| Diagnosis | DIAGNOSIS: Chamaeleo chapini seems to be most closely related to Chamaeleo adolfifriderici Sternfeld (1912), a small species known from few specimens, all taken in the eastern portion of the Congo (Districts of Kibali-Ituri, Nord Kivu, Sud Kivu, and Rwanda). Chamaeleo chapini (fig. 1), however, lacks the parietal and dorsal crests, as well as the conical scales on the lateral crests, that are characteristic of C. adolfifriderici. The tail of C. chapini is proportionately somewhat shorter, for it comprises slightly less than half of the over-all length, in contrast to 0.53 to 0.57 reported by Schmidt (1919) for C. adolfifriderici (de Witte 1964). |
| Comment | Distribution: For a map with localities in Equatorial Guinea see SÁNCHEZ-VIALAS et al. 2022. Abundance: Rare. This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024. |
| Etymology | Named after Dr. James Paul Chapin (1889-1964), an American ornithologist and co-leader ofthe Lang-Chapin expedition, which made the first comprehensive biological survey of the Belgian Congo (1909-1915). |
