Researchers have identified two new beetle species, Metopiellus palamaku and Metopiellus chasqui, in Ecuador’s Amazon region and Andean cloud forests. This marks the first time the Metopiellus genus has been recorded in Ecuador, expanding scientific understanding of the country’s biodiversity.
The discoveries were made in Napo province within the Amazon rainforest and in Pichincha province’s cloud forests. These findings resulted from studies focusing on fauna living among leaf litter in tropical ecosystems. Previously, this beetle genus had only been documented in Brazil, Colombia, and Argentina.
The research was conducted by scientists from Pontificia Universidad Católica del Ecuador, Fundación Uru, Instituto Nacional de Biodiversidad (INABIO), and Clemson University. According to the researchers: “The discovery shows that even among small groups of insects there are still species yet to be identified in the country.”
One of the species was found in cloud forests on the western slope of the Andes. This represents a significant expansion for the genus not only geographically but also ecologically, highlighting these ecosystems’ high diversity.
The names chosen for these beetles reflect Ecuador’s cultural heritage: ‘palamaku’ comes from a Kichwa legend about a deity considered to be the origin of insects; ‘chasqui’ refers to messengers from the Inca Empire.
According to those involved: “This discovery reinforces the importance of scientific research for conserving biodiversity and protecting Ecuador’s natural heritage.” The full study is available here
