OREOBATES SAXATILIS ( DUELLMAN, 1990) View in CoL
Ischnocnema saxatilis Duellman, 1990
Oreobates saxatilis View in CoL – Caramaschi & Canedo (2006) ( Fig. 3N)
Ischnocnema saxatilis Duellman, 1990: 1 . Holotype: KU 212556. Type locality: ‘ Ponga de Shilcayo GoogleMaps , about 4 km NNW of Tarapoto, 470 m (6°31′S, 76°53′W), Provincia de San Martín, Departamento de San Martín, Peru’ ( Fig. 4 View Figure 4 ).
Diagnosis: A large Oreobates (SVL of adults, 44.5– 50.0 mm) characterized as follows: (1) skin of dorsum granular, with round keratinized granules and small, sparse, low, flat warts, only some of them slightly enlarged; warts on flanks slightly larger than those of dorsum; venter smooth; posterior surfaces of limbs smooth, groin areolate; discoidal fold present; no dorsolateral folds; large postrictal glands; (2) tympanic membrane and annulus distinct, both with length of about two thirds of the eye length; supratympanic fold weak, short; (3) head large, wider than long; snout short, round in dorsal and lateral views; canthus rostralis slightly convex or sinuous in dorsal view, round in profile; (4) cranial crests absent; upper eyelid covered by small warts and granules; (5) dentigerous process of vomers large, transverse, situated posteromedial to choanae; (6) vocal slits and nuptial pads condition unknown; (7) hands with long and slender fingers, first finger longer than second; subarticular tubercles large, prominent, round to conical; supernumerary tubercles large, conical, smaller than subarticular tubercles; tips of fingers III and IV round, not enlarged, lacking circumferential grooves and ungual flap; lateral fringes and keels on fingers absent; (8) single round, low, ulnar tubercle; (9) no tubercles on heel or tarsus; (10) inner metatarsal tubercle ovate, prominent; outer metatarsal tubercle smaller, round, prominent; supernumerary tubercles conspicuous, conical; (11) toes long and slender (foot length 50% of SVL), lateral fringes absent, webbing absent; tips of toes rounded, not enlarged, with ungual flap not indented; (12) condition of axillary, sacral, and inguinal glands unknown; (13) dorsal coloration greyish brown with darker brown markings; throat and chest cream with dense brown mottling; belly immaculate.
Among the large Oreobates , O. saxatilis is most similar to O. quixensis , but differs by being smaller and having more scattered warts, and by having an immaculate belly. From all small Oreobates it differs by its larger size and by having keratinized granules on dorsum and non-enlarged fingertips.
Remarks: The original description and diagnosis are accurate ( Duellman, 1990). However, Duellman (1990) mentioned the presence of narrow lateral fringes on fingers and toes, a character that we did not find in the specimens examined. Its advertisement call is unknown; nothing is known about the natural history of this species.
Distribution: Known only from the type locality ( Fig. 4 View Figure 4 ).
