n. sp., Indocandona rusti n. sp., Stenocypris sancari n. sp., Cyclocypris dalyana n. sp.) are described based on carapace and soft body parts. Additionally, 17 species and two genera (Vestalenula and Indocandona) are presented as new records for Texas, and Indocandona rusti n. sp. is the first record of the genus outside India. Taxonomic positions of the new species are discussed along with ecological information. One-hundred and six nonmarine ostracod species are now reported from Texas. However, ongoing studies suggest that actual species richness is much higher.

摘要

2015 年至 2017 年间，在美国德克萨斯州的地表溪流潜流区的 111 个样本中，于 30 个地点采集到了 58 个介形类群。其中，有 6 个新物种（Bradleycypris foresteri n. sp.、Bradleystrandesia macula n. sp.、Pseudocandona lordi n. sp.、Indocandona rusti n. sp.、stenocypris sancari n. sp.和 Cyclocypris dalyana n. sp.）是基于甲壳和软体制成部分而描述的。此外，还有 17 个物种和 2 个属（Vestalenula 和 Indocandona）被列为德克萨斯州的新记录，而 Indocandona rusti n. sp.则是该属在印度以外地区的首次记录。新物种的分类地位与生态信息一起进行了讨论。目前，德克萨斯州已报告了 106 种非海洋介形类动物。然而，正在进行的研究表明，实际的物种丰富度要高得多。
