Gil-Santana H.R. et al.: "Valentina aline gen. nov., sp. nov., a new genus and species of cave-associated Emesinae (Hemiptera: Heteroptera: Reduviidae) from Brazil".

A new cave-associated genus and species of Emesinae, Valentina aline gen. nov., sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae), is described from the State of Minas Gerais, Brazil, based on four males and six female specimens. In addition to the taxonomic description, we provide ecological notes on the subterranean habitats in which the specimens were recorded. We further highlight potential conservation concerns affecting these sites, emphasizing the vulnerability of subterranean ecosystems to ongoing anthropogenic pressures.

Gil-Santana H.R.: "A new species of Racelda Signoret, 1864 with taxonomic notes on Racelda aberlenci Bérenger & Gil-Santana, 2005 and Racelda robusta Bérenger & Gil-Santana, 2005 (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae)".

Racelda jaderi sp. nov. (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae) is described from French Guiana based on six male specimens. Short taxonomical notes on Racelda aberlenci Bérenger & Gil-Santana, 2005 and Racelda robusta Bérenger & Gil-Santana, 2005, are provided, with emphasis on their male genitalia, which are fully described for the first time.

Wang K. et al.: "Integrative Taxonomy of Pachygrontha (Heteroptera: Pachygronthidae) in East and Southeast Asia Reveals New Insights Into Species and Group Delimitation".

Species discovery and description are fundamental to biodiversity documentation and evolutionary studies. Integrative taxonomy synthesizes morphological, genomic, and ecological evidence to provide a robust framework for testing species hypotheses and delineating boundaries in closely related lineages, thereby not only advancing taxonomic practice but also enabling critical evaluation of species group concepts. Here, we present a comprehensive assessment of the genus Pachygrontha Germar, 1838 in East and Southeast Asia using an integrative approach that combines detailed morphology with complete mitochondrial genomes and genome-wide SNPs. Our study confirms the existence of eight species, including six previously recognized species and two new species described herein as P. chuanxiensis Wang & Bu, sp. nov. and P. ruiliensis Gao, Wang & Bu, sp. nov. Phylogenetic analyses reveal instances of mito-nuclear discordance and provide insights into the utility and limitations of historically defined species groups within Pachygrontha. Through examining differentiation at both the interspecific and closely related species-levels, our integrative analysis provides a foundational assessment of divergence levels within the genus and establishes a basis for future broader surveys and more comprehensive taxonomic revisions.
