The genus Lepidochitona is one of the most diverse in the Southern Caribbean. In order to describe this new species, twenty specimens of L. bullocki sp. nov. were collected by hand on the rocky coast, from 0.25 to 1.5m depth, and a shore distance of 1 to 5m, between the Northern section of Rodadero beach and Puerto Luz, in Santa Marta, Colombia. The specimens were small, with maximum observed size of 7.3mm. This is the fourth species of the genus Lepidochitona described for the Caribbean. The previously known species were L. liozonis (Dall & Simpson 1901), L. rosea (Kaas 1972) and L. rufoi (Garcia-Ríos 2010). L. bullocki differs from L. liozonis and L. rosea in having a rough tegmentum and color. It differs from L. rufoi in having longer and numerous hyaline spicules, bigger size and broader central radula tooth. Lepidochitona bullocki is the only Caribbean species of the genus frequently located on the illuminated side of rocks in the shallow sublitoral zone.
鳞石鳖属是加勒比海南部最多样化的属之一。为了描述这个新物种，在哥伦比亚圣玛尔塔罗达德罗海滩北段和卢兹港之间的岩石海岸，从0.25米至1.5米深、离岸距离1至5米处，手工采集了20个布氏鳞石鳖新物种标本。这些标本很小，观察到的最大尺寸为7.3毫米。这是为加勒比地区描述的鳞石鳖属的第四个物种。此前已知的物种有光滑鳞石鳖（Dall & Simpson，1901年）、玫瑰鳞石鳖（Kaas，1972年）和鲁氏鳞石鳖（Garcia-Ríos，2010年）。布氏鳞石鳖与光滑鳞石鳖和玫瑰鳞石鳖的区别在于其有粗糙的背甲和颜色。它与鲁氏鳞石鳖的区别在于有更长且数量更多的透明针状棘、更大的尺寸和更宽的中央齿舌齿。布氏鳞石鳖是该属在加勒比地区唯一经常位于浅亚潮带岩石光照一侧的物种。
