摘要:
在我国南海海域大型底栖生物进行分类和多样性研究中,发现我国长眼寄居蟹属2个新记录种,紫斑长眼寄居蟹(Paguristes gonagrus)和条纹长眼寄居蟹(Paguristes runyanae),并对其进行描述。紫斑长眼寄居蟹采集自海南岛,主要特征为:螯足和步足密布刚毛,第一触角柄未达到角膜基部,螯足腕节、掌节背面刺和突起密集而发达,螯足和第二、三步足长节末端有紫色色斑;条纹长眼寄居蟹采集于西沙群岛,主要特征为:右螯足略大于左螯足,第一触角柄短,长度仅为眼柄长度的1/2,螯足和第二、三步足背腹面均有黄色条纹。

Abstract:
Two species of genus Paguristes, Paguristes gonagrusand Paguristes runyanae, are recorded and described for the first time from the South China Sea. Paguristes gonagrusspecimen collected from Hannan Island is characterized by dense covering of long soft setae. Antennular peduncle far falls short of the distal corneal margins. Tubercles and spines are developed on the dactylar dorsal surface and chelipeds and ambulatory legs with violet spot distally. Paguristesrunyanaespecimen collected from Xisha Islands is characterized by a slightly larger right cheliped, short antennular peduncle, half-length of ocular peduncles, dorsa-ventral sides of chelipeds and ambulatory legs with stripes of yellow.
Key words:  marine biology  Paguristes  Paguristes gonagrus  Paguristes runyanae  new record species
