We evaluate the monophyly and phylogenetic relationships of the Pristimantis leptolophus species group and describe its external morphology, osteology, and some myological characteristics. We also compare the P. leptolophus species group to other related species groups. The P. leptolophus group is not monophyletic due to the inclusion of P. acatallelus, formerly believed to be part of the P. devillei group. The revised P. leptolophus group is composed of nine named species and six unnamed species. Based on our results, we recognize a new species group, the P. boulengeri species group, composed of eight species, many of which were previously assigned to the P. lacrimosus species group.
我们评估了细棱短头蟾物种组的单系性和系统发育关系，并描述了其外部形态、骨骼学和一些肌学特征。我们还将细棱短头蟾物种组与其他相关物种组进行了比较。由于包含了曾被认为是德氏短头蟾组一部分的无距短头蟾，细棱短头蟾组并非单系的。修订后的细棱短头蟾组由9个命名物种和6个未命名物种组成。基于我们的结果，我们识别出一个新的物种组，即布氏短头蟾物种组，由8个物种组成，其中许多物种之前被归入泪腺短头蟾物种组。
