Nidularia pulvinata (Schwein.) Fries (Gasteromycetes): a new record from Brazil

A survey of the gasteroid mycota from "cerrado" vegetation of the state of São Paulo, Brazil, revealed for the first time a rare species of nidulariaceous fungi, Nidularia pulvinata, growing on decaying wood of Syagrus flexuosa (Mart.) Beccari (Palmae). Descriptions of the macro and microscopic features of N. pulvinata, including taxonomic considerations, are given.

LAURENCIA MARILZAE (CERAMIALES, RHODOPHYTA) FROM THE MEXICAN CARIBBEAN: A NEW RECORD FOR THE TROPICAL WESTERN ATLANTIC

Laurencia marilzae Gil-Rodriguez, Senties & MT Fujii is recorded for the first time for the tropical western Atlantic Ocean, occurring in Isla Mujeres, Quintana Roo, Mexican Caribbean. The specimens were collected in November 2008 and June 2009, growing epilithically in the lower intertidal zone on moderately exposed rocky shores. This species is characterized by its distinctive yellow-orange color in the natural environment, four pericentral cells per vegetative axial segment, the presence of secondary pit-connections between adjacent cortical cells, which are markedly projecting at the apices, and by the presence of one ""corp en cerise"" per cell in all cells of the thallus: cortical, medullary, including pericentral and axial cells, and trichoblasts. Morphological similarities and molecular data support the determination of this material as L. marilzae. The present study expands the geographical distribution of L. marilzae to the Caribbean Sea in the tropical Western Atlantic Ocean.

Palisada flagellifera (Ceramiales, Rhodophyta) from the Canary Islands, Spain: a new record for the eastern Atlantic Ocean based on morphological and molecular evidence

Palisada flagellifera (Ceramiales, Rhodophyta) is recorded for the first time in the eastern Atlantic Ocean off Tenerife, La Gomera, La Palma and Fuerteventura, Canary Islands, Spain. The specimens were collected in 2006-2009 growing from the lower intertidal to subtidal zones to 2 m depth at sites exposed to wave action. The species possesses a palisade-like arrangement of cortical cells in cross section, lacks secondary pit connections between them, and has tetrasporangia produced by three fertile pericentral cells (the third and the fourth additional and the second that becomes fertile), and a right-angled arrangement of tetrasporangia. Gametangia were not observed. The phylogenetic relationships were inferred by analyses of the chloroplast-encoded rbcL gene sequences from 46 taxa. The Canarian and Brazilian P. flagellifera specimens formed a highly supported clade with a low level of genetic variation in the rbcL sequences (0.02-0.04%), confirming that they are the same taxonomic entity. This study expands the geographical distribution of P. flagellifera to the eastern Atlantic Ocean.

New record of Trichospilus diatraeae Margabandhu & Cherian, 1942 (Hymenoptera: Eulophidae) parasitizing Sarsina violascens (Herrich-Schaeffer, 1856) (Lepidoptera: Lymantriidae) in Brazil

This is the first report of Trichospilus diatracae (Hymenoptera: Eulophidae) found in the field, parasitizing pupae of the eucalyptus defoliating Sarsina violascens (Herrich-Schaeffer, 1856) (Lepidoptera: Lymantriidae) in Brazil. This offers a new perspectives for the use of this parasitoid in biological control programs against caterpillars of forestry importance.

New record of Haplometroides intercaecalis (Digenea, Plagiorchiidae) infecting a Brazilian snake

Phalotris matogrossensis (Serpentes, Colubridae) was reported as a new host for Haplometroides intercaecalis ( Digenea, Plagiorchiidae). The host snake was obtained from the municipality of Anastacio, state of Mato Grosso do Sul, Brazil. One specimen of H. intercaecalis was recovered from the esophagus of the host and identified by the intercecal position of the vitellaria in the pre-acetabular region. This paper describes the second report of the occurrence of this trematode in fossorial snakes of the genus Phalotris in the state of Mato Grosso do Sul, Brazil.

Three new species of Phytoseius Ribaga (Acari: Phytoseiidae), and a new record from Brazil

New record of Rhagomys rufescens (Thomas 1886) (Rodentia : Muridae : Sigmodontinae) in the Atlantic forest of southeastern Brazil

Rhagomys rufescens is a threatened Sigmodontinae rodent from the Atlantic forest of southeastern Brazil, known by a few specimens deposited in scientific collections. This work presents a new record of this species, collected in Parque Estadual da Serra do Mar-Nucleo Picinguaba (Ubatuba, SP) in April 2002, and some biological data. This finding reinforces the urgency of improving collecting efforts in Atlantic forest, in order to know and preserve its biodiversity.

