Aruba, Bonaire, and Curaçao (ABC Islands) are located at the southern margin of the Caribbean Plate, just north of South America. Little is known of the arachnid fauna of these islands, and the only work on spiders was published over a century ago. Here we provide a list of arachnids opportunistically collected from the islands, including Klein Bonaire and Klein Curaçao, over approximately 2 months. More than 750 specimens from 4 arachnid orders, (Amblypygi, Pseudoscorpiones, Scorpiones, Araneae) were collected and identified. We recovered 1 species of amblypygid, 2 species of pseudoscorpions, 1 species of scorpion, and 76 species of spiders. Additionally, we compared species diversity between urban and natural areas. The number of species is relatively low given the proximity to South America, but this likely reflects that collecting only took place for a short time and was opportunistic as opposed to systematic. Nevertheless, we found 25 new records and >20 likely undescribed species for the islands, providing insights into the spider fauna of northern South America and indicating that additional surveys of the area are warranted.

阿鲁巴，博内尔岛和库拉索岛的蛛形纲（Arachnida）

阿鲁巴岛（Aruba），博内尔岛（Bonaire）和库拉索岛（Curaçao）（ABC群岛）位于加勒比板块的南缘，就在南美北部。人们对这些岛屿的蛛网动物几乎一无所知，关于蜘蛛的唯一著作发表于一个多世纪前。在这里，我们提供了大约2个月内从包括Klein Bonaire和KleinCuraçao在内的群岛随机收集的蜘蛛网的清单。收集并鉴定了来自4个蜘蛛纲目（Amblypygi，Pseudoscorpiones，Scorpiones，Araneae）的750多个标本。我们回收了1种弱视虫，2种假蝎，1种蝎和76种蜘蛛。此外，我们比较了城市和自然地区之间的物种多样性。鉴于靠近南美，物种数量相对较少，但这可能反映了收集仅发生了很短的时间，并且是机会主义的，而不是系统的。尽管如此，我们发现了25个新记录和20多个可能未描述的岛屿物种，从而深入了解了南美北部的蜘蛛动物区系，并表明有必要对该地区进行额外的调查。
