The ant fauna in natural and rural areas of Jamaica has received substantial interest in the past. However, no recent works have focused primarily on the ants of urban and suburban areas. In this study, we assessed the species richness and origin of ants in urban and suburban areas of St. Andrew, Jamaica. Ant specimens were hand-collected within a 30 m radius area during a 15 minute search conducted at 27 sample sites during 39 sampling events. A total of 31 ant species were collected, representing a mixture of 18 native (58.1%) and 13 introduced (41.9%) species. Among the 18 species native to the Caribbean region, three (9.7%) are endemic to Jamaica, namely Camponotus hannani, Camponotus fugax, and Cephalotes jamaicensis. Sixteen tramp species (species with a worldwide distribution) represented 51.6% of the ant community, including Brachymyrmex patagonicus, Nylanderia steinheili, Paratrechina longicornis, Tapinoma melanocephalum, and Trichomyrmex destructor. Brachymyrmex patagonicus, Solenopsis geminata, and P. longicornis were most prevalent, being respectively found at 92.6%, 85.2%, and 81.5% of the sampled sites. Brachymyrmex obscurior, Camponotus fugax, Camponotus sexguttatus, Crematogaster steinheili, and Pheidole subarmata were among the least prevalent, each found at only one site. This publication presents the first published records of Solenopsis globularia and Monomorium pharaonis in Jamaica, with short descriptions of their habitats. The urban and suburban ant community of St. Andrew presents a relatively high species richness.

牙买加圣安德鲁城市和郊区蚂蚁（膜翅目：蚁科）的物种丰富度和起源

牙买加自然和农村地区的蚂蚁动物群过去引起了人们的极大兴趣。然而，最近的作品并没有主要关注城市和郊区的蚂蚁。在这项研究中，我们评估了牙买加圣安德鲁城市和郊区蚂蚁的物种丰富度和起源。在 39 个采样事件中，在 27 个采样点进行了 15 分钟的搜索，在 30 m 半径区域内手工采集了蚂蚁标本。总共收集了 31 种蚂蚁，其中包括 18 种本地蚂蚁（58.1%）和 13 种引进蚂蚁（41.9%）。在加勒比地区原生的 18 种物种中，有 3 种（9.7%）是牙买加特有的，即汉纳弓背蚁 (Camponotus hannani)、福加克斯弓背蚁 (Camponotus fugax) 和牙买加弓背蚁 (Cephalotes jamaicensis)。16种流浪物种（分布于世界各地的物种）占蚂蚁群落的51.6%，包括Brachyrmex patagonicus、Nylanderia steinheili、Paratrechina longicornis、Tapinoma melanocephalum和Trichomyrmex destructor。Brachymyrmex patagonicus、Solenopsis geminata 和 P. longicornis 最为常见，分别占采样点的 92.6%、85.2% 和 81.5%。Brachymyrmex obscurior、Camponotus fugax、Camponotus sexguttatus、Crematogaster steinheili 和 Pheidole subarmata 是最不常见的，每种都只在一个地点发现。本出版物介绍了牙买加首次发表的红火蚁 (Solenopsis globularia) 和 Monomorium pharaonis 记录，并对其栖息地进行了简短描述。圣安德鲁城市和郊区的蚂蚁群落呈现出较高的物种丰富度。
