oa Annals of the Natal Museum - Advertisement call structure and morphology of Breviceps mossambicus Peters and B. poweri Parker (Anura: Microhylidae) from northern Mozambique

Volume 38, Issue 1
  • ISSN : 0304-0798



An analysis of advertisement calls indicates that a population of B. mossambicus from the type locality, Mozambique Island, and two populations from the adjacent mainland, are conspecific. B. mossambicus calls differ from those of B. adspersus from Pietersburg, South Africa, with regard to call duration, number of pulses and the grouping of calls within the call boul. These differences support the recognition of adspersus and mossambicus as separate species.The calls of B. poweri from Nampula are unpulsed and are grouped within the call bout to a greater extent than those of mossambicus and adspersus. Certain morphological characters are examined and their diagnostic value is discussed.
