Abstract in English:Several families were added in the past in order to constitute the Xanthidae, but the boundaries between Xanthidae, Parthenopidae and Goneplacidae were diluted, and the classification of some genera doubtful. By this reason was made the analysis of a typical genus of each subfamily occurring in Brazil. 50 characters were selected and coded as (0) for absence and (1) for presence. The data matrix was analysed by computer programs NTSYS and NMIX. The phenetic analysis shows the Xanthidae as a good family, but the cladistic one (Wagner tree) split them in four families: Carpiliidae, Xanthidae (with the subfamilies Menippinae, Platyxanthinae, Xanthinae and Eucratopsinae), Eriphiidae and Pilumnidae (with the subfamilies Trapeziinae and Pilumninae). Redescriptions and identifications keys for the proposed families and subfamilies are presented.
Abstract in English:Several reports on puma (Puma concolor) have been made in the State of Santa Catarina, Southern Brazil, most of them in remnant original habitats above 800 meters. These records show a thight relationship between the puma with altitude and mainly with habitat quality. The eastern boundary of the puma range isset by the mountain chains of Serra do Mar and Serra Geral. The definite implementation of National Parks and Reserves, studies of movements, and polimorfism analyses are suggested, in order to provide protected habitats and assure the genetic flow amongst puma populations.
Abstract in English:Saranthidium marginatum, sp.n. from Brazil (Minas Gerais and Parana) and Argentina (Misiones) and Hypanthidium erythrogaster, sp.n. from Brazil (Bahia, Espirito Santo, Rio de Janeiro, Minas Gerais and Mato Grosso do Sul) are described.

Abstract in English:Linnavuori, 1959 described the genus and species Andanus bimaculatus based on four specimens collected in Peru, Madre de Díos. In examining the type-material, we found that it was formed by two species belonging to a different genus. The female specimen (alotype) and one of the two males paratypes, that Linnavuori used to dissect the genitalia, is here described as Perundanus raunoi, gen.n., sp.n. Fora better characterization of the genus Andanus Linnavuori and A. bimaculatus Linnavuori , both are redescribed.
Abstract in English:The structure of the spermatozoon of Mugil curema Valenciennes, 1836 was studied using scanning and transmission electron microscopy. The spermatic head is rounded and formed by the nucleus containing granular chromatin, firmly packed resulting in a mass extremely electron dense. The acrossome is absent. The midpiece is characterized by the presence of two centrioles, a plasmatic canal, very few vesicles, and several mitochondria (9-10) with aproximately 0.50µm in diameter. The head and the midpiece are aproximately 1.56µm in diameter. The flagellum conforms to the 9 + 0 flagellar pattern near the transition region in its midpiece and is 9 + 2 from there on up to the distal region of the axoneme. The electron density in the A tubules 1, 2, 5 and 6 shows the asymetry of this spermatozoa. Its spermatic cell differs ultrastructuraly from those of other Mugilidae species mainly because it has the highest number of mitochondria.
Abstract in English:Trichogenes longipinnis (Britski & Ortega, 1983) is a leather fish restricted to the rivers on the shore in the southeast of Brazil. In this work, the oesophagous structure is being showed. The oesophagous appears itself short, dorsally inclinated toward pericardium and ventrally covered by liver lobe. By electron microscopy we can observe a mucosa layer formed by stratified squamous epithelium and lamina propria with stratum compactum. The epithelium is composed by three types of cells: superficial squamous cells; mucous cells, similar to the globet cells and polyhedric cells. The stratification of this epithelium provides a complete basal layer of proliferation polyhedric cells. The cells in the intermediate region of the epithelium are also polyhedric. These cells are just bellow the superficial squamous cells and packed among mucous cells.
Abstract in English:The observations made about the stomach of Trichogenes longipinnis (Britski & Ortega, 1983) showed a rounded organ which has in its dorsal side an accessory structure - a cul de sac - that comunicates with it. The distal part of this dorsal accessory presents characteristic of an organ that exercise respiratory functions: reduction in the thickness of the mucosa and arrangement of an intrincate continuous capilar net in close contact with the superficial cells of the epithelium. In this portion there are no glands in the lamina propria. The epithelium shows a superficial squamous cels; they are very slim, and sometimes, with the capillary endothelium form a single barrier between the organ lumen and the blood. Polyhedric cells are also present in this epithelium; they are located under the squamous cells, sheltered between capillaries and basal cells.
