Remarkably Large And Colorful New Species Of Beetle Discovered In Guyane
Scientists from the Smithsonian Institution describe the Spectacular Guyane False-form beetle, or Guyanemorpha spectabilis, from Guyane (French Guiana). As its name suggests, the newly discovered species stands out among its dull relatives in the Western Hemisphere, with its great size and beautiful coloration. The study was published in the open access journal ZooKeys.
The new species belongs to the Pseudomorphini Tribe, famous for the co-existence of its representatives with various ant species. Members of G. spectabilis occur at lowland rainforest sites in French Guiana and are accordingly most likely to live with ants, although at present nothing is known about their way of life.
"The pseudomorphines are a very interesting evolutionary off-shoot of the normal carabid morphotype in both form and function and are only just now beginning to be understood in North America. The fact that species of related genera in South America are living with arboreal ants will make learning about them far more difficult. Insecticidal fogging gets adults of these species, but only tearing apart arboreal Azteca ant nests while suspended in a tree will produce their larvae, and that is not for carabidologists faint of heart," explains the author Dr. Erwin, and his Intern, Lauren Amundson.
