Checklist of Fishes from Madagascar Reef, Campeche Bank, México

This study presents the first list of fish species from Madagascar Reef, Campeche Bank, Gulf of México. Field surveys and literature review identified 54 species belonging to 8 orders, 30 families and 43 genera, comprising both conspicuous and cryptic fishes. Species richness was lower at this reef site compared to reefs in the Mexican Caribbean, Veracruz or Tuxpan, but was similar to other reefs in the same region. Species composition was a mixture of species present in all the reef systems of the Mexican Atlantic. Hypoplectrus ecosur was recorded here for the first time in the Gulf of Mexico, Mycteroperca microlepis, Equetus lanceolatus and Chaetodipterus faber were new records for the reefs of the Campeche Bank, Elacatinus xanthiprora was recorded for the second time in Mexico and expanded its known distribution westwards from Alacranes Reef and Sanopus reticulatus, endemic of the Yucatan state, was recorded here for the first time on a reef.

本研究首次揭示了马达加斯加珊瑚礁、坎佩切银行、墨西哥湾的鱼类物种名录。通过野外调查和文献综述，共鉴定出54种鱼类，隶属于8个目、30个科和43个属，包括显眼与隐蔽的鱼类。与墨西哥加勒比海的珊瑚礁、韦拉克鲁斯或图克斯潘的珊瑚礁相比，该礁区的物种丰富度较低，但与其他该区域珊瑚礁的物种丰富度相似。物种组成是墨西哥大西洋所有珊瑚礁系统中现有物种的混合。首次在墨西哥湾记录到 Hypoplectrus ecosur，Mycteroperca microlepis、Equetus lanceolatus 和 Chaetodipterus faber 是坎佩切银行珊瑚礁的新记录，Elacatinus xanthiprora 在墨西哥的记录次数增至两次，并扩展了其已知分布范围至阿拉坎斯礁以西，Sanopus reticulatus，一种特有于尤卡坦州的鱼类，首次在该礁区被记录。
