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.

First record of L-quebrachitol in Allophylus edulis (Sapindaceae)

Allophylus edulis, commonly called 'Chal chal', is a member of the Sapindaceae occurring in the Uruguayan and Brazilian native flora. During the phytochemical analysis of two Chal chal specimens from two welldifferentiated geographical zones (Assis, São Paulo, Brazil, and Santa Lucia, Canelones, Uruguay), considerable amounts of L-quebrachitol were isolated from both samples. The isolation was carried out from the ethanolic twig extracts obtained by maceration of both vegetal samples. White easily distinguishable crystals were mechanically separated, washed, and characterized by 1D and 2D NMR experiments and by MS data. Such techniques confirmed that the crystals isolated from sources collected in both countries resulted in the same compound, L-quebrachitol, a natural product not previously reported for this species and one that has been investigated as a sugar substitute for diabetics. Worthy of note, the content of L-quebrachitol in A. edulis may be the chemical basis to explain its ethnobotanical uses, since infusions of this plant are used to treat diabetes in the practice of local traditional medicine.

First record of infection by entomopathogenic nematodes of the grass bug Collaria scenica Stal (Hemiptera: Miridae).

NARANJO N, MONTERO DAV, SAENZ APONTE A. 2011. First record of infection by entomopathogenic nematodes of the grass bug Collaria scenica Stal (Hemiptera: Miridae). ENTOMOTROPICA 26(3): 117-125. The study was aimed to test the pathogenicity of Steinernema sp. and Heterorhabditis sp. in Collaria scenica. The effect of different concentrations of infective juveniles (IJ) were tested on nymphs and adults of C. scenica. For this purpose, the bugs were inoculated with 5 000 JI of each nematode species in a factorial design (3x2), and seven concentrations were tested in a JI factorial design (7x2x2). The bugs showed 100% mortality and symptoms of pathogenicity. Infection was found with both species of nematodes and penetration was assumed to be through the spiracles and anus. A higher capacity of pathogenicity was observed with Steinernema sp. Based on the results Heterorhabditis sp. and Steinernema sp. could constitute an efficient tool to control populations of C. scenica in pastures.

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.

Amphibia, Anura, Centrolenidae, Hyalinobatrachium carlesvilai Castroviejo-Fisher, Padial, Chaparro, Aguayo and de la Riva, 2009: First country record, Brazil

We present the first Brazilian record of the recently-described glassfrog Hyalinobatrachium carlesvilai Castroviejo-Fisher, Padial, Chaparro, Aguayo and de la Riva, 2009. This species, previously known in Peru and Bolivia, was collected at two localities at the municipality of Aripuanã, northern state of Mato Grosso, Brazil. © 2010 Check List and Authors.
