摘　　要：2022年9月作者在浙江宁波象山港海域采集到短小拟五角蟹(Paranursia abbreviata),由此短小拟五角蟹的地理分布记录从中国的海南岛、广东、香港地区和福建扩展到东海北部,即浙江北部的象山港。本文对其形态特征进行了详细的描述,并讨论了其与历史记载的外形差异。由于象山港冬季水温较低,推测短小拟五角蟹在象山港的出现可能是台湾暖流携带幼体定居导致的偶然现象。In September 2022,Paranursia abbreviata(Bell,1855)was collected from Xiangshan Bay,Ningbo,Zhejiang Province,extending the geographical distribution record of Paranursia abbreviata from Hainan Island,Guangdong,Hong Kong Region,and Fujian to the northern East China Sea and Xiangshan Bay in northern Zhejiang Province.In this study,the morphological characteristics of Paranursia abbreviata are described in detail,in addition to the morphological differences between the present specimen and the previous material.In view of the low winter water temperature in Xiangshan Bay,the occurrence of Paranursia abbreviata may be an occasional event caused by larval settlement carried by the Taiwan Warm Current.
