1. Two new species and a new distributional record of Alterosa (Trichoptera: Philopotamidae) from southeastern Brazil
Abstract The genus Alterosa Blahnik (2005), with 39 extant species, is endemic to Atlantic Forest areas of southern and southeastern Brazil. Herein, we describe and illustrate two new species from Rio de Janeiro state, southeastern Brazil: Alterosa cornuta sp. nov., easily diagnosed by the horn-like intermediate appendages crossing each other, and A. araras

3. Grooming behaviors and fouling of the spider crab Libinia dubia (Decapoda: Epialtidae)
Abstract Body fouling has been reduced by grooming behaviors. In decapods, grooming has been focused on gills, sensory structures, and jointed appendages. In this study, grooming behaviors of the spider crab, Libinia dubia H. Milne-Edwards, 1834, were examined; this brachyuran crab decorates and camouflages body regions by attaching materials onto hooked set

4. Intraspecific variation in megalopae of Clibanarius antillensis (Anomura, Diogenidae) among western Atlantic populations
ABSTRACT The objective of this study was to describe the morphology of Clibanarius antillensis Stimpson, 1859 megalopae collected in the vicinity of Isla Sacrificios, Mexico, and compare it to previous descriptions originated from Brazilian and Panamanian specimens raised in laboratory conditions. We found four meristic differences between the Brazilian and

5. Taxonomic revision of the Neotropical Lauxaniidae genus Neopachycerina Malloch, 1933 (Diptera: Schizophora), with description of a new species
Abstract A systematic review of the Neotropical Lauxaniidae genus Neopachycerina Malloch, 1933 is presented. The genus is characterized mainly based on some features of the head, like the anterior pair of fronto-orbital setae conspicuously shorter than posterior one and rather close to them; face with a distinct elevation between antennal bases; antenna slig

7. Morphological Diversity of Springtails in Land Use Systems
ABSTRACT: Springtails (Collembola) are soil organisms with wide morphological diversity and are sensitive to alterations in the soil, regardless of whether they are human-caused or not. The aim of this study was to evaluate the influence of land use on the morphological diversity of springtails and verify their relationships with soil physical, chemical, and

ABSTRACT A survey of the invertebrate fauna of coral reef hard bottom communities in the shallow waters of Isla del Coco yielded a new species of mysid belonging to the genus Heteromysis S. I. Smith, 1873. Heteromysis (Olivemysis) cocoensis, n. sp. was collected from coral rubble at depths of 8 to 34 m. It differs from its congeners by having male pleopods 1

12. Populations of Flavalona setigera (Brehm, 1931) in Brazil belong to a new species: Flavalona asymmetrica (Cladocera: Chydoridae: Aloninae)
Abstract Flavalona asymmetrica sp. nov. belongs to the costata-clade. This species has two main head pores, a feature shared only with Flavalona setigera (Brehm, 1931). Morphological differences between them are related to main and lateral head pores, armature of scrapers on the second limb, and proportion of setae on the third and fourth limbs, number of de
