Abstract
Batellopsis paula gen. et sp. nov., a new hexactinellid-associated alpheid shrimp, is described based on a single specimen collected at a depth of 477-503 m north of Île des Pins, New Caledonia. Batellopsis gen. nov. is part of a clade of four genera all containing hexactinellid-associated species, for which a molecular phylogeny is presented. The evolution of several morphological characters, including orbital teeth, a bulgefossa system on the fingers of the first pereiopod chela, and groups of microserrulate setae on the second pereiopod chela, is discussed in light of phylogenetic results.
根据在新喀里多尼亚Île des Pins以北477-503米深处采集到的一个标本，描述了一种新的与hexactinellid相关的长脚虾（Batellopsis paula gen.Batellopsis gen. nov.是一个由四个属组成的支系的一部分，这四个属都含有与hexactinellid相关的物种，本文介绍了该支系的分子系统发生。根据系统发生学的结果，讨论了几个形态特征的演变，包括眼眶齿、第一围足螯指上的隆起苔系统和第二围足螯指上的微锯齿刚毛群。
