Bokermannohyla langei (Bokermann 1965)

Know only from the type locality in Serra do Mar, Marumbí, Paraná State, Brazil.

Description of holotype Adult male (total length 66.4 mm). Head broader (23.4 mm) than long; snout not projecting, rounded in lateral profile; canthus well defined; loreal region concave; tympanum very small (2. 2 mm in diameter nearly circular, indistinct and partially hidden under the supratympanic fold) little more than one-fourth the diameter of eye, and separated from the posterior border of eye by a distance nearly twice its own diameter. Supratympanic fold well developed. Eye projected antero-laterally, its transverse diameter (8.2 mm) larger than the distance from eye to nostril (5.2 mm). Nostrils placed under the canthus rostralis and directed slightly backward. Interorbital distance, nearly the same as the horizontal diameter of eye. Internal nares nearly circular; vomerine teeth in two separate patches, between and posterior to the internal nares. Tongue large and flat, nearly circular, slightly free and notched behind, occupying nearly the entire floor of the mouth. Vocal sac subgular; slits under the margin of the tongue. Fingers webbed at base, with well developed terminal discs larger than tympanum. First finger with a well developed bifid prepollex. Subarticular and supernumerary tubercles well developed; carpal tubercles poorly differentiated. Forearm greatly thickened, almost as in certain Leptodactylus. Upper arm with a humeral crest and a humeral hook similar to the condition in Bokermannohyla martinsi. Hind limbs normal, heels barely overlap when legs are folded at right angles to axis of body; tibio-tarsal articulation reaches to eye. Toes three-fourths webbed; the web reaches the disc of toes III and V and the penultimate phalange of toe IV. Discs of toes slightly smaller than those of fingers; subarticular and supernumerary tubercles well developed; only one tarsal tubercle, on the base of first toe; tarsalfold poorly developed. Skin of dorsum nearly smooth; ventrally the skin is smooth in the gular region and becomes more granular posteriorly; abdomen and ventral surface of thigh very granular. The coloration is faded in this preserved specimen. The dorsum is brown; the sides of the head and body are lighter. The concealed surfaces of the thighs and ventral surface of the body are very light brown. The dorsal surfaces of the fore arms, thighs, tibiae, and tarsi have indistinct light cross bars. Notes on the allotype: The specimen is an adult female with ripe abdominal eggs. In size it is a little smaller than the holotype (length 60.0 mm; head width 22.0 mm; diameter of eye 8.0 mm; eye to nostril 5. 0 mm). The dorsal markings are more evident. A large dark brown blotch exists in the middle of the dorsum which extends from the interorbital space to the sacral region. The groin has a few light yellowish markings. The forearms, thighs, tibiae, and tarsi are distinctly barred with light yellowish. The tympanum (diameter 2.0 mm) is more evident and a little smaller than in the holotype.

Bokermannohyla langei és una espècie de granota de la família dels hílids. Només es coneix que visqui a la seva localitat tipus al sud-est del Brasil, a Marumbi, a l'Estat de Paranà, a una altitud d'uns 500 metres (encara que possiblement habiti a qualsevol). No se sap res de l'espècie des que tres individus van ser capturats l'any 1953, tot i els esforços que s'han fet per retrobar-la.

Viu en boscos humits i està associada a rierols. Es desconeixen els seus hàbits de reproducció, encara que probablement ho fan a l'aigua.

Bokermannohyla langei is a species of frog in the family Hylidae. It is endemic to Brazil, known only from Paraná. It is known from three specimens collected in 1953 and searches since 1986 have not found this frog. Its natural habitats are subtropical or tropical moist lowland forests, rivers, freshwater marshes, and intermittent freshwater marshes. It may be threatened by touristic activities but is protected by Parque Estadual Pico do Marumbi.
