Poisoning due to Philodryas olfersii (Lichtenstein, 1823) attended at Restauração Hospital in Recife, State of Pernambuco, Brazil: case report

Few papers have been published on snake bites caused by Philodryas olfersii. We report here the first case identified at the Centro de Assistência Toxicológica do Hospital da Restauração, Recife, State of Pernambuco. This case was described based on medical protocols, interviewing the patient and identifying the animal that caused the bite. The patient presented pain, heat, erythema, edema and ecchymosis, without other laboratory abnormalities or coagulation disorders. The treatment consisted of administration of eight ampoules of antibothropic serum, and post-administration allergenic reactions were observed. The importance of bites by opistoglyph snakes needs to be reconsidered in research and at specialized treatment centers.

Predação oportunista de Artibeus planirostris (Spix, 1823) e Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) por marsupiais e anuro na APA do Rio Curiaú, Amapá, Brasil

Durante estudos com morcegos em floresta de várzea na APA do Rio Curiaú, Amapá, Brasil, observamos três casos de predações oportunistas de morcegos frugívoros capturados em redes de neblina. Duas destas predações ocorreram por marsupiais e uma por anuro. Artibeus planirostris (Spix, 1823) (Chiroptera, Phyllostomidae) foi predado por Didelphis marsupialis Linnaeus, 1758 e Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae). Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) foi predado por Leptodactylus pentadactylus (Laurenti, 1768) (Anura, Leptodactylidae). A vocalização dos morcegos provavelmente atraiu os marsupiais para a rede, onde estes os predaram aproveitando que estavam presos. Este tipo de interação pode ocorrer naturalmente, no entanto, com maior dificuldade de registro.

Drosophilidae (Diptera) associated to fungi: differential use of resources in anthropic and Atlantic Rain Forest areas

This study investigates the Drosophilidae species associated to fruiting bodies of fungi in forested and anthropized environments of the Atlantic Rain Forest Biome, in south and southeastern Brazil. We collected samples of imagoes flying over and emerging from fruiting bodies of species of five fungi families, in six collection sites. We obtained 18 samples, from which emerged 910 drosophilids of 31 species from the genera Drosophila Fallen, 1823, Hirtodrosophila Duda, 1923, Leucophenga Mik, 1886, Mycodrosophila Oldenberg, 1914, Scaptomyza Hardy, 1849, Zaprionus Coquillett, 1901 and Zygothrica Wiedemann, 1830. The Drosophila species collected on fungi, as well as Zaprionus indianus Gupta, 1970, had previously been recorded colonizing fruits, demonstrating their versatility in resource use. Most of these species belong to the immigrans-tripunctata radiation of Drosophila. Our records expands the mycophagous habit (feeding or breeding on fungi) to almost all species groups of this radiation in the Neotropical region, even those supposed to be exclusively frugivorous. Assemblages associated to fungi of forested areas were more heterogeneous in terms of species composition, while those associated to fungi of anthropized areas were more homogeneous. The drosophilids from anthropized areas were also more versatile in resource use.

On Pomacea sordida (Swainson, 1823) (Prosobranchia, Ampullariidae)

A description of Pomacea sordida (Swainson, 1823) collected in Caxias and Nova Iguaçu, state of Rio de Janeiro, is presented. The shell is globose, heavy, whith greenish or horn-colored periostracum and dark spinal bands; apex subelevated, 4-5 moderately shoudered whorls, increasing rather rapidly and separated by deep suture. Aperture large, moderately round, yellowish or violaceous; lip thick and sometimes dark brown; umbilicus large and deep; operculum corneous and heavy, entirely closing the aperture. Ratios: shell width/shell length = 0.81-0.91 (mean 0.86); aperture length/shell length = 0.66-0.75 (mean 0.70). Testis, spermiduct and penis pouch as in Pomacea lineata (Spix, 1827). Seminal vesicle whitish and bean-shaped. Prostate cylindric and narrow, cream in coloar as the testis. Penis whiplike whith a closed circular spermiduct. Penial sheath elongated and tapered, with its distal tip turned to the right; outer basal gland situated on the left; inner median gland rounded; apical gland elongated and wrinkled. Ovary composed of branched whitish tubules lying superficially on the digestive gland; oviduct and seminal receptacle as in P. lineata; albumen gland yellowish - orange. Vestigial male copulatory apparatus (penis and its sheath) present in all females examined.

On Dichelyne (Cucullanellus) elongatus (Tornquist, 1931) Petter, 1974: South American correlated species (Nematoda, Cucullanidae) and some other helminths of micropogonias furnieri (Desmarest, 1823) (Pisces, Sciaenidae)

Dichelyne (Cucullanellus) elongatus (Tomquist, 1931) Petter, 1974, from Venezuela, of which D.(C.) amaurincai (Freitas, Vicente & Ibáñez, 1969) Petter, 1974 is proposed as a junior synonym, is redescribed and comments on the present status of the remaining species under the group, namely D.(C.) dichelyneformes (Szidat, 1950) Petter, 1974, D.(C.) rodriguesi (Pinto, Fábio & Noronha, 1970) Petter, 1974 and D.(C.) travassosi (Guimarães & Cristofaro, 1974), occuring in South America are made. Dollfusentis chandleri Golvan, 1969 (Acanthocephala, Illiosentidae), Poecilancistrium caryophyllum (Diesing, 1850)(Cestoidea, Otobothriidae) and Callitetrarhynchus gracilis (Rudolphi, 1819)(Cestoidea, Dasyrhynchidae) as well as larval forms of Echinocephalus sp. (Nematoda, Gnathostomatidae) and Contracaecum sp. (Nematoda, Anisakidae) are also reported.

Monogenea parasites of Micropogonias furnieri (Desmarest, 1823) (Pisces, Sciaenidae) from the littoral of Rio de Janeiro state, Brazil

From the gills of 100 Micropogonia furnieri (Desmarest, 1823) from Atlantic coast of Rio de Janeiro State, were recovered Macrovalvitrema sinaloense Caballero & Bravo-Hollis, 1955, Pterinotrematoides mexicanum Caballero & Bravo-Hollis, 1955, Rhamnocercus rhmnocercus Monaco, Wood & Mizelle, 1954 and Encotyllabe spari Yamaguti, 1934. M. furnieri represents a new host record for them and a new geographical dsitribution is referred for M. sinaloense, P. mexicanum and R. rhmnocercus.
