Rana Tepuyana

Diagnosis: This species can be diagnosed as a member of the Hypsiboas benitezi (see Faivovich et al. 2005), based on the following combination of characters: (1) body size (30.0-36.0 mm SVL in males, 34.5-47.7 mm SVL in females); (2) dorsal skin smooth or slightly shagreened, ventral skin smooth or slightly granular; (3) snout rounded to truncated when viewed from above, rounded when viewed from the side, with distinct, rounded canthi; (4) indistinct tympanum, sometimes barely visible; (5) elliptical and moderately large choanae; (6) vomerine teeth are distinct and number 7-16 on each dentigerous process, with the processes either straight and converging toward the anterior of the mouth or arc-shaped; (7) vocal slits reaching from tongue midlength to the posterior of the jaw; (8) Finger I is the same length as Finger II; (9) no lateral fringes present on fingers; (10) ulnar tubercles are lacking or very weakly developed; (11) no heel calcars; (12) both metatarsal tubercles present but only the inner one is well-developed; the inner metatarsal tubercle is oval-shaped while the outer metatarsal tubercle is tiny and nearly indistinct; (13) in life, coloration is bright yellow dorsally with brown markings, or brown with gray markings, or darker brown with yellow dorsolateral stripes, along with reddish-orange fingers, toes, and webbing; (14) in preservative, coloration is pale yellow to gray or brown, with markings such as dark transverse bars, a reticulum, or dorsolateral stripes (Barrio-Amoros and Brewer-Carias 2008).Similar species in the Guayanan region: H. benitezi is larger, has a ridge of distinct ulnar tubercles (none or indistinct in H. tepuianus), and a different advertisement call (; H. lemai has a yellow dorsum but can change to brown during the day, Finger I shorter than Finger II (vs. approximately equal in H. tepuianus), and basal webbing between all fingers (vs. webbing absent between Fingers I and II but basal between all other fingers in H. tepuianus). H. rhythmicus has creamy-colored fingers, toes and webbing (vs. reddish-orange in H. tepuianus), a golden iris (vs. gray to bronze in H. tepuianus), small digital discs (vs. large in H. tepuianus), a different advertisement call with a single note at a higher dominant frequency of 3260-3450 Hz (vs. two to five notes at a lower dominant frequency of 2500 Hz for H. tepuianus), and calls from the undersides of leaves (vs. on top of leaves and sticks for H. tepuianus). H. jimenenezi and H. sibleszi are mainly green and sometimes brown in life (vs. yellow or brown for H. tepuianus) (Barrio-Amoros and Brewer-Carias 2008). Description: Adult males measure 30.0-36.0 mm SVL. Adult females measure 34.5-47.7 mm SVL. Large head with a broad upper eyelid. Dorsal skin is mostly smooth, but weakly shagreened. Ventral skin is smooth, but weakly granular. Distinct canthus rostralis with a slightly concave loreal region. Indistinct tympanum with a weakly defined supratympanic fold. Distinct dentigerous processes of the vomers with about 7-16 teeth on each process. Round wide tongue. Forearms moderately robust. Fingers may or may not have lateral fringes. Long fingers with round expanded terminal discs. Indistinct supernumerary tubercles and palmar tubercles. Fingers have basal webbing and toes are extensively webbed. Both genders have an enlarged pollex (more so in males) with a hidden prepollical spine. No axillary membrane. Hind limbs are long, with adpressed heels reaching beyond the snout in mature males but only to the eyes in females. Toes have large round subarticular tubercles, but lack supernumerary tubercles. The inner metatarsal tubercle is flat and ovoid, while the outer metatarsal tubercle may be absent, nearly indistinct, or round. Males have white tubercles on both sides of the vent opening (Barrio-Amoros and Brewer-Carias 2008). Although Faivovich et al. (2006) describe this species as having a mental gland, Barrio-Amoros and Brewer-Carias (2008) were not able to conclusively identify one; they mention seeing a whitish quadrangular area on the chin but note that this is present in both male specimens and the single female specimen.In life, the dorsum is bright yellow with brown specks, brown with gray specks or dark brown with yellow dorsolateral stripes. Fingers and toes are reddish-orange and have reddish-orange webbing (Barrio-Amoros and Brewer-Carias 2008). In preservative, the dorsal surface is a light yellow to gray with a few shades of brown or the surface can be reddish brown with with darker brown specks. Transverse dark brown bars and dirty white dorsolateral stripes are present (Barrio-Amoros and Brewer-Carias 2008).Its name comes from the table mountains (tepuis) of Southern Venezuela where the species was found. This species consists of populations from east of the Maigualida-Parima Mountains in Venezuela (and extending into Brazil) that were formerly known as Hypsiboas benitezi or the earlier name Hyla benitezi (Barrio-Amoros and Brewer-Carias 2008).

Venezuelan Guayana and extreme northern Brazil. In Venezuela, known localities include: Auyan-tepui (Barrio-Amoros and Brewer-Carias 2008), the upper Río Ambutuir (Gorzula and Señaris 1999), Guaiquinima (Donnelly and Myers 1991), Sarisariñama-tepui (Barrio-Amoros and Brewer-Carias 2008), Jauatepui (Gorzula and Señaris 1999; Señaris and Ayarzagüena 2002), Quebrada de Jaspe (Gorzula and Señaris 1999), and extreme northern Brazil (Vila Pacaraima; Heyer 1994, as Hyla benitezi). The type locality is on the southern slope of Sarisariñama-tepui, Locality VI, Estado Bolívar, Venezuela at 420 m asl. Over the entire range this species is found at elevations from 420-1800 m ASL (Barrio-Amoros and Brewer-Carias 2008).

Males called while sitting on branches, leaves, and bushes that were about 0.5-1.5 m above the water (Barrio-Amoros and Brewer-Carias 2008). Calls from Sarisariñama populations consist of three to five notes with a dominant frequency of 2500 Hz and a fundamental frequency of 1700 Hz, plus two harmonics at 4900 and 7500 Hz (Barrio-Amoros and Brewer-Carias 2008). One female was found in the spray zone of a waterfall (Barrio-Amoros and Brewer-Carias 2008). Females were also found at night sitting on rocks near small waterfalls, about 1-2 m above the water (Donnelly and Myers 1991, as Hyla benitezi).

The tepui tree frog (Boana tepuiana) is a frog in the family Hylidae, endemic to Brazil and Venezuela. Scientists have seen it between 420 and 1800 meters above sea level.

The adult male frog measures 30.0-36.0 mm in snout-vent length and the adult female frog 34.5-47.7 mm. The skin on the frog's dorsum is not granular, but the skin of the ventrum may be. The skin on the dorsum is bright yellow with some brown marks, brown with gray marks, or dark brown with yellow stripes. The toes and webbing between the toes are red-orange in color.

The frog's tongue is wide and round, and it has vomerine teeth in its jaw.

This frog's scientific name, tepuiana, refers to the Tepui Mountains in Venezuela, which are part of its range.
