A history of the description of the 50 valid species of is given, beginning with the first species described in 1860. To help differentiate the various species, a tabular and a polychotomous key are provided. The species in the keys are arranged using nine characters or character sets that are believed to be of value at the species level. New characters or new significance given to previously described characters used in our keys include: 1) the nature of the dorsolateral edge of the basal scale, being ridged or not, 2) the thickness of the body wall scales, and 3) the arrangement of the coenenchymal scales (imbricate or mosaic), their thickness (thin or massive), and their outer surface ornamentation (ridged or not). All characters used in the keys are illustrated.
本文给出了自1860年首次描述该物种以来，50个有效物种的描述历史。为帮助区分不同物种，提供了一个表格和一个多歧分类检索表。检索表中的物种按照九个被认为在物种层面具有价值的特征或特征集进行排列。我们的检索表中使用的新特征或赋予先前描述特征的新意义包括：1）基部鳞片背外侧边缘的性质，是否有脊；2）体壁鳞片的厚度；3）共肉鳞片的排列方式（覆瓦状或镶嵌状）、厚度（薄或厚）以及其外表面纹饰（是否有脊）。检索表中使用的所有特征均有图示。
