AbstractA new species of Nippostrongylinae (Nematoda: Heligmonellidae), Stilestrongylus rolandoi n. sp., is described from specimens collected from the small intestine of the rodent Euryoryzomys russatus in the Atlantic Forest (Santo Amaro da Imperatriz, Santa Catarina state, southern Brazil). The genus Stilestrongylus includes 23 species, which parasitize rodents occurring in the Neotropical region. Stilestrongylus aureus (Durette-Desset & Sutton, 1985) from Argentina, S. azarai (Durette-Desset & Sutton, 1985) from Argentina, S. flavescens (Sutton & Durette-Desset, 1991) from Uruguay, S. franciscanus (Digiani & Durette-Desset, 2002) from Argentina, S. gracielae (Digiani & Durette-Desset, 2006) from Argentina, and S. oryzomysi (Sutton & Durette-Desset, 1991) from Argentina are closely related to Stilestrongylus rolandoi n. sp., all having caudal bursa patterns of types 1–4 in one of the lobes. Stilestrongylus rolandoi n. sp. is distinguished from the aforementioned species by its ray 6 being short in relation to rays 4 and 5, which are long and robust, and by having caudal bursa patterns of types 1–4 in both lobes. The new species has 27 ridges in the mid-body in males, and 24 in females, and has one of the highest ratios of spicule length to body length (21−33%) in this genus.

Abstract A new species of Trichostrongyloidea (Nematoda: Heligmonellidae), Hassalstrongylus lauroi n. sp., is described from specimens collected from the small intestine of the rodent Hylaeamys seuanezi in the Atlantic Forest of northeastern Brazil (Igrapiúna, state of Bahia). The genus Hassalstrongylus includes 17 species, which parasitize rodents occurring in the Neotropical and Nearctic regions. It differs from the genus Stilestrongylus through its smaller number of ridges in the synlophe and through the size of the genital cone. The main taxonomic characteristics of this new species are the subsymmetrical caudal bursa of type 2-2-1, ray 8 branching out at the base of the dorsal trunk, right lobe smaller than the left, and rays 4 and 5 of robust nature. In addition, the ornamental ray 5 and the robustness of ray 4 on the male caudal bursa, along with the modification of the ridges of the posterior end of the female, allow us to consider the specimens found to be a new species.

Here we describe a new species of Prosopanche from southern Brazil. This is the first report of Prosopanche in Santa Catarina state and for the Atlantic Forest region. We present field photographs, illustrations, ecologic and conservation comments on the new species. We contrast the morphology of the new species with the other Prosopanche species that occur in Brazil, P. bonacinai and P. caatinguicola. The new species is morphologically similar to P. bonacinai, which has anthers composed by 20–30 thecae, synandrium 15–25 × 6–8 mm and tepals 35–55 × 9–20 mm vs. anthers composed by 3–4 thecae, synandrium 5–6 × 3–4 mm and tepals 15–20 × 5–8 mm in P. demogorgoni.

Myrceugenia joinvillensis, a new species from the Brazilian Atlantic Forest is described and compared with related species. This taxon seems to be restricted to the Serra do Mar range in the Southern Brazilian state of Santa Catarina in the municipalities of Joinville and Schroeder. Additionally, there are provided information on its phenology, distribution and conservation status.

Valeriana iganciana, an endemic species from the Serra do Tabuleiro highlands of Santa Catarina state, southern Brazil, is described and illustrated. The new species shares morphological affinities with V. ulei, from which it is distinguished mainly by leaves with entire margin, by the cymose architecture of the inflorescence and by the triquetrous and elliptical fruits with annular to dentate calyx.

A New Species

A new species of Paratelmatobius is described from the Brazilian Atlantic Forest in the state of Paraná in southern Brazil. Adults, tadpoles, and vocalizations are described. Morphological traits and phylogenetic analysis place the new species within the P. cardosoi group. The new species can be readily distinguished from its congeners by its advertisement call being composed of two note types and comprised of a series of 2–4 notes. The new species is classified as an explosive breeder, having reproductive activity strongly associated with heavy rainfall. This discovery highlights the importance of intensifying survey efforts in the Atlantic Forest, a domain with high levels of species richness and endemism.

ABSTRACT A new species of Characidium is described based on specimens obtained from the highland streams of the Serra do Mar, Atlantic Forest Biome, in Paraná State, Southern Brazil. The new species is possibly a member member of the C. lauroi group, which is diagnosed by having the isthmus unscaled, bars poorly marked, and spots on sides of body, and is composed by four additional species: C. japuhybense ; C. lauroi ; C. oiticicai ; and C. schubarti . The new species differs from its congeners with naked isthmus, except C. helmeri , by having 15-18 principal caudal-fin rays; and 10-12 pectoral-fin rays; and from C. helmeri , by having a slender body, tip of pectoral fin not reaching origin of pelvic fin, tip of pelvic fin not reaching beyond anus, supraorbital present and well developed, and by lacking vertically elongated dashes on sides of body. The new species is known from tributaries of the rio Jordão, in the rio Iguaçu Basin, and rio Taquari, a tributary of the rio Ribeira de Iguape coastal drainage.
