Abstract

We describe a new species of Collembola, Crossodonthina elegans sp. nov., collected from Yonaguni-jima, southwest Japan. This new species differs from other known congeners because it has an unusual white or yellow color pattern on Ant. I and Th. I. It is similar to C. laterisensillata Ohira, Kataoka, Tanooka & Nakamori, 2022, in the structure of mouthparts, 3 + 3 eyes, cephalic chaeta O present, and tubercles De and Dl separated on Abd. V. However, it is easily distinguished from the latter species to maxilla without ciliated lamella, cephalic tubercle Dl separated from L and So, 5 chaetae of tubercle L on Abd. I and III, and macrochaetae apically rounded. We provide the key to all species of the genus and discuss the unique color pattern of the new species among the tribe Lobellini.
