The updated checklist of the marine crabs of Guinea-Bissau presented in this work is the result of consolidating decades of research, ongoing systematic revisions of the regional carcinofauna, and the inclusion of new records. DNA markers and morphological analyses for accurate identifications are integrated. Sixty-one species are mentioned in this list after reviewing specimens from scientific collections and literature. Of these 61 species listed, the presence of 51 species in Guinea-Bissau is confirmed, and 21 are reported for the first time in the area. A total of 98 sequences were obtained from 41 species (51 of 16S for 38 species and 47 of COI for 35 species), and 48 sequences (24 of 16S and 24 of COI) were the first ones obtained for 29 species. The maximum or minimum bathymetric range is expanded by 16 species, and for other six species, a color description is provided for the first time. Merocryptus obsoletus is synonymized as Merocryptus boletifer. The present study will be a useful baseline for gathering further ecological information about globally important marine taxa, not only in Guinea-Bissau but about African brachyurans in general.

The taxonomic status of the sergestid shrimp, Acetes americanus, has been questioned for several decades. No specific study has been performed thus far to resolve the incongruences. This species has a wide geographical range in the western Atlantic and is represented by two formally accepted subspecies: Acetes americanus carolinae, distributed in North America, and Acetes americanus americanus, present in South America. However, there are regions where the coexistence of both subspecies has been reported, such as Central America. This study aimed to genetically compare specimens of A. a. americanus collected in South America with A. a. carolinae sampled in North America to check for possible differences and the existence of more than one subspecies of A. americanus on the Brazilian coast. Based on the sequences of two informative markers, the cytochrome oxidase I region (COI) and 16S rRNA, phylogenetic reconstruction demonstrated well-defined clades with high support values, reinforcing the idea that A. a. americanus is genetically different from A. a. carolinae. Our hypothesis was corroborated as the specimens collected in Brazil were divided into two distinct lineages: the first composed of A. a. americanus sensu stricto (Brazil 1) and the second by Acetes americanus (Brazil 2). The three groups evidenced in the haplotype network were the same as those observed in the phylogenetic tree. The morphometric character (height/length of the thelycum) was effective in distinguishing A. a. Brazil 1 from A. a. carolinae. However, more detailed and conclusive studies comprising other characteristics to propose and describe a possible new entity are necessary. To the best of our knowledge, for the first time, the results of this study provide some insights into the taxonomic status of the sergestid shrimp A. americanus in the western Atlantic.

“…Adults occur in drainage channels close to the coastland, in the substrate with sandy or bedrock, at the marginal and open and sparse vegetation or in a narrow border of macrophytes. Its geographic distribution covers the Atlantic coast of the Americas, from the Southern United States (North Carolina, Florida, Mississipi, Louisiana, Texas), where the animals were introduced (Bowles et al, 2000;Holthuis, 1952;Villalobos, 1969), Mexico, Puerto Rico, Guatemala, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Guyana, Suriname, French Guian to southern Brazil -from Amapá to Rio Grande do Sul (Anderson & Filingame, 1980;Bowles et al, 2000;Holthuis, 1952;Holthuis & Provenzano, 1970;Mantelatto et al, 2022;Ortmann, 1897;Valencia & Campos, 2007;Villalobos, 1969;Williams, 1984).…”

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

Males of Macrobrachium olfersii have a large cheliped (second pereiopod) with individual variations in shape and ornamentation, and they vary in size within and between populations. Some misidentification or doubts about taxonomic validity occur due to this morphological variability throughout their geographic distribution. We carried out a morphometric analysis to detect specific patterns and the potential occurrence of morphotypes in M. olfersii from different populations. Our data set included 52 females and 109 males collected in the Neotropical region, between the north and south limits of Brazilian territory, in coastal rivers from the states of Rio Grande do Norte, Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Paraná and Santa Catarina. Body measurements were size standardized by allometric methods and explored by the principal component analysis (PCA) and non‐hierarchical analysis of K‐means clustering and canonical variate analysis (CVA). Our results suggested three distinct morphological groups (morphotypes) only for males in M. olfersii. Furthermore, the confirmation of monophyly of the different populations of M. olfersii was accomplished by sequences of 16S rDNA. Additional studies about relative growth in other populations and the analysis of the entire ontogenetic development of males in the laboratory will be important to complement the knowledge about morphotypes in this species.
