The taxonomy of the Brazilian aeglid species Aegla paulensis Schmitt, 1942 from two disjunct hydrographic basins is revised using morphological and molecular data. Results show that six disjunctive populations of Aegla paulensis form a species complex. Aegla paulensis sensu stricto is redescribed and Aegla rosanae Campos Jr., 1998 is revalidated. The four remaining populations previously assigned to Aegla paulensis are now recognized as different species, namely Aegla vanini n. sp., Aegla japi n. sp., Aegla jaragua n. sp. and Aegla jundiai n. sp. All new species are described and illustrated and are well supported by both morphological and molecular data. Aegla lancinhas Bond-Buckup & Buckup in Santos et al., 2015, which until recently was confounded with Aegla paulensis s. str., is supported as a valid species. A key to all members of the A. paulensis species complex is provided, and their phylogenetic and biogeographic relationships to other closely related species is discussed.

Integrated morphometric and molecular analyses indicate three male morphotypes in the freshwater prawn Macrobrachium olfersii (Decapoda, Palaemonidae) along the Brazilian neotropical region

Natalia Rossi, Joao Alberto Farinelli Pantaleao, Fernando L. Mantelatto

Summary: Males of M. olfersii exhibit morphological variability and can be classified into three distinct morphological groups based on morphometric analysis and genetic sequencing.

Demographic changes and life-history strategies predict the genetic diversity in crabs

Pedro A. Peres, Fernando L. Mantelatto

Summary: Studying the predictors of genetic diversity in crabs, population size fluctuation was found to be the most critical factor, with species that have undergone bottlenecks and population expansion showing lower genetic diversity. Egg size, pelagic larval duration, and habitat may also play a role in genetic diversity. This study adds to our understanding of the predictors of genetic diversity by examining a marine invertebrate group.

Additions to the Morphology of the Cucumariidae. I. Intraspecific Variation of the Retractor Muscle in Parathyone braziliensis (Verrill, 1868) and Thyonidium seguroensis (Deichmann, 1930) (Holothuroidea: Dendrochirotida)

Luciana Martins, Marcos Tavares

Summary: The intraspecific variation of the gross morphology of the retractor muscle was studied in Parathyone braziliensis and Thyonidium seguroensis. Contrary to early expectations, anatomical evidence did not support the idea that the point of origin of the retractor muscle and the split of the muscle bands could be used as age-related or taxonomic characters to differentiate species.

Summary: This study investigated the effects of sun corals on mobile invertebrates using an experimental approach. The results showed that the condition of sun corals did not affect the overall taxonomic composition, but did impact the diversity and abundance of certain species.

Evidence using morphology, molecules, and biogeography clarifies the taxonomic status of mole crabs of the genus Emerita Scopoli, 1777 (Anomura, Hippidae) and reveals a new species from the western Atlantic

Fernando L. Mantelatto, Juliana M. Paixao, Rafael Robles, Jeniffer N. Teles, Felipe C. Balbino

Summary: The taxonomic status and distribution of some species of the genus Emerita in the western Atlantic were uncertain. A thorough examination of morphological differences and genetic markers revealed a new species, Emerita almeidai, along the Brazilian coast. Molecular phylogenetic analysis showed that individuals previously identified as E. portoricensis were actually divided into two clades, one from the Brazilian coast and the other from Central America. This study increases the number of species in the genus Emerita to 12, with different distributions in the Atlantic, Indo-Pacific, and eastern Pacific.

Genetic variation and cryptic lineage among the sergestid shrimp Acetes americanus (Decapoda)

Sabrina Morilhas Simoes, Rogerio Caetano Costa, Fabricio Lopes Carvalho, Abner Carvalho-Batista, Sarah de Souza Alves Teodoro, Fernando L. Mantelatto

Summary: This study genetically compared specimens of Acetes americanus collected in South America with Acetes americanus carolinae sampled in North America. The results showed clear genetic differences between them, supporting the idea that A. a. americanus and A. a. carolinae are distinct subspecies. Additionally, a new subspecies, A. a. Brazil 2, was discovered on the Brazilian coast. Further research is needed to confirm and describe this new subspecies.

