GBIF Taxonomic Backbone & Wikipedia Registry Profile

Description of holotype. Adult male in good state of preservation (Fig. 9). A small piece of muscle tissue from right thigh removed for molecular analysis. Ventral skin cut open and bladder removed for parasite examination. SVL 28.0 mm. For full morphometric measurements see Table 1. Body relatively slender; head slightly longer than wide, wider than body; snout rounded in dorsal, ventral, and lateral views; nostrils much nearer to tip of snout than to eye, slightly protuberant and pointed anterolaterally; canthus rostralis distinct, straight; loreal region straight; tympanum distinct, relatively small, its diameter 70 % of eye diameter; distinct supratympanic fold; tongue ovoid, strongly bifid posteriorly; posterior tongue extensions slightly serrated; vomerine teeth as one weakly expressed rounded aggregation posterolateral of each choana; choanae small, rounded. Forelimbs slender; subarticular tubercles distinct and single; central metacarpal tubercle large and rounded, outer metacarpal tubercle smaller and oval; a small but indistinct prepollex (which could also be considered as an inner metacarpal tubercle) at base of first finger. Fingers without webbing; relative finger length I <II <IV <III; finger discs distinctly enlarged; nuptial pads absent. Outer toe and finger discs darker than inner toe and finger discs. Hind limbs long and slender; when adpressed along body, the tibiotarsal articulation reaches beyond the eye; lateral metatarsalia connected by tissue; inner metatarsal tubercle distinct, larger than outer; outer metatarsal tubercle distinct; webbing formula of the foot 1 (traces), 2 i (traces), 2 e (1), 3 i (2), 3 e (1), 4 i (2.75), 4 e (3), 5 (1.25); relative toe length I <II <III = V <IV. Skin dorsally smooth; ventral skin as far as recognizable smooth on throat, chest, slightly granular on belly. Femoral glands recognizable from external view but not very distinct, also in life (Fig. 12) not very prominent and of same color as surrounding shank, possibly because the specimen was collected outside of the reproductive season. Glands consisting of many small gland granules in a relatively diffuse field covering most of thigh ventrally, thus of type 1 as defined by Glaw et al. (2000). After eleven years in preservative (70 % EtOH; Fig. 9), dorsal background coloration grayish brown with two prominent blackish dorsolateral discontinuous bands consisting of densely arranged blotches and extending posteriorly from eye orbits to hips. Rostral stripe dark brownish. Dorsally, from between orbits a dense field of brown blotches, running over most of dorsum and becoming more scattered on posterior dorsum. Interrupted and indistinct whitish middorsal line. Forelimbs with irregular and partially interrupted dark, brownish bands and spots extending from shoulders to fingers. Outer finger discs darkish brown. Ventrally, throat and forelimbs largely unpigmented (yellowish-brownish in preservative), chest with some fine dark brown dotting, belly more pigmented with dense pattern of brown dots that leave out some larger unpigmented markings, and the hindlimbs dark largely brown. Dorsal surface of thighs and shanks dark reddishbrown with indistinct broad dark blotches and interrupted bands. Like finger discs, some outer toe discs dark reddish brown, of noticeably different color than adjacent tissue. Based on photographs of the holotype specimen (Fig. 12), body coloration in life was pinkish brown. Dorsally and on both forelimbs and hindlimbs, with a chocolate brown pattern, consisting of irregular-sized blotches and spots. Also, supratympanic fold and rostral stripe chocolate brown. Dorsally, from an imaginary line between the orbits to the axilla with a dense field of brown blotches. A yellowish interrupted and indistinct middorsal line. Ventrally, background color pinkish-whitish, but chest, throat and the anterior part of belly bright white. Posteriorly and laterally belly semi-transparent. Ventrolaterally, small white spots in anterior part, larger bright yellow spots posteriorly. First finger and toe intensely yellow. Numerous femoral gland granules visible, but not highlighted in color. Iris (whitish in preservative) copper metallic in life.
Biology & Conservation

Ecologically, the conservation status of Guibemantis razoky is officially designated as Unknown. Current field registries estimate a global population composed of an unquantified number of individuals, making habitat preservation critical to maintaining their wild populations.

It is typically endemic to forest, mountain, showing great physiological synergy with its surroundings. In terms of dietary preferences, it relies primarily on a diet of flying insects, forest spiders, and crawling invertebrates. It exhibits specialized adaptations centered around a nocturnal activity pattern, optimizing its energy conservation and interactions within its native ecosystem. The species has a typical natural lifespan of approximately 6 years, allowing it to adapt and mature through structured generational cycles.

Ongoing biological monitoring and ecological advocacy emphasize the importance of protecting this species. The stability of its food chain and the prevention of fragmentation in its primary range are vital for the continued survival of Guibemantis razoky.
