| 摘 要： | 长期以来,中国海倒颚蟹属仅记录一种,即渤、黄、东海底栖动物常见种异足倒颚蟹AsthenognathusinaequipesStimpson,1858。作者对中国科学院海洋生物标本馆收藏的采自中国海的全部倒颚蟹属标本进行系统研究后共发现除该种外还有以下2种,为中国海的新记录:宽身倒颚蟹AsthenognathusgallardoiSer埁neandSoh,1976和六角倒颚蟹AsthenognathushexagonumRath-bun,1909,均采自南海北部。异足倒颚蟹为中国北方和东部海域常见种,但未见于南海。六角倒颚蟹与异足倒颚蟹形态上较相似。两者差异在于六角倒颚蟹头胸甲六角形,后缘约与额-眼眶缘等宽,背面有2对凹陷,后侧缘有2条颗粒脊,而异足倒颚蟹头胸甲后缘约为额-眼眶缘宽的1.5倍,背面仅有浅横沟。宽身倒颚蟹与其他两种形态差异较大,头胸甲宽约为长的1.9倍。

| Abstract: | This paper reports the species of Genus Asthenognathus Stimpson from China seas based on the crab collections deposited in the Marine Biological Museum of Chinese Academy of Sciences, Qingdao. In addition to Asthenognathus inaequipes Stimpson, 1858, commonly found in northern and eastem China seas. Asthenognathus hexagonum Rathbun, 1909 and Asthenognathus gallardoi Serène and Soh, 1976, are recorded here for the first time from China. Diagnoses of the species are given and comparisons between the two closely related species are made. |
