NEW DENDROBATID FROG FROM THE VENEZUELAN ANDES

A new species of dendrobatid frog has been described in the most recent issue of the journal Herpetotropicos.

Source: HERPETOTROPICOS Vol. 7(1-2):55-74



Abstract: In this paper we discuss the rediscovery of the types of Colostethus meridensis (= Aromobates meridensis), during long time believed to be lost, give a redescription of the holotype, and redescribe its sympatran Aromobates mayorgai, a taxon previously known only from the type specimens. In addition, we describe a new species from the mountains of Piñango, Merida State, in the Andes of Venezuela. The new species can be diagnosed from its closely resembling Aromobates meridensis by being a smaller frog, bearing conspicuous lateral dermal folds on toes, having the tympanum with paler coloration, larger dark brown dorsal spots, two irregular pale bands from upper eyelids to the level of shoulders, larger oblique pale inguinal band, throat and chest with inconspicuous spots made up of fine dark stippling that do not form well-defined spots; ventral surfaces of arms and thighs almost immaculate, tarsal fold evident, more extended foot web, tip of snout more acute, and metacarpal tubercle more pronounced.


[Spanish/Español] Resumen: E. La Marca y L.M. Otero López. “Redescubrimiento de los ejemplares tipo de Colostethus meridensis, con descripción de una nueva especie emparentada y redescripción de Aromobates mayorgai (Amphibia: Anura: Dendrobatidae)”. En este trabajo discutimos el redescubrimiento de los tipos de Colostethus meridensis (= Aromobates meridensis), que por mucho tiempo se creyó estaban perdidos, damos una redescripción de su holotipo, y redescribimos una especie simpátrica, Aromobates mayorgai, un taxón previamente conocido sólo por sus ejemplares tipo. Adicionalmente, describimos una especie nueva proveniente de las montañas de Piñango, Estado Mérida, en los Andes de Venezuela. La nueva especie puede ser diagnosticada de la muy parecida Aromobates meridensis por ser una rana más pequeña, con pliegues dérmicos a los lados de los dedos el pie, tímpano con coloración más clara, manchas dorsales pardo oscuras de mayor tamaño, dos bandas claras irregulares desde los párpados superiores hasta el nivel de los hombros, banda clara inguinal oblicua más larga, garganta y pecho con manchas inconspicuas conformadas por un fino punteado oscuro que no constituye manchas bien definidas; superficies ventrales de brazos y muslos casi inmaculadas, pliegue tarsiano evidente, membrana del pie con mayor extensión, punta de la nariz más aguda, y tubérculo metacarpiano más pronunciado.

NEW AMPHIBIAN DISCOVERIES FROM THE BIODIVERSE PHILIPPINES

The tropical forests of Philippines still amaze us with new biological discoveries. A study aimed to generate inventories of the biological diversity in Leyton Province has revealed a high endemicity of plants and vertebrates. Among the 64 species of herpetofauna, two frogs turn out to be new to science.
Both wrinkled ground frogs belong to the genus Platymantis, with about 70 species known to occur, besides Philippines, only on Papua-New Guinea (Papua and Indonesia) and the islands of Admiralty, Bismarck, Fiji, Palau and Solomon.

MOUNTAIN CHICKENS: WELCOME BACK TO THE ISLAND!

Leptodactylus fallax, a large frog inhabiting the Caribbean island of Montserrat, have declined by 80% and is listed as Critically Endangered on the IUCN Red List of Threatened Species™. 


Once an abundant species in the wild, it went to the brink of extinction mainly to human consumption (hence its common name of mountain chicken) and because of a deadly fungal infection by Batrachochytrium dendrobatidis.
A sotck of 50 frogs from an uninfected wild population was taken out of the island for ex-situ breeding purposes.  33 healthy offsprings born in captivity were released last January 2012 back into the island, and a field team have been tracking their movements.

NEW PANAMANIAN FROG STAINS BRIGHT YELLOW

A new frog species from western Panama, recently discovered by a team of herpetologists from the Senckenberg Research Institute in Frankfurt am Main, Germany, resulted in a weird discovery. When handled, the amphibian stains the fingers in bright yellow. The purpose of this dye is unknown.





