A rather large frog (Males to 37 mm, females to 43 mm) from highlands in eastern R. D. Congo. Dorsum warty, digital discs dilated, webbing reduced. No vocal sac and no vocal sac openings. Dorsum chocolate brown to almost black with numerous small orange or golden spots. Hidden parts of limbs yellow to orange, ventrum pink, mauve or bluish, whitish in juveniles. Iris brown.
In view of the lack of vocal apparatus and the reduced hearing apparatus it is reasonable to assume that the males are mute. Nothing is known of amplexus, eggs, deposition site or tadpoles.
By day, Callixalus is found in the broken stalks of bamboo from 2–4 m above ground in bamboo forests of the Itombwe plateau. On the Kabobo Mts. where bamboo is scarce it is found hiding during the day between the bark and the moss which often covers the trunks of trees.
