Data from: A new mesophotic goby, Palatogobius incendius (Teleostei: Gobiidae), and the first record of invasive lionfish preying on undescribed biodiversity

A new species of deep-reef fish in the goby genus Palatogobius is described from recent submersible collections off Curaçao and Dominica. Video footage of schools of this species reveal predation by the invasive Indo-Pacific lionfish (Pterois spp.), the first record of undescribed fauna potentially being eaten by lionfish outside of its native range. We present molecular phylogenetic data for all valid species of Palatogobius and related genera, as well as a taxonomic key to the species of Palatogobius and a generic key to Palatogobius and related genera in the western Atlantic. Lastly, we discuss ecological and behavioral aspects of some deep-reef fishes in light of potential threats from invasive lionfish.基于库拉索岛与多米尼加岛周边海域近年的深潜器采集标本，本研究记述了鰕虎鱼类腭齿鰕虎鱼属（Palatogobius）1个新的深礁鱼类物种。该物种集群活动的影像资料显示，其遭到入侵性印度洋-太平洋蓑鲉（Pterois spp.）的捕食——这是首个在蓑鲉原生分布范围以外，未被正式描述的动物类群可能被蓑鲉捕食的记录。本研究提供了腭齿鰕虎鱼属及相关属所有有效物种的分子系统发育数据，同时构建了西大西洋区域腭齿鰕虎鱼属物种的分类检索表，以及腭齿鰕虎鱼属与相关属的属级分类检索表。最后，本研究结合入侵性蓑鲉带来的潜在威胁，探讨了部分深礁鱼类的生态与行为特征。
