Morphology and Ontogeny of Histiostomatid Mites (Acari: Astigmata) associated with Cattle Dung in the Netherlands Naturalis
Bongers, M.G.H.; Oconnor, B.M.; Lukoschus, F.S..
Collections of histiostomatid mites from cattle dung and/or dung inhabiting insects from various localities in the Netherlands yielded 5 species which were cultured in the laboratory to obtain all ontogenetic stages. Descriptions are given for all stages in the life-cycles of Histiostoma brevimanus and Myianoetus simplex, species previously known only from deutonymphs, and Aphodanoetus teinophallus, gen. nov., spec. nov. A neotype is designated for H. brevimanus. Ontogenetic character transformations are described for two other species, Histiostoma phyllophorum and Rhopalanoetus fimetarius, species in which only deutonymphs and adults were previously described.

The wormsnakes (family Typhlopidae) of the Neotropics, exclusive of the Antilles Naturalis
Dixon, J.R.; Hendricks, F.S..
The systematic arrangement of the worm snakes (Typhlops) from the continental western hemisphere is presented. Allocations of many names historically assigned to Central and South American Typhlops are clarified. The continental Typhlops include nine species, two of which are described as new. The intraspecific variation of all species is explored within the limitations of known specimens. Three major radiations of New World Typhlops are postulated to account for the radiations of the present species groups.

Notes on the herpetofauna of Surinam : VI. Resurrection of Hyla ornatissima Noble (Amphibia, Hylidae) and remarks on related species of green tree frogs from the Guiana area Naturalis
Hoogmoed, M.S..
In the present paper Hyla ornatissima Noble is removed from the synonymy of Hyla granosa Boulenger, and resurrected as a separate species on the basis of morphological, ecological and acoustical differences. Another relative of this group occurring in Guiana is Hyla sibleszi Rivero. Because of its superficial resemblance with these frogs Hyla punctata (Schneider), of another species-group, is also treated. All four species are extensively described, data on life history and distribution are given. H. sibleszi, so far only known from the type material and some associated specimens, is reported from several new localities in Venezuela and Guyana. It is suggested that the function of the intricate dorsal pattern of H. ornatissima serves to protect the animal...
