2002年11月和12月，使用桁拖网和中层拖网，对苏禄海的深海超底桡足类进行了动物区系调查。本文描述了原始哲水蚤科的两个新属和四个新种。一新属Metacalanalis的特征介于Metacalanus Cleve，1901和Pilarella Alvarez，1985之间。另一个新属，Protoparamisophria，与Paramisophria Scott，1897密切相关，但在女性生殖系统和附属器中表现出更多的近形状态。本文记述了拟剑水蚤属Paraugaptiloides Ohtsuka，Boxshall and Roe，1994和Sarsarietellus Campaner，1984两新种，分别为该属的第二和第三种。这一发现增强了这些稀有属的有效性，并揭示了苏禄海的地质历史和其中的Arietellidae的进化。
A faunistic survey of the deep-sea hyperbenthic copepods in the Sulu Sea, which has a deep basin and is connected via shallow straits with the Pacific and the South China Sea, was carried out in November and December 2002, using beam trawls and a mid-water trawl. Two new genera and four new species of the primitive calanoid family Arietellidae are described. A new genus Metacalanalis shows intermediate characteristics between those of Metacalanus Cleve, 1901 and Pilarella Alvarez, 1985. Another new genus, Protoparamisophria, is closely related to Paramisophria Scott, 1897, but exhibits more plesiomorphic states in the female genital system and appendages. Two new species of the genera Paraugaptiloides Ohtsuka, Boxshall and Roe, 1994 and Sarsarietellus Campaner, 1984 are the second and the third species, respectively, for these genera. This discovery enhances the validity of these rare genera, and sheds light on the geological history of the Sulu Sea and the evolution of the Arietellidae within it.
