在巴拿马西部和哥斯达黎加的科迪勒拉山脉，已知有几个分布广泛的新热带属Bolitoglossa（Plethodontidae）的大型（成年标准长度，43-134毫米）黑色蝾螈种群。这些种群至少包括7个物种，包括最近描述的两个（B. anthracina，B. copia），一个很久以前描述的，仍然知之甚少（B。nigrescens），以及本文描述为新的三种。长期公认的，援助范围B。robusta的特征是尾基周围有一个苍白的色素环，上颌骨和犁骨齿数的独特组合，可能与其他四个分类群同域出现。在头部和身体的形式，成人的大小，颅骨，上颌和犁骨齿数的差异分离所有公认的类群彼此。这些结果证实并确实增加了哥斯达黎加和巴拿马的科迪勒拉塔拉曼加-巴鲁地区的蝾螈物种的高度多样性，这种多样性现在可以与热带其他任何地方的物种相媲美。
Several populations of large (adult standard length, 43-134 mm) black salamanders of the widespread neotropical genus Bolitoglossa (Plethodontidae) are known from the cordilleras of western Panama and Costa Rica. These populations constitute at least seven species, including two recently described (B. anthracina, B. copia), one described long ago that remains poorly known (B. nigrescens), and three described herein as new. The long recognized, Aide-ranging B. robusta, which is distinguished by a pale, pigmented ring around the tail base and a unique combination of maxillary and vomerine tooth counts, may occur sympatrically with four of the other taxa. Differences in head and body form, adult size, cranial osteology, and maxillary and vomerine tooth counts separate all recognized taxa from one another. These results confirm and indeed increase the exceedingly high diversity of salamander species known from the Cordillera Talamanca-Baru of Costa Rica and Panama, diversity that now rivals that found anywhere else in the tropics.
