Abstract

Abstract Verrill described Astropecten comptus and Astropecten nitidus 100 years ago. The species have been accepted and have been reported off the east coast of North America and South America, the Caribbean, and the Gulf of Mexico. The validity of the species has never been questioned. Because we had difficulty distinguishing A. comptus from A. articulatus and A. nitidus from A. cingulatus, we examined basic morphological diagnostic characteristics in astropectens of the neotype of A. articulatus, the holotype of A. cingulatus, the paralectotype of A. comptus, the holotype of A. nitidus, the holotype of A. nitidus forcipatus, and many specimens that had been identified as A. cingulatus, A. nitidus, A. articulatus, A. comptus, and other Astropecten species of the West Atlantic Region. We conclude that A. comptus is a synonym of A. articulatus and A. nitidus is a synonym of A. cingulatus. This has implications for current concepts of zoogeography and biodiversity in the region and for the phylogeny of astropectinids.

Astrobecten nitidus Verrill的同义词，1915年与Astrobectn cingulatus Sladen的同义词（1883年），Astrobectten comptus Verrill与Astrobicten articulatus的同义词

Verrill在100年前描述了Astropecten comptus和Astropectten nitidus。该物种已被接受，并在北美洲和南美洲东海岸、加勒比海和墨西哥湾被报道。该物种的有效性从未受到质疑。由于我们很难区分A.comptus和A.articulatus以及A.nitidus和A.cingulatus，我们在天文学家中检查了A.articultus的新型、A.cingulats的正模、A.comptuss的副外模、A.nitidu的正模和A.nitidusforciptus的正模的基本形态学诊断特征，以及许多已被鉴定为西大西洋地区的A.cingulatus、A.nitidus、A.articulatus、A.comptus和其他Astrobecten物种的标本。我们得出结论，A.comptus是A.articulatus的同义词，A.nitidus是A.cingulatus的同义词。这对该地区目前的动物地理学和生物多样性概念以及类星体的系统发育都有影响。