The new species has been named Diasporus citrinobapheus, is a member of the family Eleutherodactylidae, well known because of the reproductive startegy of skipping the larval stage giving birth tiny froglets directly from eggs. The new especies is about 2 cm long, which makes it difficult to find.

GIANT SIDE-NECKED FOSSIL TURTLE, 60 MILLION YEARS OLD, FOUND IN COLOMBIA

Although formally described in 2005 (under the name Carbonemys cofrinii, in reference to the coal mine in Cerro Cerrejón, northern Colombia, where it was discovered) it was not until recently when the largest specimen (measuring 172 centimeters, or about 5 feet 7 inches, long) was found.

This giant lived five million years after the dinosaurs vanished, along with other large reptiles like giant boas and crocodiles. Scientists believe that a combination of fewer predators, larger habitat area, plentiful food supply, and climate changes, along other changes in the ecosystem, worked together to allow these giant species to survive.

The Fifth Asian Herpetological Conference

The Fifth Asian Herpetological Conference will be held on 2-4 June 2012 in the city of Chengdu, western China. 
The conference will be joined by the Annual Meeting of the Chinese Herpetologist Society and hosted by the Chengdu Institute of Biology and the Chinese Herpetologist Society.
The conference is the largest regional herpetological gathering of the Asian and Pacific area and we anticipate that 250-300 herpetologists will attend the conference. This is a wonderful opportunity to meet friends, exchange ideas and establish collaborations. In addition to regular presentations, several workshops are also planned, which will provide a learning experience for students. The first Asian Herpetological Research editorial board meeting will be held at the same time.

The copper striped blue-tailed skink (Emoia impar) is the latest vertebrate species extinct from the Hawaiian tropical archipelago

"The copper striped blue-tailed skink (Emoia impar) — a sleek lizard with smooth, polished scales and a long, sky-blue tail — was last confirmed in the Na’Pali coast of Kauai in the 1960s. But repeated field surveys on Kauai, Oahu, Maui and Hawai’i islands from 1988 to 2008 have yielded no sightings or specimens". Read more at: Damon Tucker.Hawaiian News

ONE OF THE LAST TWO RABB'S FRINGE-LIMBED TREE FROG DIED IN CAPTIVITY

The Rabbs' fringe-limbed tree frog (Ecnomiohyla rabborum) was identified by Zoo Atlanta's herpetology curator Joseph Mendelson during a 2005 trip to Panama, and formally described to science in 2008. It was already a non-common species when discovered, probably due to a a fungus pathogen outbreak where it occurs. It has not been observed in the wild since 2007 and it is believed to be extinct.


Only two specimens were known to be alive outside its natural habitat, both kept in the botanical garden in Atlanta, USA. Unfortunatelly, one of them die due to ill health, although it was preserved for future genetic studies.

NEW DWARF CHAMELEONS AMONG THE SMALLEST TERRESTRIAL VERTEBRATES
From the paper's 'background': "One clade of Malagasy leaf chameleons, the Brokesia minima group, is known to contain species that rank among the smallest amniotes in the world. We report on a previously unrecognized radiation of these miniaturized lizards comprising four new species described herein".

A NEW LIZARD SPECIES FROM PERU


A new lizard species of the genus Potamites has been described from the montane forests of the Cordillera de Vilcabamba (Cusco region) and Apurimac River valley (Ayacucho region), between 1500 and 2000 meters of elevation, in southern Peru.

THE WORLD'S SMALLEST VERTEBRATE IS A TROPICAL FROG


Two new species of diminutive terrestrial frogs were recently discovered from the megadiverse hotspot island of New Guinea. One of them, Paedophryne amauensisrepresents the smallest known vertebrate species, attaining an average body size of only 7.7 mm.

The genus Paedophryne, also recently described, has four species which are among the ten smallest vertebrates, rendering it the most diminutive genus of amphibian anurans. Minute frogs, in general, seem not to be just 
mere oddities, but represent a previously unrecognized ecological guild.
