Diagnostic Description

provided by IABIN
Description of holotype Body robust, bufoniform. Head as wide as long, slightly narrower than body; head length 38% of snout-vent length, snout short with length almost equal to eye diameter, rounded in lateral and dorsal views; nostrils protuberant, directed anterolaterally; canthus rostralis not distinct; loreal region weakly concave; lips nearly sigmoid; eye slightly protruding in dorsal and lateral views, eye diameter 26% of head length; tympanum absent; vocal sac not expanded externally; vocal slits present; tongue longer than wide, posterior 1/2 not adherent to floor of mouth; choanae relatively small and round; vomerine odonthophores absent. Upper arm and forearm relatively slender, upper arm approximately as long as forearm; fingers IÂ?III robust, short and distinct; finger IV reduced; tip of fingers I and II slightly rounded, tip of finger III pointed; relative lengths of fingers IV , I , II , III; subarticular tubercles and inner and outer metacarpal tubercles absent. Legs relatively short, thigh robust; thigh length 37% of snout-vent length, tibia length 97% of thigh length; toe I externally absent, toes IIÂ?III short and distinct; toe IV robust and distinct, toe V very reduced only visible as a slight bulge; relative lengths of toes V , II , III , IV; subarticular tubercles and inner metatarsal tubercles absent; outer metatarsal tubercle distinct, large, and ovoid. Skin on top of the head and central part of the back body smooth and with no dermal coossification; skin on dorso-lateral surfaces of body, flanks, and dorsal surface of thighs granular; skin on venter and ventral surfaces of the legs smooth; skin on ventrolateral surfaces of body and area around the cloacal opening granular. Coloration of holotype in life: Dorsum orange; dorso-lateral skin covered with very weak dark orange tubercles, especially on flanks. Head with an approximately circular, central post-orbital spot and one inconspicuous spot above each eye. Head markings, dorso-vertebral stripe, and leg articulations pale bright yellow with very small olive gray dots; central head marking more greenish than the others. Lateral areas of body, flanks, and thighs with small dark brown spots. Limbs dark orange. Throat dark orange and belly orange with brownish coalescent spots and small dots, and with a short, ventral pale bright yellow stripe. Coloration of holotype in preservative:General color pale cream; lateral spots dark brown; coalescent spots and small dots on belly pale greyish. Measurements of holotype: snout-vent length 13.1; head length 5.0; head width 5.3; internarinal distance 1.3; eye diameter 1.3; interorbital distance 2.6; eye-nostril distance 0.7; thigh length 4.8; tibia length 4.7. Variation in the type series Color in life on dorsum orange varying from spectrum orange to chrome orange; central head marking usually more greenish than other head marks; lateral small glands dark orange or slightly brownish; lateral areas of body with different amounts of small dark brown spots; belly of some specimens with a short, ventral pale bright yellow stripe.

Brachycephalus pombali

provided by wikipedia EN

Brachycephalus pombali is a species of frogs in the family Brachycephalidae. It is endemic to Brazil and only known from its type locality, "Morro dos Padres, Pico da Igreja", in the Serra do Mar in Guaratuba, Paraná state. The type locality is at about 1,300 m (4,300 ft) above sea level.[1][2][3]

Etymology

The specific name pombali honors José Perez Pombal, Jr., a Brazilian herpetologist who has worked with the genus Brachycephalus.[2][4]

Description

As all brachycephalids, Brachycephalus pombali are small: adult males measure 12.6–13.9 mm (0.50–0.55 in) and females 14.6–15.3 mm (0.57–0.60 in) in snout–vent length; this miniaturization is associated with loss of phalanges in hands and feet. The body is robust and toad-like. There is no tympanum. The general color is orange, lateral surfaces have small dark brown spots, and belly has brownish coalescent spots and small dots. The skin on top of the head and central part of the back body is smooth and without dermal co-ossification, whereas the skin on dorso-lateral surfaces of body, flanks, and dorsal surface of thighs is granular.[2]

Habitat and conservation

Brachycephalus pombali inhabit the leaf litter in the Atlantic Rainforest. They are active by day. Adult males are exposed on the litter when calling.[1][2] There are no known threats to this species, but it is only known from a single location.[1][3]
