The family Phrynidae has been mainly recorded from America, including the Antilles, and Heterophrynus is one of its genera endemic of South America and is mainly associated with Amazonian ecosystems. Currently, the genus has 16 valid species, but many original descriptions are ambiguous or incomplete. The more complete work about this genus only includes seven of the currently valid species, and in some cases, some characters useful for the species identification, were not described. This situation hampers the species recognition and the comparison among species to propose diagnosis accurate. Using characters from the male and female genitalia to improve the diagnosis, we present complementary descriptions for four species of Heterophrynus and describe two new species. We present details of morphologic variation, compare the pedipalp spines among the species, present actualized distributions, and for first time, we present a complete illustration of the male genital of eight species using SEM pictures.
蟾足蟾科主要分布于美洲，包括安的列斯群岛，而异蟾属是南美洲特有的属之一，主要与亚马逊生态系统相关。目前，该属有16个有效物种，但许多原始描述含糊不清或不完整。关于该属更完整的研究仅涵盖了目前有效物种中的7种，而且在某些情况下，一些对物种鉴定有用的特征并未被描述。这种情况妨碍了物种识别以及物种间的比较，从而难以提出准确的诊断。利用雄性和雌性生殖器的特征来改进诊断，我们给出了异蟾属4个物种的补充描述，并描述了2个新物种。我们展示了形态变异的细节，比较了各物种间的触肢刺，给出了最新分布，并且首次使用扫描电子显微镜图片完整展示了8个物种的雄性生殖器。