Cytogenetics of three Brazilian Goniosoma species: A new record for diploid number in Laniatores (Opiliones, Gonyleptidae, Goniosomatinae)

Currently, 60 species of harvestmen have been karyotyped and all of these are from the Nearctic and Palearctic regions. This work is the first cytogenetic report of three gonyleptid species of the suborder Laniatores: Goniosoina aff. badiuln, G. proxiinuni and G. spelaeum of the Neotropical region, from the southeastern region of Brazil. Conventional Giemsa stain chromosome preparations were obtained from embryonic cells and adult male testes. Embryo mitotic plates of G. aff. badium and G. proximum indicated 88 chromosomes, and mitotic spermatogonial plates of G. spelaeum males revealed intra- and interindividual variation of chromosome number, ranging from 92-109 chromosomes. In the three analyzed species, the mitotic chromosomes were meta- or subinetacentric with no obvious sex chromosomes being identified during mitosis. Prophase I spermatocytes of G. spelaeum also revealed intra- and interindividual bivalent number variation and furthermore indicated the presence of multivalence. The karyotypes of these three Goniosoina species exhibited the largest chromosome pair with a negative heteropycnosis in the distal region of the shortest arrn chromosomes of G. spelaeum submitted to silver impregnation evidenced this negative heteropycnotic region as nucleolus organizer region (NOR). These results, when compared with cytogenetic data of other Laniatores species from the Palearctic region, indicated that a new record for diploid chromosome number probably characterize the genus Goniosoma in the Neotropical region.

Stoneflies (Plecoptera) from northern Goias State, central Brazil: new record of Kempnyia oliveirai (Perlidae) and a new species of Tupiperla (Gripopterygidae)

A new species of Tupiperla, T. jumirim, is described from Chapada dos Veadeiros, northern Goias State, Brazil. Kempnyia oliveirai is recorded from the same locality.

Bat community in a cave from eastern Brazil, including a new record of Lionycteris (Phyllostomidae, Glossophaginae)

A cave bat community from a semiarid region in eastern Brazil was studied during the dry season. A high diversity was observed, with thirteen species recorded. Except for Micronycteris minuta and Lionycteris spurrelli, these bats were also found in other Brazilian karstic areas. The commonest species were the hematophague Desmodus rotundus, the omnivore Carollia perspicillata, and the insectivore Natalus stramineus. The bats formed itinerant colonies, moving frequently inside the cave. L. spurrelli was previously known from Amazonia, usually associated with evergreen forests. The present record extends its range 1600 km to the south. A disjunct distribution explains some morphological differentiation between Amazonia and Olhos d'Agua cave populations. The latter may be a relict of former continuous forest vegetation, which has been fragmented after the climatic optimum. Dispersion through the Cerrado forest gallery is also possible.

New record for the army ant Labidus mars (Formicidae: Ecitoninae) in the Atlantic Rain Forest of São Paulo State, Brazil

The occurrence of the army ant Labidus mars in Mogi das Cruzes (SP, Brazil) is recorded and includes additional information about the area, diet and foraging schedule of this rare army ant. This species of Ecitoninae was collected from two mature fruits of the Syagrus romanzoffiana (Arecaceae) and were probably in the foraging phase.

Distribution and habitat use of Sordellina punctata (Serpentes, Colubridae), with a new record from State of São Paulo, Brazil

Sordellina punctata occurs throughout south and southeastern Brazil in the Atlantic Forest domain (states of São Paulo, Paraná and Santa Catarina). Records from the states of Rio de Janeiro and Mato Grosso do Sul are questionable. A new record from southwestern São Paulo extends its distribution west and northward, probably indicating a wider range in the past. Habitat use in S. punctata implies that it may be more associated with wetlands and other saturated areas than truly aquatics ones.

New record of Pelecitus sp (Nematoda, Onchocercidae) as a parasite of Athene cunicularia (Strigiformes, Strigidae) in southeastern Brazil

The aim of this study was to report the burrowing owl Athene cunicularia as a new host for the filarid nematode Pelecitus sp. in southeastern Brazil for the first time, as well as reporting the occurrence of this nematode species in the body cavity, near the cervical air sac and lung region. This study contributes towards knowledge of parasitism in Brazilian wild birds and an anatomical region of the host as an infection site for Pelecitus sp.
