Colombian brachiopod faunas have not been studied extensively. Only three brachiopod species have been reported from the Colombian Caribbean Sea so far, namely Argyrotheca barrettiana (Davidson, 1866), Terebratulina latifrons Dall, 1920, and the cosmopolitan Platidia anomioides (Scacchi & Philippi, 1844). In this work, brachiopods collected from deep-water environments (90-250 m) off the San Bernardo Archipelago, collected during the MARCORAL cruise, are examined. The studied material consists of four species, two of which are new records for Colombia: Terebratulina cailleti Crosse, 1865 and Tichosina plicata Cooper, 1977. The genus Tichosina belongs to the family Terebratulidae and comprises twenty extant species occurring across the Caribbean. Based on a revision of published descriptions and illustrations, we synonymize Tichosina bullisi Cooper, 1977 and Tichosina dubia Cooper, 1977 with Tichosina plicata Cooper, 1977. Remarkably, apart from reports from southern Guiana, T. plicata is restricted to the margins of the Caribbean plate.
哥伦比亚的腕足动物群尚未得到广泛研究。到目前为止，哥伦比亚加勒比海仅报道过三种腕足动物，即巴氏银孔贝（Argyrotheca barrettiana，戴维森，1866年）、宽额穿孔贝（Terebratulina latifrons，多尔，1920年），以及广布种奇异扁孔贝（Platidia anomioides，斯卡奇和菲利皮，1844年）。在这项研究中，我们对在“MARCORAL”航次期间采集的、来自圣贝尔纳多群岛附近深水环境（90 - 250米）的腕足动物进行了检查。研究材料包括四个物种，其中两个是哥伦比亚的新记录种：卡氏穿孔贝（Terebratulina cailleti，克罗斯，1865年）和褶纹蒂氏贝（Tichosina plicata，库珀，1977年）。蒂氏贝属属于穿孔贝科，包含20个现存物种，分布于加勒比地区。基于对已发表描述和插图的修订，我们将1977年库珀命名的布氏蒂氏贝（Tichosina bullisi）和1977年库珀命名的可疑蒂氏贝（Tichosina dubia）同褶纹蒂氏贝（Tichosina plicata，库珀，1977年）进行了同义处理。值得注意的是，除了圭亚那南部的报道外，褶纹蒂氏贝仅限于加勒比板块边缘。
