More assassins on the radar: As many as 24 new species of assassin bugs described

July 11, 2016

As many as 24 assassin bugs new to science were discovered and described by Dr. Guanyang Zhang and his colleagues. In their article, published in the open access Biodiversity Data Journal, they describe the new insects along with treating another 47 assassin bugs in the same genus. To do this, the scientists examined more than 10,000 specimens, coming from both museum collections and newly undertaken field trips.

Assassin bugs are insects that prey upon other small creatures, an intriguing behavior that gives the common name of their group. There are some 7000 described species of assassin bugs, but new species are still being discovered and described every year.

The new species described by scientists Drs Guanyang Zhang, University of California, Riverside, and Arizona State University, Elwood R. Hart, Iowa State University, and Christiane Weirauch, University of California, Riverside, belong to the assassin bug genusZelus.

Linnaeus, the Swedish scientist, who established the universally used Linnean classification system, described the first species (Zelus longipes) of Zelus in 1767. Back then, he placed it in the genus Cimex, from where it was subsequently moved to Zelus. All of Zhang & Hart's new species are from the Americas. Mexico, Panama, Peru, Colombia and Brazil are some of the top countries harboring new species.

To conduct the research, Zhang examined more than 10,000 specimens and nearly all of them have been databased. These specimen records are now freely and permanently available to everybody. Zhang's work demonstrates the value of natural history collections. The specimens used in his work come from 26 museums in nine countries. The discovery of the new species would not have been possible without these museums actively collecting and maintaining their insect collections.
