A new species of the Hyloscirtus larinopygion group from Nudo de los Pastos, Nariño department, Colombia is described. Hyloscirtus tigrinus sp. nov. can be distinguished easily from similar species by the presence of a fleshy and prominent calcar tubercle and by its distinctive color pattern. Some remarks on throat and ventral coloration in Hyloscirtus caucanus, H. larinopygion, H. lindae and H. tigrinus are presented. The throat coloration is highly variable and cannot be used to diagnose any of these species.

The description of the species Callulina kreffti was based on specimens collected in the East Usambara Mountains of Tanzania. Successive collecting has shown this species to be widely distributed through the Eastern Arc Mountains. Advertisement calls from populations in the type locality of Callulina kreffti were compared with calls from populations in the West Usambara Mountains. Analysis of the calls suggested that these two populations of Callulina represent two separate taxa. Subsequent morphological and molecular investigations indicated that these two populations are distinct. Herein, we describe a new Callulina species on the basis of call, morphology and molecular sequences.
