Comments: Ptychadena ansorgii is a species known from the western and extreme northeastern regions of Angola ( Marques et al. 2018 ). The species was not cited by Ferreira in any of his publications regarding Newton’s expedition to Angola ( Ferreira 1904 , 1906 ) and, therefore, constitutes an additional record of this species for the country, even if without associated collecting data.
