The Philippine endemic genus Bullimus is currently considered to include three species, one each from the Late Pleistocene islands of Greater Mindanao, Greater Luzon, and Camiguin. We describe a fourth species, Bullimus carletoni, new species, from the Caramoan Peninsula in southern Luzon based on analyses of molecular and craniodental data. Molecular data suggest that Bullimus colonized Luzon from the southern Philippines and began diversifying on Luzon by ca. 232 kya. This species is associated with partially disturbed forest habitat over limestone and ophiolitic soils, where it is active primarily on the ground at night. Recognition of this species raises the number of endemic mammals on the Bicol Peninsula of southern Luzon to six, emphasizing its importance as a center of endemism.

菲律宾特有属Bullimus目前被认为包括三个物种，每个物种来自大棉兰老岛、大吕宋岛和甘米银岛的更新世晚期岛屿。我们根据对分子和颅牙数据的分析，描述了来自吕宋岛南部 Caramoan 半岛的第四个物种Bullimus carletoni，新物种。分子数据表明Bullimus大约从菲律宾南部殖民吕宋岛，并开始在吕宋岛多样化。第232话 该物种与石灰岩和蛇绿土壤上部分受干扰的森林栖息地有关，在那里它主要在夜间活跃在地面上。对该物种的认可使吕宋岛南部比科尔半岛的地方性哺乳动物数量增加到 6 种，强调了其作为地方性中心的重要性。