Abstract in English:The Brachyura collected on the continental shelf of Northern and Northeastern Brazil understood between the latitudes 4º27'N and 3º43'S and the longitudes of 50º00'W-38º00'W, were represented by 133 species, 79 genera and 15 families. The studied material, belongs to the carcinological collection of the Department of Oceanography of University Federal of Pernambuco. The informations obtained in relation to the areas in which these species are found, were gathered from the carcinological files cited above and bibliographic rcferences published until 1991. The majority of the species (125) was found exclusively in the western Atlantic, except three Anfi-Atlantics, two Anfi-Americans, two Circuntropicals and one Indo-Pacific. With regards to the latitude, 11 species were gathered with southern limits in the studies area, 17 species with northern limits in the studied area, six species restricted to the studied area and 99 with northern and southern limits out of the studied area.
Abstract in English:The vocal repertoire of the Azure Jay Cyanocorax caeruleus (Vieillot, 1818) is approached from a quali-quantitative point of view. The qualitative analysis was carried out both in the field and in captivity: the quantitative analysis was made only in captivity. Social acoustic communication in the Azure Jay is achieved through the use of two types of call: basic and intermediate calls. Fourteen basic calls are identified and presented through sonograms: the sotto voce song (courtship call) is related only to courtship and the social call is interpreted as the song in the Azure Jay. The intermediate calls are recombinations of the basic calls uttered during an alteration in motivation level. Examples of them are presented through sonograms of vocalizations recorded during mobbing predators and intraspecific agonistic contexts. The social, social-alarm, contact, flight, proximity, threat and social identity calls were those most frequently uttered by daylight: the other calls represented around 15% of the total number of utterances. The hypothesis of the evolution in American Jays, which tends to simplification of vocal repertoire (HARDY, 1961; 1969), is analysed; C. caeruleus seems to have a small actively-used repertoire.
Abstract in English:Five species of calliphorid flies, Chrysomya megacephala (Fabricius, 1794), C. putoria (Wiedemann, 1830), C. albiceps (Wiedemann. 1819), Cochliomyia macellaria (Fabricius, 1775) and Phaenicia eximia (Wiedemann, 1819), were collected hourly belween 6:00 and 18:00h., during five consecutive days per month for 12 moths; using home-made traps baited with rotting bovine lung. The data were statisticaly analyzed with relation to precipitation, temperature, relative humidity and luminosity. The results indicate that precipitation must have acted upon the seasonal abundance of the species, and that these responded equally to temperature, relative humidity and luminosity, throughout the entire day, except for P. eximia, which exhibited greater sensibility to these factors, demonstrating greater activity during the morning hours. The geographic expansion of invader species, associated to the tolerance to climatic variations was briefily discussed.
Abstract in English:Two hundred and eighty eight bird species were registered in Santa Rita Farm, east of Paraná State in Brazil (28º18'S,49º48'W), from February 1990 to January 1991. Eighty four species were registered in all 12 months and eighty three were registered once during this period. October was the richest in number of species (220) and July was the poorest (137). The natural landscape of the Santa Rita farm is composed of open field with several patches of araucaria forest (from 10 to 40 ha) and some small areas of marshland. Two hundred and eight species occurred only in one of these habitats: 163 in the forest, 35 in the open field and 10 in the marshland. The others often occurred in both forest and open field; there is a gradient of occurrence between them. Columba speciosa Gmelin, 1789; C. maculosa Temminck, 1813; Dolichonyx oryzivorus (Linnaeus, 1758) and Sporophila melanogaster (Pelzeln, 1870) were new field registers in Parana State. Because of its great number of bird species (some endangered species) and its landscape, composed of well preserved habitats, Santa Rita farm is shown as a strategic area for conservation.

Abstract in English:Rock paintings of mammals have been studied in five of the 243 localities contained within the 270,000 km² Archeological Region of Central, Bahia. From features of external morphology, it was possible to recognize 11 mammals represented in the paintings: for five, to attribute the species; another five, the genera; and, for one, merely the family. This study aims to underline the importance of prehistoric man's contribution, by way of these rock paintings, to our knowledge of the mammals depicted, both taxonomically and in terms of their distribution within the bounds of the Project in the State of Bahia.
