Abstract


A new species of the genus Scutiger from Bhutan is described on the basis of two specimens without precise locality. The new species is placed in the Scutiger glandulatus group. Within this group, it differs from Scutiger jiulongensis by the large size of the spines on its breast, of Scutiger glandulatus by its important webbing and by its flattened warts on the back, and from Scutiger tuberculatus, which seems to be its closest known relative, by its smaller size and the absence of spines under the arms. A tentative phylogenetic analysis of a representative set of 17 species of Megophryidae, based on 54 external morphological characters, suggests that, in the genus Scutiger, the subgenus Scutiger is paraphyletic relative to the subgenus Aelurophryne. As these data are only preliminary, we suggest to keep using these two subgenera for the time being. We provide new diagnoses for these two subgenera, with lists of included species-groups and species.
