|Types||Holotype: MHNG 2645.001 (field tag TZ 414), male, 21 October 2000. Collected by J. Mariaux & S. Loader. Paratype: PEM R16271, ZFMK 87393 (ex-MHNG 2645.003), male|
|Diagnosis||Diagnosis. Chamaeleonidae, Rhampholeon (Rhinodigitum). With the characters of the subgenus. A small chameleon with SVL 47–57 mm (maximum TL 82 mm) and a tail 25–30% of TL. Adults are unmistakable due to their large discoid and vertically flattened rostral process (up to 5 × 3 mm) projecting forward off the rostrum (Figs 6-7), spinous supra-orbital and other cranial projections, prominent casque, exaggerated dorsal crest and numerous spines on the body, limbs |
and tail. No axillary or inguinal pits. Claws bicuspid. Parietal peritoneum unpigmented.
Differential diagnosis. Among the pygmy chameleons, only Rh. spinosus presents a similar rostral process. However, Rh. spinosus has a more rounded rostral proc-
ess, numerous spiny tubercles on the gular region, a slender overall appearance, and a significantly longer tail (up to more than 40% of TL); furthermore it is not
sympatric with Rh. acuminatus. Although several other species, like Rh. uluguruensis and related taxa, also have rather conspicuous naso-rostral processes, these are more cylindrical and much smaller. Furthermore these species do not show the characteristic body spines seen in Rh. acuminatus, thus making confusion unlikely.
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
|Etymology||From Latin acuminare (to sharpen), in reference to the numerous sharp spines found on the head and body.|
