Abstract

Seven species of Orbiniidae are described from the Pacific coast of Costa Rica including two new species. Leodamas hamatus n. sp., a commonly occurring species on the coast of Pacific Costa Rica, is described from 11‒18 m in the Gulf of Nicoya and Bahia Culebra. This species is unusual in that the neuropodial uncini differ morphologically from anterior to posterior in the thorax. Scoloplos cryptospinigerus n. sp. is described from 18-22 m in the Gulf of Nicoya and has only a few short, toothed spines amidst numerous capillary setae in most of the thoracic neuropodia. This arrangement of thoracic neurosetae is unusual and has been seen only in one other described species of Scoloplos from Australia.

摘要

从哥斯达黎加太平洋海岸描述了7种蛰龙介科动物，包括两个新物种。哈氏利奥达马斯虫（Leodamas hamatus）新物种，是哥斯达黎加太平洋海岸常见的物种，从尼科亚湾和库莱布拉湾11至18米深处采集到该物种。该物种的不同寻常之处在于，胸部神经足的小钩在形态上从前向后有所不同。隐棘斯克洛普斯虫（Scoloplos cryptospinigerus）新物种，从尼科亚湾18至22米深处采集到，在大多数胸部神经足中，众多的毛细管状刚毛中仅有少数短的、带齿的刺。这种胸部神经刚毛的排列方式很不寻常，仅在澳大利亚描述的另一种斯克洛普斯虫中见过。
