Barbacenia rupestris (Velloziaceae), a new species from a prehistoric site in the Espinhaço Range, Minas Gerais, Brazil FERREIRA-JÚNIOR, CARLOS ALBERTO; ZAVATIN, DANILO ALVARENGA; Jefferson Prado; BRAGANÇA, GRACIELLE PEREIRA PIMENTA; ISAIAS, ROSY MARY DOS SANTOS; CABRAL, ANDRESSA; SILVA, RENATO RAMOS Phytotaxa (on-line), v. 747, n. 3, p. 277-288, 2026 DOI Palavra-chave: campos rupestres; conservation; Espinhaço Setentrional; Flora of Brazil; Pandanales Áreas do conhecimento: Ciências Biológicas; Botânica; Taxonomia Vegetal; Taxonomia de Fanerógamos resumo ... (en) Floristic surveys near Monte Azul, Minas Gerais, have revealed a magenta-flowered Barbacenia inhabiting rocky outcrops bearing prehistoric paintings. The new species resembles B. tomentosa and B. luzulifolia in phyllotaxy and hypanthium size but differs mainly by its vivid corolla and reduced corona. Here, named Barbacenia rupestris, the new species epithet refers both to its rupicolous habitat and the prehistoric paintings.

ErythroCite: a database on red blood cell size of fishes Félix P Leiva; Felix C. Mark; Rafael Molina-Venegas; Katharina Alter; Carolina Arruda de Oliveira Freire; A.

Size is a fundamental trait in biology, and cell size plays a key role in cellular functions, influencing physiological adaptations and evolutionary processes in living organisms. For decades, scientists have been fascinated by the considerable variation in cell sizes among animals, yet systematic efforts to compile such data have been scarce. To address this gap, we employed a systematic map approach to create ErythroCite, an open-source database of fish erythrocyte sizes. This comprehensive resource encompasses 1,764 records from 660 species among four major lineages: Actinopterygii, Chondrichthyes, Dipnoi, and Cyclostomata. Our findings reveal a remarkable 414-fold range in cell volume, with most studies on bony fishes and limited data on juveniles and earlier life stages. Life stage and sex were infrequently reported, but available data showed equal representation of adult of females and males. ErythroCite offers valuable insights for studies in macroecology, macrophysiology, comparative physiology, evolutionary biology and cell biology. We anticipate this resource will facilitate comparative approaches and meta-analyses, globally driving further exploration of erythrocyte diversity and function in fish.

First record of Hister cavifrons Marseul, 1854 (Coleoptera: Histeridae) for Santa Catarina's Island, Brazil VARELA, MARIA E. S.; HESSELN, SOL G.; Fernando Willyan Trevisan Leivas; PINTO, CARLOS J. C.

(en) Hister cavifrons Marseul, 1854 (Coleoptera: Histeridae) is a common species in Brazilian territory mostly associated with animal carcasses that has previously been recorded in the Amazon, Atlantic Forest, and Cerrado biomes across several Brazilian states, ranging from the North to the South of the country. The highest number of records is from the state of Paraná, while Santa Catarina has only two records from inland municipalities. This note presents the first record of H. cavifrons on the coast of Santa Catarina specifically in the municipality of Florianópolis and the third for the state. The species was sampled in Biguá [Nannopterum brasilianum (Gmelin, 1789) (Suliformes: Phalacrocoracidae)] carcass, an aquatic bird commonly found along the Santa Catarina coast, marking the first record of this species associated with this animal, during the month of April (autumn season).
