A new species of Oxybelis is described from Isla de Roatán, Honduras. It differs from all species of Oxybelis in its tan to golden yellow coloration, in having a higher number of subcaudals as well as in other details of color and scutellation. The new species is closely related to O. fulgidus and is thought to be derived from a fulgidus-like ancestor (i.e., is the sister species to fulgidus) that has been isolated in the area of its present range probably since the very late Pliocene. The presence of a yellow population of Oxybelis on Isla de Roatán, Honduras, has long been known (Keiser 1969). The status of this insular population has remained uncertain pending the acquisition of additional material (Keiser 1969, Wilson and Meyer 1985). We recently visited Isla de Roatán a number of times and obtained a large series of additional specimens. After examining this new material, and the previously known specimens from this island, we believe that this population represents an undescribed taxon, which should be known as.
一种新的食蜗蛇属物种在洪都拉斯的罗阿坦岛被描述。它与食蜗蛇属的所有物种不同，体呈棕褐色至金黄色，尾下鳞数量更多，以及在颜色和鳞片排列的其他细节上也有差异。这个新物种与华丽食蜗蛇关系密切，被认为源自一个类似华丽食蜗蛇的祖先（即华丽食蜗蛇的姐妹物种），可能自上新世晚期以来就一直隔离在其当前分布区域。洪都拉斯罗阿坦岛上存在黄色食蜗蛇种群，这早已为人所知（凯泽，1969年）。在获取更多标本之前，这个岛屿种群的分类地位一直不确定（凯泽，1969年；威尔逊和迈耶，1985年）。我们最近多次访问罗阿坦岛，并获得了大量额外标本。在检查了这些新标本以及该岛先前已知的标本后，我们认为这个种群代表了一个未被描述的分类单元，应称为……
