A new species of Triceratiaceae is described for estuarine environments of Southern Brazil. The valve of Triceratium moreirae sp. nov. is triangular with elevations bearing ocellus and a rimoportula in their basis. The valvar surface has robust pseudoloculi, circular to polygonal, each one confining a group of areolae arranged in a typical pattern. A central larger areola is surrounded by 5-8 smaller areolae, and they are poroidal with domed cribra. A septum emerges from the valvocopula, having the base reinforced by ribs and the margins folded to the innerside of the valve. The new species is compared to the closely related diatom Triceratium dubium, which has the same pattern of areolar disposition, formation of septum and pseudoloculi. The main diferences in relation to T. moreirae are: rimoportulae intercalated to ocelli and with a characteristic morphology (spinules on the edge of the external aperture), and more elongated elevations with a constriction. Some criteria used for the classification of categories into the Triceratiaceae are also discussed, and we propose that the type of areola (poroidal with cribra) be included in the circumscription of Triceratium.

A New Species

The classification of the superfamily Psylloidea is revised to incorporate findings from recent molecular studies, and to integrate a reassessment of monophyla primarily based on molecular data with morphological evidence and previous classifications. We incorporate a reinterpretation of relevant morphology in the light of the molecular findings and discuss conflicts with respect to different data sources and sampling strategies. Seven families are recognised of which four (Calophyidae, Carsidaridae, Mastigimatidae and Triozidae) are strongly supported, and three (Aphalaridae, Liviidae and Psyllidae) weakly or moderately supported. Although the revised classification is mostly similar to those recognised by recent authors, there are some notable differences, such as Diaphorina and Katacephala which are transferred from Liviidae to Psyllidae. Five new subfamilies and one new genus are described, and one secondary homonym is replaced by a new species name. A new or revised status is proposed for one family, four subfamilies, four tribes, seven subtribes and five genera. One tribe and eight genera / subgenera are synonymised, and 32 new and six revised species combinations are proposed. All recognised genera of Psylloidea (extant and fossil) are assigned to family level taxa, except for one which is considered a nomen dubium.

A New Species

A new species of Amplicaecum is described from the carpet snake (Morelia argus variegatus) in coastal Queensland. It differs from all previously described species in this genus in that its host is a pythonid snake. It is the largest species yet described, and the spicules are about 3 times as long as in any other species. The genus Amplicaecum is tentatively re-defined and a key is given to the differential features of the recognized species. The view is expressed that before classification of these and related ascaridoids can be adopted, further information is necessary, particularly on (1) the phylogenetic significance of differential features already in use, and (2) on the existence of other more significant differential features.

A New Species

A new species, Eucalyptus fusiformis Boland et Kleinig, from the north coast of New South Wales is described. Its taxonomic position is in E. subgenus Symphyomyrtus series Paniculatae following the informal classification of eucalypts proposed by Pryor and Johnson (1971). E. fusiformis is characterised by its flowers, fruits and adult leaves. In the bud the staminal filaments are fully inflected while the androecium has outer staminodes and the anthers are cuboid and adnate. The fruits are narrow, often truncate fusiform, tapering into long slender pedicels. The adult leaves are dull grey, concolorous and hypoamphistomatic. The species resembles the more numerous and often co-occurring ironbark E. siderophloia which has similar adult and seedling leaves. The volatile oils of both species are very similar. The ecology, distribution, taxonomic affinities and conservation status are discussed.

FEED FLAVOR OR STABLE ODOR IN MILK CAUSED BY AN ATYPICAL STRAIN OF AEROBACTER OXYTOCUM

A New Species

A cultural study was made of an organism of the Escherichia-Aërobacter group in connection with the production of an alleged feed flavor or stable odor in milk. A tentative classification of the organism as an atypical strain of Aërobacter oxytocum, (Migula) Bergey et al., is based on the sum of its characteristics. The suggestion is made that the organism may be defined as a new species within the genus Aërobacter, but until other characteristically identical strains have been isolated, this is merely tentative.

A New Species

A new species of Dolops is described from Lake Surprise, Tasmania, where it has been found on a galaxiid fish. Hitherto the genus has been known only from freshwater in S. America and Africa. Taxonomic errors involving an alleged Asiatic member of the genus are rectified and recent gross mistreatment of the classification of the Branchiura is discussed. The genus Dolops is re-defined. Evidence bearing on the history and dispersal of Dolops and other organisms is reviewed, particular attention being directed to the freshwater bivalve molluscs formerly assigned to the Mutelidae. While the African and S. American muteloids belong to closely related families of the Muteloidea, the Australasian forms formerly thought of as representatives of this group have no place in this superfamily. They, and certain S. American bivalves, however, show unambiguous trans-Antarctic affinities as they belong to a common family, the Hyriidae. Taking into account recent work, both geological and biological, and in spite of powerful voices raised in objection, the disjunct distribution of several groups of animals in the Southern Hemisphere seems to be most plausibly explained as a result of continental drift, though no dogmatic claims are made.
