Unlike all other Cardioglossa, in life the coloration of the new species is typically brownish red, with no dorsal markings, but with a pair of thin, golden white lines that extend posteriorly from the tip of the rostrum and terminate just above and behind the tympanum. This new species is morphologically similar to C. oreas, another high-altitude species endemic to the Cameroonian mountains: both have small tympana and lack the hypertrophied third manual digit typical of males of other Cardioglossa. The tadpole of the new species is similar to that of C. occidentalis, the only other Cardioglossa for which the tadpole is fully described, but differs in having a broad anterolaterally projecting supraoral labium, lacking ventral pigmentation, and having a relatively longer spiracular tube. Several features of tadpole morphology are convergent with the unusual fossorial tadpole of the microhylid Otophryne and suggest a similar convergence in ecology. Principal components analysis of morphometric data, followed by discriminant function analysis, was used to explore patterns of morphological similarity within Cardioglossa. These analyses provide support for five species groups: (1) C. aureoli (distinct from other Cardioglossa); (2) C. escalerae, C. gratiosa and C. nigromaculata; (3) C. gracilis, C. melanogaster and C. schioetzi; (4) C. sp. nov. and C. oreas; and (5) C. cyaneospila, C. pulchra, C. venusta and C. trifasciata. The inclusion of C. cyaneospila in the last group supports previous suggestions of past biotic connections between the Albertine Rift mountains and those of the Cameroon Volcanic Line. The description of this new species further emphasizes Mt Manengouba as a centre of anuran endemism within the Cameroonian mountains and reaffirms the importance of this ecoregion within sub-Saharan Africa.

A clade endemic to the mountains of western Cameroon and eastern Nigeria, part of the geologic rift zone termed the Cameroon Volcanic Line, supports the view that montane regions have acted as centres of speciation. Bioko Island (Equatorial Guinea), located 32 km off the coast of Cameroon, is populated by three different lowland Phrynobatrachus species from the mainland. Two of these species, Phrynobatrachus auritus and Phrynobatrachus cornutus reach submontane elevations on Bioko Island (up to 1200-1300 m) but are present only at lowland elevations on mainland Cameroon. A new miniature species of puddle frog of the genus Phrynobatrachus restricted to Mt Oku in the Republic of Cameroon is diagnosed on the basis of morphological characters and molecular data. Unlike all other miniature Phrynobatrachus (snout-vent length &lt; 20 mm), males of this species have unique ventral coloration characterized by a black throat, dark brown to black pectoral and abdominal regions, and a light or white area on the proximal hind limbs. Minute spines cover the venter in males, often appearing as white asperities. The description of this new species supports the significance of this montane ecoregion as a biodiversity hotspot for anurans.
