Fig. 2: Right lower jaw of D. africanus from Fernando Poo (= Bioko): female ZFMK 5885. phot. C. Esch (ZFMK). The two ZFMK specimens are a couple, the female being from Parador and the male being from Bonyoma. With 29 resp. 27 mm SVL they are bigger than the dimensions recorded for this species (see Perret 1966: 369). They both have enlarged mandibular "teeth" followed by smaller ones (Fig. 1 and 2), they lack femoral glands, but the male has very distinct metacarpal glands (Fig. 3). The terminal phalangae are neither trapezoid nor T-shaped. The two SMF specimens are both males and agree with the ZFMK male in the above mentioned characters. Therefore, the frogs fit the definition of Dimorphognathus and not of Phrynodon, both by their size and their diagnostic characters. Whereas the three specimens from the Parador above Musola (800 m: ZFMK 5885 and SMF 64988-989) agree well also in their outer.
