Taxonomic Updates of Thismia pseudomelanomitra (Thismiaceae) Reveal an Old Acquaintance From the Ecuadorian Amazon

open access: yesFeddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...

Scheffrahnitermes ubuntu (Isoptera: Apicotermitinae), Description of a New Termite Using a Collaborative Approach to Address the Wallacean Shortfall

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
The study of Neotropical Apicotermitinae remains challenging due to the large number of undescribed taxa (Linnean shortfall) as well as the scarcity of distributional data (Wallacean shortfall). Despite recent efforts to reduce the first one, the second remains an even more significant challenge.

Spatial Ecology and Habitat Selection by Jaguars and Pumas in a Protected Area in the Atlantic Forest of Brazil

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding animal distribution is crucial for elucidating natural history, population dynamics, and inter‐ and intraspecific interactions. This knowledge informs the planning and evaluation of management and conservation strategies, particularly for sympatric, scarce, and threatened species such as jaguars (Panthera onca) and pumas (Puma ...

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

open access: yesJournal of Fish Biology, Volume 108, Issue 6, Page 1906-1933, June 2026.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...
