Gerromorpha (Insecta, Hemiptera, Heteroptera) from eastern Maranh&atilde;o state, northeastern Brazil

The infraorder Gerromorpha (Insecta, Hemiptera, Heteroptera) comprises semiaquatic bugs, most of which live on the water surface, among floating plants or at the margins of water bodies. We made collections of these insects in the Itapecuru and Parnaíba hydrographical basins in eastern Maranhão state, northeastern Brazil, from January to December 2019. Based on the material obtained, we present new records for 23 species, 20 of which are recorded for the first time from Maranhão state.

Between 2003 and 2013 the occurrence of fish species were recorded through collection of specimens, landing records of the artisanal fleet, literature reviews and from specimens deposited in ichthyological collections. A total of 459 species from 2 classes, 26 orders, 102 families and 264 genera is listed, with 83 species (18% of the total number) recorded for the first time in the study area. Additionally, Halichoeres radiatus, Lachnolaimus maximus and Canthigaster jamestyleri are reported for the first time in the Brazilian coast and nine other species have their geographic distribution extended.

ABSTRACT A recent floristic survey of Rhodophyta from Ceará State, Brazil (02º46'30''-07º52'15''S and 37º14'54''-41º24'45''W), revealed the occurrence of 113 species distributed into 14 orders, 28 families and 63 genera. Of these, 18 species belonging to seven orders are new records; some of them poorly described and illustrated in the literature or cited only checklists. Therefore, aiming to expand the taxonomic knowledge about these poorly known species, we present detailed descriptions, illustrations, and comments on related taxa. The occurrence of Ceratodictyon scoparium is confirmed for the South Atlantic coast. The male gametophytes of Dohrniella antillarum var. brasiliensis and tetrasporophytes of Gracilariopsis silvana are illustrated for the first time. Ceramium fujianum is a new addition to northeastern Brazil. Among the new records, Callithamnion corymbosum, Ceramium clarionense, C. fujianum and C. scoparium showed a significant expansion of their geographic distribution along the Brazilian coast. Most of the newly recorded species are filamentous, small-sized or tufted algae, highlighting the need for new collections to detect the presence of these components.

Abstract Mangrove swamps and forests cover over 137,000 km2 distributed latitudinally among subtropical zones, 7% of which are in Brazil, with a greater density in the country’s northernmost region. Considering that the community of Myxomycetes recorded for this environment is hardly known, three areas located in the state of Maranhão were investigated. Two field trips were conducted, one at the beginning of the rainy season and another during the dry season. In each area, two plots (125 m2) equidistant 100 m apart from each other were surveyed. In these areas, standing dead tree trunks and dead branches still attached to the mother plant that were above the tideline, were examined. On these same occasions, samples of the aerial litter and from the cortex of living trees (Rhizophora) were collected for the preparation of moist chambers cultures. Twenty-one specimens were obtained from field and moist chambers, belonging to 11 species, distributed in nine genera and five families. Seven species are new records from Maranhão. There was a predominance of r-strategist (73%) over K-strategist (27%) species. Cribraria violacea, Comatricha tenerrima, Echinostelium minutum, and Fuligo septica are new worldwide records from mangrove environments, and Oligonema flavidum is reported for the first time from Brazil.

Introduction: little is known about the biodiversity of the genus Culicoides and the possible presence of vector species in Ceará State, Brazil. Objective: to improve the knowledge about the biodiversity and possible vectors presence in northeastern Brazil. Methods: with CDC light traps we surveyed Culicoides species in 18 municipalities from six mesoregions of Ceará State. Results: we collected 1 453 specimens (12 species). Culicoides guyanensis was the most abundant species, with 75,84% of the collected specimens. Culicoides venezuelensis is well distributed and is found in five Mesoregions. We recorded five species for the first time from Ceará State and seven from the surveyed municipalities; the presence of species with sanitary importance is discussed. Conclusion: with the addition of new species records, there are now 12 species known from Ceará State. The presence of species with medical and/or veterinary importance in the studied Mesoregions is indicative of the need of epidemiological surveillance in this state.

Potimirim potimirim (Müller, 1881), a species of coastal freshwater shrimp, is recorded for the first time from the state of Rio Grande do Norte, northeastern of Brazil, where it was collected in a small tributary of the Potengi River. This record extends the distribution of this species about 220 km north along Brazilian coast. New records, such as this, reinforce the need for greater research efforts in the northeastern freshwater ecosystems of Brazil to provide better understand the region’s biodiversity and establish better parameters for conservation actions.