Latitudinal variation on reproductive performance of hermit crabs (Anomura: Paguroidea) in two marine provinces along the Brazilian coast

Felipe Bezerra Ribeiro, Helena Matthews-Cascon, Fernando Luis Mantelatto, Luis Ernesto Arruda Bezerra

Summary: We compared the fecundity and reproductive effort of two hermit crab species, Clibanarius antillensis and Calcinus tibicen, distributed along the Brazilian coast. Samples were collected at two locations separated by approximately 3000 km - Pedra Rachada Beach (Ceara) in the NE region and Araca Beach/Grande Beach (Sao Paulo) in the SE region. The results showed higher values for females of both species collected in the SE localities, with the presence of aberrant eggs affecting the reproductive parameters in NE females and resulting in lower reproductive effort. The variation in reproductive performance may be related to the latitudinal location and habitat characteristics.

Summary: This study assessed the Panopeus species in the Southwestern Atlantic using morphological and genetic data, providing updated diagnoses and clarifying phylogenetic relationships. The nonmonophyletic nature of the genus was confirmed, and the study highlighted the importance of an integrative approach for accurate identification.

Six new records of decapod crustacean species (Anomura, Brachyura) from southern Brazil

Daniel Lima, Harry Boos, Marcos Tavares

Summary: The geographic ranges of five anomuran and one brachyuran species collected from southern Brazil's continental shelf and slope have been extended southward. These species include Neolithodes agassisii, Paguristes spectabilis, Pagurus heblingi, Phimochirus occlusus, Mixtopagurus paradoxus, and Euchirograpsus antillensis. This expansion in range increases the diversity of hermit crabs and brachyurans in Santa Catarina, Brazil.

Marine and estuarine crustacean diversity and assemblage structure in eastern Brazil three years after the Fundao mining dam failure

Ronaldo Ruy Oliveira-Filho, Joelson Musiello-Fernandes, Helen Audrey Pichler, Mariana Antunes, Ciro Colodetti Vilar, Fernando Luis Mantelatto, Arthur Anker, Andre Pereira Cattani, Julien Chiquieri, Jean-Christophe Joyeux, Mauricio Hostim-Silva

Summary: The study examines the impact of the Fundao dam collapse on the species richness and assemblage structure of decapod and stomatopod crustaceans in the Rio Doce basin in Brazil. Samples collected from October 2018 to September 2019 showed that the dominant species in the community were Xiphopenaeus kroyeri. Species composition varied significantly among different locations, habitats, and seasons, with freshwater discharge playing a crucial role. The study highlights the need for long-term monitoring and emphasizes the difficulty in detecting and studying the effects of such disasters.

Extension of the known range of the snapping shrimp Alpheus christofferseni Anker, Hurt and Knowlton, 2007 (Caridea: Alpheidae)

Gabriel Lucas Bochini, Rodrigo Gueron, Mariana Terossi, Alexandre Oliveira Almeida

Summary: This study reports the collection of two Alpheus christofferseni specimens from Pernambuco, Brazil, increasing the knowledge of the species distribution along the Brazilian coast. The specimens were found approximately five latitudinal degrees south of the species' type locality, and also expanded the known bathymetric distribution from shallow intertidal to approximately 51 m. Morphological variation notes are provided based on the new material, and the first sequence of the 16S ribosomal subunit gene for the Brazilian coast is provided and compared with congeners.

Summary: In this study, species-specific primers were developed to analyze food-web interactions in a tropical shallow lake. The primers successfully amplified the DNA target of the microcrustacean preys and showed high specificity and sensitivity. This technique provides an efficient tool for food-web research and identification of zooplankton species from predator's digestive tracts.
