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.

“…Japanese beech (hereinafter simply referred to as beech) is the dominant tree species in the cooltemperate zone of Japan. It is crucial to preserve beech forests for their water retention function as well as for conservation of genetic diversity (Yoshii & Tamai, 1994), ecosystem diversity, and various forest resources, which are specific to cool-temperate forests. However, under the policy of expanding forestation of the 1950s, beech forests were clear-cut over large areas (Murai et al, 1991).…”

The aim of this study was to clarify the structure and regeneration status of mixed beech (Fagus crenata) forest on Mt. Toishi in the Sangun mountain range in northern Kyushu, a relatively low‐latitude region in Japan, with emphasis on forests at lower elevations. We focused on a mixed beech forest at a low elevation of Mt. Toishi and compared the forest structure of the target stands, including tree species and size, with the forest structure near the peaks of Mt. Toishi and Mt. Sangun. Deciduous broad‐leaf trees were dominant near the peaks, while evergreen broad‐leaf trees dominated at lower elevations, whereas the relative dominance of beech trees was not significantly different. Near the peaks, the number of large‐diameter beech trees forming the canopy decreased, and small‐diameter trees were present. The proportion of small‐sized trees was lower in the low‐elevation forest area than in the forest area near the peak. Even at lower elevations, juvenile beech trees grew in limited areas on steep slopes along forest roads. These sites suggested that regeneration of beech populations is possible even at low elevation.
