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.

Zammara smaragdula walker, 1858 (hemiptera: Cicadidae): First record for Brazil

The present note reports the first record for Brazil of the cicada Zammara smaragdula Walker, 1858 (Hemiptera, Cicadidae, Zammarini). This new record brings the number of reported Cicadidae species for Brazil to 153, including three species in the genus Zammara. © 2011 Check List and Authors.

First record in midwestern region of the state of são paulo, brazil of typhlops brongersmianus vanzolini, 1976 (squamata: Typhlopidae)

In this study we report on two new records of the blindsnake Typhlops brongersmianus for the municipality of Bauru, midwestern region of the state of São Paulo, Brazil. These records expand the geographic distribution currently known for this species in the state and contribute to the knowledge of snakes in southeastern Brazil. © 2011 Check List and Authors.

Endlicheria lhotzkyi is the first time recorded for the Brazilian state of Mato Grosso do Sul, collected in the municipal district of Sonora, north of the state. Taxonomic comments and an identification key of Endlicheria species from Mato Grosso do Sul is presented. © 2012 Check List and Authors.

First record of leucospis signifera bouček, 1974 (Insecta: Hymenoptera: Leucospidae) in the São Paulo State, Brazil

The present note extends the geographic range of Leucospis signifera Bouček, 1974 farther to the Northeast, reaching the State of São Paulo, based on the examination of four females collected at Jataí Ecological Station, municipality of Luiz Antônio, São Paulo State, Brazil. The present finding indicates that L. signifera is associated with dry ecosystems, at least in part of its geographic distribution. © 2012 Check List and Authors.

First record of chilodonella hexasticha (ciliophora: Chilodonellidae) in brazilian cultured fish: A morphological and pathological assessment

Chilodonelids are small ciliated protozoans found worldwide and can be dangerous in culture conditions. This study presents morphometric data on the ciliate Chilodonella that is found in cultured Nile tilapia (Oreochromis niloticus), native bait fish tuvira (Gymnotus aff. inaequilabiatus) and native pacu (Piaractus mesopotamicus) and includes a histopathological assessment of the changes that occur in the pacu. For parasitic diagnosis, skin and gill samples were scraped onto slides, dried at room temperature, stained with Giemsa or impregnated with silver nitrate, and the measurements were obtained from photomicrographs. In the diseased pacu, the first gill arch was collected and fixed in a 10% buffered formalin solution for histopathological analysis. Parasite specimens from the different collection sites were identified morphologically as C. hexasticha Kiernik (1909). Diseased fish exhibited depigmentation, skin ulceration, scale loss, excessive mucus production and gill lesions. Histopathological analysis of pacu gills displayed epithelial proliferation with mononuclear inflammatory infiltrate, hemorrhages, and scattering necrosis. In Brazilian-farmed fish this is the first record of C. hexasticha, which has great pathogenic potential in cultured freshwater species. In addition, two new hosts are presented. © 2012 Elsevier B.V.

First record of Austroleon dispar Banks, 1909 (Neuroptera: Myrmeleontidae) from Brazil

The present note extends the geographic range of Austroleon dispar Banks, 1909 to Brazil based on the examination of three females and one male collected in the Estação Ecológica Jataí, Luiz Antônio, São Paulo. The present finding indicates that A. dispar is associated with dry ecosystems, at least in part of its geographic distribution. © 2013 Check List and Authors.
