摘要

在得克萨斯州中部的4个石灰岩岩溶泉中，描述了一种新的Stygobromus bakeri sp.nov；约翰·诺克斯泉（科马尔县）、雅各布井（海斯县）、摩门泉（特拉维斯县）和萨拉多泉（贝尔县）。该物种属于Stygobromus的主要西部近北hubbsi物种群，与该群中其他物种的不同之处在于颚足类1，在界定角后有4至5排刚毛，潜足类6和7，基部广泛扩张，有明显的distosterior裂片，稍远侧的花序梗刚毛。讨论了栖息地、同域地下水物种和保护问题。

Stygobromus bakeri, a new species of groundwater amphipod (Amphipoda, Crangonyctidae) associated with the Trinity and Edwards aquifers of central Texas, USA

A new stygobitic groundwater amphipod species, Stygobromus bakeri sp. nov., is described from 4 central Texas limestone karst springs; John Knox Spring (Comal County), Jacob’s Well (Hays County), Mormon Spring (Travis County) and Salado Springs (Bell County). This species belongs to the predominately western Nearctic hubbsi species group of Stygobromus and differs from other species in the group by gnathopod 1 with row of 4 to 5 setae posterior to the defining angle, pereopods 6 and 7 with broadly expanded bases and distinct distoposterior lobes, gnathopods 1 and 2 with 2 rows of 3 singly inserted setae on the inner palm, and uropod 3 with single, slightly distal peduncular seta. Habitat, sympatric groundwater species, and conservation issues are discussed.

期刊介绍： Subterranean Biology is an international journal published by Pensoft on behalf of the International Society for Subterranean Biology [SIBIOS-ISSB] for the publication of original and significant contributions on all aspects of subterranean life. The Journal will consider original scientific papers dealing with any aspect of subterranean ecosystems and their components focusing on biology, ecology, evolution and conservation. Reviews and Commentaries: The journal welcomes review articles on aspects of subterranean biology. They should be submitted in the same way as research articles but use a simple layout with no more than three levels of headings. Commentaries on previous matter published in the journal may be also considered. Both reviews and commentaries will be reviewed. Book Reviews: Reviews of books, symposia volumes and conferences pertinent to the journal are welcome. The journal publishes electronic versions of the articles when these are ready to publish, without delays that might be caused by completion of an issue. These electronic versions are not "pre-prints" but final and immutable (Version of Record), hence available for the purposes of biological nomenclature. The date indicated on the electronic version is to be considered the actual publication date.
