Hallan 46 nuevas especies en Surinam


(Species not new to science) Leaf beetle (Stilodes sedecimmaculata) is found only in the Guyana Shield. There are over 35,000 leaf beetle species in the world, and many feed only on a particular type of host plant. The beetles store toxic chemicals from the plants they eat in their bodies, and advertise this toxicity with bright colors to warn off predators. This species was observed during Conservation International's Rapid Assessment Program in southwest Suriname in August and September 2010. www.conservation.org © Trond Larsen PERMITTED USE: This image may be downloaded at no charge for one-time use for coverage/promotion of the press release titled “An Armored Catfish, a ‘Cowboy Frog’, and a Rainbow of Colorful Critters discovered in Southwest Suriname” by Conservation International.

(Species not new to science) Coprophanaeus lancifer is the largest dung beetle species in the Neotropics. While weaponry in most animal species is restricted to males, females of this species possess a long head horn which they use to battle with other females over carrion (animal carcasses). Males also use a long horn to fight over females. With an enormous thorax filled almost entirely with muscle, C. lancifer is incredibly strong. Where the species is common, it may bury an animal carcass as large as a pig in only a few days. This species was observed by scientists working with Conservation International's Rapid Assessment Program in southwest Suriname in September 2010. www.conservation.org © Piotr Naskrecki PERMITTED USE: This image may be downloaded at no charge for one-time use for coverage/promotion of the press release titled “An Armored Catfish, a ‘Cowboy Frog’, and a Rainbow of Colorful Critters discovered in Southwest Suriname” by Conservation International.

El pequeño país sudamericano es tierra virgen. Investigadores hallaron peces, insectos y anfibios potencialmente nuevos para la ciencia.

Caballito del diablo. Hallaron cuatro especies nuevas de este género pariente de las libélulas.
Peces, insectos y anfibios tan raros como bellos. Un grupo de científicos, indígenas y estudiantes dirigidos por la ONG Conservation International(CI) descubrió 46 nuevas especies de animales en los densos bosques del sur de Surinam, América del Sur (ver galería de imágenes).
La expedición realizó los hallazgos en los ríos Koetari y Sipaliwini, donde también descubrió nuevos petroglifos en la frontera con Brasil.
Entre las nuevas especies se encuentra la "rana cowboy", un anfibio con franjas blancas en sus piernas y una estructura similar a un espolón en el talón.
También el multicolor "saltamontes crayola". Es el único saltamontes que utiliza defensas químicas para repeler mamíferos y aves predadoras.
(Species not new to science) A mating pair of tortoise beetles (Cyrtonota lateralis), named after the broad dorsal surface that covers and protects them like a tortoise shell.

It has an exceptionally wide mouth, which allows it to swallow prey that is nearly as large as its own body, including mice and other frogs.

Un bagre con un escudo antipirañas. Tiene placas óseas cubiertas con espinas en todo el cuerpo para defenderse de los peces depredadores.
Caballitos del diablo. Similares a las libélulas En la expedición a Surinam se encontraron cuatro nueva especies del género Argia.
"Como científico es emocionante realizar investigaciones en áreas tan remotas donde hay infinidad de nuevos descubrimientos por hacer", dijo Trond Larsen, director del Programa de Evaluación Rápida (RAP, por su sigla en inglés), de tres semanas de duración, que realizó los estudios.
La zona sur de Surinam es virgen ya que no hay caminos o carreteras oficiales y el lugar está mayoritariamente deshabitado, señaló Larsen.
Los petroglifos fueron hallados en cuevas cerca del pueblo Kwamalasamutu de los indígenas Tiriyó, un sitio que la CI busca preservar, junto a las comunidades locales, como un destino ecoturístico.
Ecoturismo. La directora de CI-Surinam, Annette Tjon Sie-Fat, cree que el informe tendrá un papel crucial en la conservación y gestión de la zona como patrimonio cultural y como destino único para el turismo, un proyecto que la CI impulsa.
En 2007, otro programa RAP patrocinado por el CI en Surinam resultó en el descubrimiento de 24 nuevas especies de animales.

(Species not new to science) Monkey frog (Phyllomedusa tomopterna) is a species of tree frog that is indicative of healthy, pristine rain forest.

(Species not new to science) Females of this orb weaving spider (Micrathena cyanospina) are very large and are adorned with an incredibly long pair of metallic blue spines. Males, in contrast, are tiny.

(Species not new to science) This beautiful green crested katydid (Steirodon sp.) is an obligate herbivore, eating only plants. Its spiny body helps defend it from birds and other animals that want to eat it. Katydids sing at night to attract mates.

(Species not new to science) Three-striped poison dart frog (Ameerega trivitatta) carrying tadpoles on the back. Adults of many poison dart species transport their young from one body of water to another as the tadpoles feed and develop.
