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.

A thorough polyphasic taxonomic study, integrating genome-based taxonomic approaches, was carried out to characterize the RB5 strain isolated from root nodules of growing on the coastal dunes of Bousfer Beach (Oran, Algeria). The 16S rRNA gene sequence analysis revealed that strain RB5 had the highest similarity to LMG27940 (98.94%) and IzPS32d (98.

A crude oil aggregation-forming, strictly anaerobic, Gram-stain-positive, spore-forming, rod-shaped, motile and mesophilic bacterium, named strain SH18-2, was isolated from marine sediment near Sado Island in the Sea of Japan. The temperature, salinity and pH ranges of this strain for the growth were 15-40 °C (optimum 35 °C), 0.5-6.

The filamentous red algal genus Bryocladia was recently deeply revised based on molecular and morphological data. However, data from the Southwestern Atlantic Ocean are scarce. Here, we provide a phylogenetic study of Bryocladia representatives from the Brazilian coast with new additions to the genus.
