Two new species of the genus Cephalophoxoides Gurjanova, 1977 are described. The material examined was collected during the Mini Biological Trawl (MBT) project, off Brazil's southeastern coast on the states of Rio de Janeiro and São Paulo, at depths ranging from 34 to 75 meters. Cephalophoxoides fortisetus sp. nov. resembles C. homilis (Barnard, 1960) in some general aspects of mandible, propodus of gnathopods 1-2, basis of pereopod 5 and rami of uropod 1. However, it can be distinguished by the latter species mainly by distinct characters on the maxilliped, gnathopod 1, uropod 2 and uropod 3. Also, the new species presents 1 short and 2 long stout setae on the lobes of telson as a notable character. Cephalophoxoides obtusimanus sp. nov. can be distinguished from its congeners by presenting gnathopod 1 with an obtuse and weakly chelate palm as an exclusive character of the genus. An identification key for all species of Cephalophoxoides of the world is provided.
描述了头颚钩虾属（Cephalophoxoides Gurjanova，1977）的两个新物种。所检查的材料是在“小型生物拖网（MBT）”项目期间收集的，位于巴西东南海岸里约热内卢州和圣保罗州，深度在34至75米之间。新种强刚毛头颚钩虾（Cephalophoxoides fortisetus sp. nov.）在下颚、第1 - 2步足的腕节、第5步足的基部以及第1尾足的分支等一些总体特征上与同属的霍氏头颚钩虾（C. homilis (Barnard, 1960)）相似。然而，它与后一种的区别主要在于颚足、第1步足、第2尾足和第3尾足上的明显特征。此外，新物种在尾节的叶上有1根短刚毛和2根长的粗壮刚毛，这是一个显著特征。钝掌头颚钩虾（Cephalophoxoides obtusimanus sp. nov.）与其同属物种的区别在于，其第1步足具有一个钝圆且弱螯合的掌部，这是该属独有的特征。提供了世界上头颚钩虾属所有物种的鉴定检索表。
