Didynamipus sjostedti

COMMENTS. — The distribution of this poorly known species has been recently revised by Gonwouo et al. (2013), who also provided insights on its natural history, stating that its reproductive mode is direct development. Our record from southern Bioko expands the distribution range of this species southwards. No phylogeographic studies have been performed including this monotypic taxon. The synonym Atelophryne minutus Boulenger, 1906, described from Bioko, represents an available name if future work confirms the specific distinctiveness of insular populations. SPECIMENS EXAMINED. — Nine specimens. From Belebu to Ureca, 3 ° 24 ʹ 25.81 ” N, 8 ° 33 ʹ 3.23 ” E, 19 November 2003 (MNCN 48947 – 48954, 46872).

DISTRIBUTION. — This species occurs both in continental Africa, where it extends from Cameroon (see Gonwouo et al. 2013) to Nigeria (Onadeko et al. 2010), and on Bioko, where it was reported from Basilé by Boulenger (1906 a). Since then, no additional records have been published for this country. We found an additional population from south Bioko province, located in the surroundings of Caldera de Luba (Map 10 B).

TYPE LOCALITY. — “ Kamerun ”, Cameroon.
