摘要
在小安的列斯群岛瓜德罗普岛La dsamsiade以东111-162米处采集的雄性完整型中，发现了一种非常重要的新种Synalpheopsis gen. nov.，即Synalpheopsis laureae sp. nov.。Synalpheus gen. 11 .特别地结合了两个属的特征，alpheus coutire, 1897和Synalpheus Spence Bate, 1888;然而，它可能更接近前一属。新属的特征是中等发育的眶盖，发育良好的喙部和眶齿，无关节瓣的第6多棱体，第3上唇的尖端有刺状刚毛的冠，双侧边缘有两颗强壮的牙齿，手指切割边缘缺乏咬合机制，鳃柄无乳突分支和刚毛分支。
On a Remarkable New Genus and Species of Alpheid Shrimps (Malacostraca: Decapoda: Caridea) from the Tropical Western Atlantic
Synalpheopsis gen. nov. is established for a remarkable new alpheid species, Synalpheopsis laureae sp. nov., presently known only from the male holotype collected at 111–162 m east of La Désirade, Guadeloupe, Lesser Antilles. Synalpheopsis gen. nov. peculiarly combines features of two genera, Alpheopsis Coutière, 1897 and Synalpheus Spence Bate, 1888; however, it is presumably closer to the former genus. The new genus is characterised by the moderately developed orbital hoods, well-developed rostrum and orbital teeth, sixth pleonite without articulated flap, tip of the third maxilliped with crown of spiniform setae, chelipeds with two strong teeth on distolateral margin and lacking snapping mechanism on finger cutting edges, and gill formula without mastigobranchs and setobranchs.
期刊介绍：
