|Diagnosis||Diagnosis: Uroplatus fivehy sp. nov. is assigned to the Uroplatus ebenaui species group based on its relatively small size, leaf-like, laterally-compressed body shape, short tail, and triangular head with supraocular spines. The following unique combination of characters characterizes the new species: (1) short (TAL/SVL 0.21–0.41) and slender (TAW/SVL 0.06–0.13) tail, (2) oral mucosa without black pigment, and (3) relatively smooth (not spiny) appearance in males. Additionally, it is distinguished by high genetic pairwise-distances > 10% in DNA sequences of the mitochondrial 16S gene from all other nominal species of Uroplatus.|
By its overall leaf-like appearance, the species can easily be distinguished from all members of the U. fimbriatus species group, from U. lineatus, and from the phenetic U. alluaudi species group. Within the U. ebenaui species group, U. fivehy sp. nov. can be distinguished from U. finaritra and U. malama by smaller body size (SVL 60.8–72.4 mm versus 77.5–95.3 mm); from U. malama, U. phantasticus, U. finiavana and U. finaritra by shorter tail (TAL/SVL 0.21–0.41 versus 0.48–0.76); from U. fangorn, U. ebenaui, U. fetsy, and U. kelirambo by its unpigmented oral mucosa (pale pinkish all over versus black or deep red pigment present); from U. kelirambo by more expanded tail edges (versus strongly spear-shaped; TAW/SVL 0.06–0.13 versus 0.04–0.05 in U. kelirambo). U. fivehy sp. nov. is morphologically most similar to U. fiera and to U. fotsivava, which however concordantly differ in mitochondrial and nuclear DNA sequences and are not its immediate relatives based on molecular phylogenetic analysis; it differs from U. fotsivava by a generally longer and wider tail, although the values do overlap (TAL/SVL 0.21–0.41 versus 0.15–0.32; TAW/SVL 0.06–0.13 versus 0.05–0.10), and from U. fiera possibly in a slightly larger ratio TAL/TAW (0.22–0.37 versus 0.19–0.21).
Variation. As described for U. fangorn above, there is a substantial color variation (Figs 6–7), and sexual dimorphism in the edges of the tail. The color of the eye varies from beige/gray to dark brown and reddish-brown. Dorsal color can be uniform beige to reddish-brown with or without white lichen-like markings. Two sharply delimited vertebral black patches on the anterior and posterior part of the dorsum are present in several individuals. Relative tail length and tail width are characterized by substantial variability among individuals (Fig. 4).
