DistributionNE Madagascar (Bemanevika Lakes region)

Type locality: Madagascar, Mahajanga Province, Bealanana
Fivondronana, Bemanevika Lakes Forest, Matsaborimena, 14°09.859’S, 48°35.240’E, 1650 m elevation.  
TypesHolotype: AMNH 152386 (RAX 6222), male 
DiagnosisDiagnosis: A Calumma chameleon from Mada- gascar that differs from all congeners by the combination of a single ossified rostral append- age projecting upward in the male, and which does not project anterior to the mouth, 17–18 gular spines; a pair of large occipital lobes that are dorsally united to each other by more than 3 mm in adult, and the number of dorsal crest tubercles between the occipital lobes and point above the insertion point of hind limbs (male 36, female 52). Calumma hafahafa is most similar to C. peltierorum and C. malthe, but can be distin- guished by the form of the ossified rostral appendage in the male (projects upward and not anterior to the mouth vs. projects forward and anterior to the mouth); and the number of dorsal crest tubercles between the occipital lobes and point above the insertion point of hind limbs (males: 36 vs. .44; females 52 vs. .60). [from RAXWORTHY & NUSSBAUM 2006]. 
EtymologyNamed after the Malagasy word “hafahafa”, meaning bizarre or strange, in reference to the unique upturned rostral appendages.
