A new species of inseminating catfish of the genus Tympanopleura (Siluriformes: Auchenipteridae) from the Ituxi River, Amazon River basin, northern Brazil, revealed by integrative taxonomy

Journal of Fish Biology, Volume 109, Issue 1, Page 520-530, July 2026.
Abstract A new species of the genus Tympanopleura is described from the Iquiri River, a tributary of the Ituxi River, a right‐bank tributary to the Purus River, Amazon River, northern Brazil. The new species is distinguished from all its congeners by a combination of features, such as the presence of an intensely pigmented square‐shaped blotch on the ...

Little devils of Neotropical forests: A first molecular phylogeny of stygnid harvestmen with UCE‐museomics and a gigamatrix approach (Arachnida, Opiliones, Stygnidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First family‐wide phylogenomic framework of Stygnidae using UCE‐museomics and a gigamatrix approach establishes a novel three‐subfamily classification, erecting the new subfamily Auraninae subfam. nov. Signatures of severe incomplete lineage sorting and short deep internodes suggest a rapid early‐burst Neotropical radiation, driving phylogenetic ...

Evolution of the false‐leaf katydids (Orthoptera: Tettigoniidae: Phaneropterinae): Molecular phylogeny and divergence times

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic and divergence times analyses based on molecular data of five molecular markers recover Phaneropterinae as monophyletic, originating approximately 91.2 million years ago. From 31 analysed tribes, only three were recovered as monophyletic, whereas others showed extensive polyphyly, requiring substantial taxonomic revision.

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

Developmental Dynamics, Volume 255, Issue 6, Page 602-615, June 2026.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Integrative taxonomy reveals two new species of whiptail catfishes Loricaria (Siluriformes: Loricariidae) from northeastern Brazil

Journal of Fish Biology, Volume 108, Issue 6, Page 2080-2097, June 2026.
Abstract Two new species of whiptail catfish, Loricaria (Siluriformes: Loricariidae), were discovered in the Munim and Itapecuru river basins, Maranhão State, northeastern Brazil, through an integrative taxonomic approach combining morphology and mitochondrial DNA.

Host–Parasite Interaction Networks of Helminths of Sigmodontine Rodents in Two Different Areas of the Brazilian Atlantic Forest

Ecological Research, Volume 41, Issue 3, May 2026.
Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...
