【摘要】 阿莱鼓虾属Arete Stimpson曾被多个研究者作为Athanas Leach角鼓虾属的异名处理(Banner and Banner,1960 , 1973 ;Chace, 1988 ;Miya and Miyake, 1968) ,作者认为Kemp(1915)描述Athanus polymorphus多形角鼓虾出现的第2胸足腕节4节为形态变异,第2胸足腕节分节情况完全可以将两属分开,阿莱鼓虾属应该做有效属处理。文中记述了中国海分布的3个种:A.borradailei,A.dorsalis,A.indicus,其中A.borradailei为中国海首次报道。文中详细描述A.borradailei,并提供了世界阿莱鼓虾属种的检索表。所有研究标本保存在中国科学院海洋研究所。更多还原

【Abstract】 The present paper is the fifth part of the systematic studies of the Alpheid fauna(Crustacea,Decapoda)of the China seas.The genus Arete is treated here by the present authors as a valid genus,but not as a junior synonym of Athanas Leach(A.H.Banner and Banner,D.M.,1960),because that the 4-segmented carpus of the 2nd pereiopod found by Kemp(1915:295)in Athanas polymorphus is only a variation among individuals within the species.The main differences between the two genera are the carpus article number of second leg and the carpus shape of first leg.A total of 3 species of the genus Arete Stimpson,1860,are reported in the paper,of which A.borradailei Coutière is recorded for the first time from the China seas.Descriptions of new recorded species and key to known species in the world are given.All examined specimens are deposited in the Institute of Oceanology,Chinese Academy of Sciences.更多还原
