摘要
在巴西东北部发现了3个新种,首次记录了该属在南半球的分布。所检查的材料是在“avalia o da Biota Bentônica e Planctônica da Bacia Potiguar e ceear”项目中使用Mini Box cover收集的,该项目位于里约热内卢Grande do Norte州的Potiguar盆地,深度为283-998米。双翅龙的特征是:头部有背龙骨;天线2花梗条1弱剑形;颚足目动物2掌,由一个产生脊椎的大挖掘定义;外板1后腹角作为一短钝的裂片;而外板3面有一排斜刚毛,后腹角为大棘。根据以下特征可诊断为:触角2花序梗条1剑形;颚足目1手掌由u形的挖掘定义;髋7后缘具小圆齿;外板3后腹侧角为棘;尾足2外支有近根尖甲。最后,长趾棘猴具有以下诊断特征:头部下侧钝突;天线2条1不均匀;颚足目动物1-2掌,由弯曲的凹陷界定;准足目6趾足目比原足目长;外板3后腹圆形。文中还对该属进行了讨论,并给出了世界种的鉴定关键字。
First record of the genus Harpinia Boeck, 1876 (Amphipoda: Phoxocephalidae: Harpiniinae) from the southern hemisphere, with description of three new species
ABSTRACT Three new species of Harpinia are described from north-eastern Brazil, documenting the first record of the genus from the southern hemisphere. The material examined was collected using a Mini Box Corer within the project ‘Avaliação da Biota Bentônica e Planctônica da Bacia Potiguar e Ceará’ in Potiguar Basin, Rio Grande do Norte state, from depths ranging from 283–998 m. Harpinia bidens sp. nov. is characterized by the following: head with dorsal keel; antenna 2 peduncle article 1 weakly ensiform; gnathopod 2 palm defined by a large excavation producing a spine; epimeral plate 1 posteroventral corner as a short blunt lobe; and epimeral plate 3 with an oblique facial row of setae, posteroventral corner as a large spine. Harpinia kingae sp. nov. can be diagnosed by the following: antenna 2 peduncle article 1 ensiform; gnathopod 1 palm defined by a u-shaped excavation; coxa 7 posterior margin crenulate; epimeral plate 3 posteroventral corner as a spine; and uropod 2 outer ramus with subapical nail. Finally, H. longidactyla sp. nov. has the following diagnostic characters: head with lower lateral blunt projection; antenna 2 article 1 not ensiform; gnathopods 1–2 palm defined by a sinuous excavation; pereopod 6 dactylus longer than propodus; and epimeral plate 3 posteroventrally rounded. Also, a discussion about the genus and an identification key to world species of Harpinia are provided.
期刊介绍:
Marine Biology Research (MBRJ) provides a worldwide forum for key information, ideas and discussion on all areas of marine biology and biological oceanography. Founded in 2005 as a merger of two Scandinavian journals, Sarsia and Ophelia, MBRJ is based today at the Institute of Marine Research, Bergen, Norway. The Journal’s scope encompasses basic and applied research from all oceans and marine habitats and on all marine organisms, the main criterium for acceptance being quality.
