This research presents a detailed study of the morphology of the head of adult in both sexes of the south Brazilian species of the Morphinae subfamily (Lepidoptera, Nymphalidae), as mentioned below: Morpho helenor violaceus Fruhstorfer, 1912; Iphimedeia hercules (Dalman, 1823); Iphixibia anaxibia (Esper, 1801); Cytheritis portis thamyris (Felder & Felder, 1867); Cytheritis aega (Huebner, 1822); Pessonia catenaria (Perry, 1811); Grasseia menelaus nestira (Huebner, 1821).

Based on the type specimen from the Zoologisches Museum der Humboldt Universitaet, Berlin, the systematic position of Exomalopsis latitarsis is discussed and a new combination is justified as Tapinorrhina latitarsis. A correct spelling Tapinorrhina is proposed for Tapinorhina Michener & Moure, 1957.

Arthurella Albuquerque, 1954 is redescribed and its systematic position is discussed. The puparium of A. nudiseta Albuquerque, 1954 is also redescribed and illustrated.

The Monticelliidae species, Nomimoscolex admonticellia (Woodland, 1934), comb.n., parasite of Pinirampus pirinampu (Spix, 1829) a freshwater siluriform fish, is redescribed. This species is the type of the genus Myzophorus Woodland, 1934. The authors discuss the validity of this genus and propose its suppression. Their species are transferred to Nomimoscolex (Zigobothriinae) whose diagnose is modified to include: N. admonticellia, comb.n., N. pirarara (Woodland, 1935), comb.n. and N. woodlandi (Rego, 1984), comb.n.

This paper presents a contribution to the study of the Crustacea, Decapoda of Brazil, including identification keys and informations on species range. Data related to the species of family Portunidae are published.

Scolotydaeus corticicola sp.n. is described, from the bark of an eucalyptus tree, from Piracicaba, São Paulo, Brazil.

Lissopedia, a new genus is proposed for Tetrapedia globulosa Friese, 1899, from Brazil and to include Tetrapedia flavopicta Cockerell, described from Yucatan, México. Three new species: Lissopedia ochronota from Albany, Jamaica, Lissopedia xanthina from Carmen (on the River Madre de Dios), Pando, Bolívia, and Lissopedia tristriata from Manaus, Amazonas, Brazil are described. The female of Lissopedia globulosa is described from Barreiras, Bahia, Brazil and thus a locality is given for this species. This genus seems to be confined to the Neotropical Region. Exomalopsini, Tapinotaspidini and Paratetrapediini are considered as tribes of Exomalopsinae.

Six new species from Campinaçu, Goiás (Hemiptera) are described: Notholopus (Notholopoides) niger, sp.n., T. tripallidus, sp.n., Prepops goianus, sp.n., P. semifemoratus, sp.n., Poeas clavata, sp.n. and Taedia goiana, sp.n.

The larva of Miathyria simplex (Rambur, 1842) is described, illustrated and compared to that of M. marcella (Selys, 1857). A key for identification of the South American Libellulidae larvae, wich show dorsal spines on abdominal segments III to VIII, is presented.

Gnathanthidium, gen.n. is proposed for two new species from South America, one from Brazil (Paraná, Santa Catarina and Rio Grande do Sul) and Argentina (Misiones) Gnathanthidium sakagamii, sp.n. and another from Argentina (Tucuman) Gnathanthidium ferrugineum, sp.n. The female of this Anthidiine bee nas peculiar mandibles without large teeth, only with two little ones on the apical margin.

This study was carried out in the region of Londrina, Paraná, Brazil in three different areas: a primary forest, a disturbed primary forest and an open area. Within 207 hours of capture, 990 individuals were collected, 939 of them being fruit-eating bats. Carollia perspicillata (Linnaeus, 1758), Sturnira lilium (Geoffroy, 1810), Platyrrhinus lineatus (Geoffroy, 1810) and Artibeus lituratus (Olfers, 1818) were the four most collected species in a total of 899 individuals. A. lituratus was found in greater number in all the areas, showing significant variation in relation to the size of the forests. The partition of food resources among the four most collected species was known through the analysis of their feces. The coexixtence of these species can be explained by their investing in different foods or their diverging time activity.

Two new species of Macrochelid acari Macrocheles novaodessensis, sp.n. and M. roquensis, sp.n. are described. These species inhabit cattle manure and were collected in several ranches in the state of São Paulo, Brazil.

Nests of the "Scaly-headed parrot" and "Illiger's macaw" - Pionus maximiliani (Kuhl, 1820) and Ara maracana (Vieillot, 1816) - found at the Ecological Station in Gália, São Paulo with clutches in 26-VII-90 and 20-IX-90, both containing four white rounded and at one end slightly pointed eggs, measuring 33.4x30.0mm and 33.0x28.0mm each respectively, are being reported on. The incubation in the "Scaly-headed parrot" lasted for 26 days, the stay of the young in the nest cavity for about 50 days and only one adult was seen incubating, while in "Illiger's or Blue-winged macaw" both parents used to stay in the nest.

A survey of nematode species parasizing Brazilian reptiles is presented, with data enough to provide their specific identification. The first section refers to the catalogation of the species, related to 127 superfamilies, 23 families, 55 genera and 121 species that are figured and included in measurement tables. The second section is concerned to the catalogue of host reptiles, with 16 families, and 90 species and their respective parasite nematodes. The identification of these helminths is achieved by means of keys to the superfamilies, families and genera. Specific determination is induced through the figures and tables as above mentioned.

Leidyula goodfriendi, sp.n. is described.

The species Phaleria testacea Say, 1824 (Coleoptera, Tenebrionidae) varies a lot in size, and its populations along the coast of Brazil, where it lives buried in sandy beaches, have temporal and geographical variation in density. In order to find out which factors were contributing to these variations, we sampled populations from three different areas in Rio de Janeiro, during summer and winter. Simultaneously, we made an analysis of the different substracts where the individuals were found, including their total fresh weight. The results show a significant difference in size of individuals between and within populations, when summer and winter were compared. There is also a positive association between the population density of P. testacea and the amount of "garbage" found at the study areas.

Thirty-three species of anuran amphibians and 22 species of reptiles were found in 9 days and nights of sampling in an unexplored region of Central Amazon. The community is characterized by typical lowland Amazonian species. The relatively short sampling time and high number of species caught indicates that this region probably has very high species richness.

The occurrence of synanthropic muscoids associated with the urban garbage in the town of Goiânia, Goiás, Brazil was investigated from March, 1987 to February, 1988. Flies were captured by entomological nets in four different sites: periodical food markets, popular markets, garbage containers and the municipal refuse dump. The following species were founded: Phaenicia eximia, P. sericata, P. cuprina, Chrysomya putoria. C. albiceps, C. megacephala, Musca domestica, Ophyra sp., Fannia sp. and several species of Sarcophagidae.
