Occurrence of infection by Platynosomum illiciens (Braun, 1901) in captive neotropical primates

Platynosomum illiciens (Trematoda, Plagiorchida) is a trematode parasite reported in felids and falconiforms. It was identified in the gall bladder of eight captive neotropical necropsied primates from the National Primate Center (CENP), Ananindeua, State of Para, Brazil. This is the first description of Platynosomum illiciens as a parasite of primates.

Endoparasites new to the Neotropical freshwater turtle, Mesoclemmys vanderhaegei (Bour 1973) (Testudines, Chelidae), from central Brazil.

Information on endoparasites infecting Neotropical turtles is scarce. The present paper reports the occurrence of endoparasites in three adult individuals of Vanderhaege's Toad-Headed Turtle (Mesoclemmys vanderhaegei). The records include an undescribed nematode species in the genus Spiroxys, not previously reported for the family Chelidae, and the first South American record of a monogenetic trematode of the genus Neopolystoma.

Hunting spiders of woodland fragments and agricultural habitats in the Atlantic rain forest region of Brazil

The hunting spider communities of the Dionycha clade were studied 1986 through 1988 in fragmented woodlands and secondary agricultural habitats of the Botucatu area in São Paulo state, Brazil. The original vegetation of mainly tropical Atlantic rain forest (Mata Atlantica) was cleared already 70 years ago. In a total sample of over 1000 adult spiders, 247 species belonging to 12 families Mere determined. A decreasing frequency and diversity of spiders rc as found if forest remnants were compared with sugar cane fields and cattle pasture. The specific composition of the spider fauna as surveyed in different habitats is discussed under ecological aspects and in relation to the history of land use.
