A revision of Monimiaceae from the Southern limit of the Atlantic forest domain resulted in the discovery of a species heretofore undescribed. Mollinedia leucantha, a treelet endemic to the Atlantic coastal moist forest in southern Brazil, is described and illustrated. Morphologically the new species is most similar to Mollinedia schottiana, from which it is set apart by characteristics in the rhytidome, leaves, trichomes, flowers and fruitlets, as well as by distinct flowering times. Additionally, scanning electron microscopy (SEM) images of the flowers and a key to distinguish morphologically similar or related species in the subtropical Atlantic forest are presented. A preliminary extinction risk assessment is also provided for the new species.

Passiflora coelestis is morphologically and anatomically described from living material as a new species belonging to the section Dysosmia, supersection Stipulata and subgenus and genus Passiflora. The species occurs in Araucaria Moist Forest, a phytophysiognomy of the Atlantic Forest biome. The section has been characterized as one of the most taxonomically complex groups within Passiflora. Passiflora coelestis is related to species within the Dysosmioides group and is similar to P. campanulata, differing mainly in the stipules, petiole, bracts, and corona filaments. The new species is morphologically compared with taxa of the section; moreover, additional anatomic, palynological and molecular data are also discussed with regard to taxonomic classification.

Three New Species

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

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 Paracanthon Balthasar 1938 includes four nominal species of dung beetles occurring in the Atlantic Forest of northeastern, southeastern and southern Brazil, and Misiones, Argentina. Here we describe twelve new species of Paracanthon: P. arnaudi sp. n., P. belloi sp. n., P felipei sp. n., P genieri sp. n., P. grossiorum sp. n., P. laevinotus sp. n., P. lopesandradei sp. n., P. marinezae sp. n., P. millerorum sp. n., P.monteiroorum sp. n., P. muriloi sp. n., P. ocellatopunctatus sp. n. We propose P. pereirai d’Andretta & Martínez 1957 as a new junior subjective synonym of P. rosinae Balthasar 1942. In addition, we present new data on the morphology of the hindwings and male genitalia, and an identification key to the species of the genus. Paracanthon is restricted to the Atlantic domain, and we briefly discuss the possible processes that might have led to the diversification of the putative lineages recognized here.

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.

In the present study, we analyzed the taxonomy and ecology of fourteen species of Luticola registered in oligo- to hypereutrophic reservoirs of southeastern Brazil. Two new species were described using light and scanning electron microscopy. Luticola bartolomeii sp. nov. and Luticola iporangensis sp. nov. are distinguished from morphologically similar species by a combination of valve outline and dimensions. In addition, L. bartolomeii showed occluded isolated areolae that have a different shape and location, hitherto not observed in other Luticola species. We also compared the morphology of the new species with similar taxa and provided information on their ecological preferences. Luticola panamaensis is first recorded in Brazil, and another eight species are recorded for the first time for the state of São Paulo. This study expanded the distribution of species and added new information to the ecology of Luticola, as well as provided the first SEM images for some already known species. Information on the co-occurrence of other diatom species in the samples is also included.

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.
