1953 was the last time any researcher saw a Cropan’s boa (Corallus cropanii) alive, which lives in Brazil’s Atlantic Forest south of São Paulo. Since then, the snake—thought to be the rarest boid in the world—has been recorded by scientists just five times. In January, a 1.7-meter-long female was captured by a group of rural workers in January.  The recently-captured boa is lucky: One of its captors was about to hack it to death, when the other two recalled “wanted signs” that had been posted by researchers from the University of São Paulo’s Museum of Zoology and the Butantan Institute,Read More

Recent field collections in the Rio Jarguaribe basin confirmed the presence of the pale-spotted specimens and its distinctiveness as a new species.

Arachnids, New Species March 7, 2017 at 11:26 pm

The Avicularia group contains species of tarantula that live in trees and eat a range of food including insects, bats and even small birds. One of the new species is named after by naturalist Maria Sybilla Merian (1647-1717) depicting an Avicularia avicularia spider eating a bird (below). Dr Fukushima, the lead author of the research, said: ‘This illustration gave origin to the name of the genus and the popular name birdeater spiders. People (in) that time did not believe in her observations, saying that a spider eating a bird was a female fantasy. But now we know she is right!’Read More

Insects, New Species February 1, 2017 at 9:14 am

A new genus of firefly is described, from the rainforests of Brazil. “Fireflies or sometimes named lightning bugs are not flies. They represent a family of beetles (Lampyridae) whose members have the ability to use bioluminescence during twilight to attract mates or prey. They produce a “cold light”, with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red. So far about 2000 firefly species have been found and described.”
