Summary: This study describes nine new species of Nilothauma Kieffer, based on adult males collected in Brazil and Mexico. It also provides re-descriptions of Nilothauma aleta Roback, 1960 and N. duena Roback, 1960, along with an emended diagnosis of Nilothauma and a key to the males of all known species.

Summary: This article emphasizes the importance of taxonomy research on the Neotropical subtribe Euptychiina and presents the most complete phylogenetic tree to date through analyzing genetic sequences of 1280 specimens. The study reveals widespread paraphyly and polyphyly among the group, highlighting the need for a robust classification system to support taxonomic revisions at the species level.

Summary: Most diversification within Molossus occurred relatively recently during the Pleistocene, with dispersal-extinction cladogenesis as the best-fit model. Geological and paleo-climatic events were important factors in Molossus diversification. Pleistocene refugia in South America and the formation of the Panama Isthmus likely played a role in speciation within Molossus.

Summary: Myzomorphus Salle is a genus of prionine longhorn beetles composed of nine species. Two species, M. scutellatus and M. quadripunctatus, have wide distributions across Central to South America and show high polymorphism. By combining molecular and morphological data, the authors reconstructed the phylogeny of Myzomorphus and found that the variability of M. birai, M. scutellatus and M. quadripunctatus represents polymorphisms of a single species. They propose the synonymy of M. birai and M. scutellatus under M. quadripunctatus and emphasize the importance of multiple lines of evidence in taxonomic studies of polymorphic species.

Summary: This study explores the phylogenetic relationships of the subfamily Centrotinae based on mitochondrial genome data. The analysis suggests that Membracoidea, Smiliinae and Centrotinae, along with tribes Centrotypini and Leptobelini, form well-supported monophyletic groups.

Summary: Animals recognize familiar individuals to perform important social behaviors through communication between signalers and receivers. Research on closely related territorial poison frogs revealed that male golden rocket frogs exhibit recognition of conspecific neighbors' advertisement calls and show a dear enemy effect, while male Kai rocket frogs do not. This suggests that social recognition systems may have evolved differently in closely related species based on adaptations in both signalers and receivers.

Summary: The study investigates how deforestation impacts fish communities in French Guiana rivers and streams using environmental DNA metabarcoding. The results show that deforestation alters the functional diversity of freshwater fish communities, affecting the amount, identity, and internal structure of functional traits. Stream fish assemblages experience a reduction in functional redundancy, while river fish faunas experience a decline in functional richness and a loss of species with extreme functions. These findings suggest that deforestation can negatively impact the functioning and stability of neotropical freshwater ecosystems.

Summary: Based on the examination of types and additional specimens, new synonymies and revalidation are proposed in the genus Brontostoma Kirkaldy, 1904. The previous synonym of Brontostoma venusta with B. discus is confirmed, and Brontostoma discus is recorded from French Guiana for the first time. Brontostoma cicheroi is similar to B. discus but further taxonomic conclusion couldn't be achieved due to the unavailability of its holotype.

Summary: In this study, the taxonomy of Tipula (Vestiplex) subgenus in Taiwan was revised, and 18 species, including six new species, were recognized. The DNA barcode sequences were also provided. Sixteen out of the 18 species are endemic to Taiwan, and the species group shows closest biogeographic relationships to the Qinghai-Tibetan Plateau.
