Wrapped in a shiny black color, a new beetle caught the attention of researchers Veragua Rainforest Reserve, located in Liverpool of Limon.
Is the species Galissus nigrescens, which has a size between 2 and 2.5 inches.
In this species, the genus called Galissus gets to have four total described around the world, two in South America and the other two belong to Central America, announced Ubirajara R. Martins, Maria Helena M. Galileo and Rolando Ramirez Campos in an article published in Papéis Avulsos of Zoology, scientific journal of the Zoological Museum of the University of São Paulo, Brazil.
Among the treetops; Galissus nigrescens is a type of beetle ‘horns’ long, a characteristic of the families Cerambycidae and Disteniidae.
It is not easy to see it. In fact, avoids trapping methods usually used by researchers in the reserve.
On a field trip, Julian Salazar (assistant Ramirez) noted that in the top of a tree (Casearia arborea) was taking a lot of insect activity around flowers.
Using a net, Salazar and Ramirez proceeded to capture them. Only at that time managed to count 33 species of longhorn beetles (long antennae) and among them, one that seemed to be new. “I saw it and I did not find a beetle known, I started to suspect (a new species),” Ramirez told.
Already in the lab, there were six copies of both males and females.
Some characteristics of the specimens were similar to the kind already described for Costa Rica and Panama, but this is a blue with black while Galissus nigrescens is shiny black with integument (type of skeleton that serves coated) red hue.
That makes beetles of the same genus but of different species.
For the moment, only nigrescens Galissus been reported in Costa Rica and thus is said to be endemic. The truth is that it is the first record that is known in the scientific guild, they say.
