The taxonomic status of 35 nominal species of Geometroidea from Cuba described by Herrich-Schäffer is discussed. Type material of 33 nominal species preserved in Coll. Gundlach, Instituto de Ecología y Sistemática, Havana, is evaluated. Thirty four species names are recognized, 11 species names are synonymized, six new combinations, six reinstated synonymies and four species recalled from synonymy are established, and one new species is proposed.

Seven nests of T. fuscus Emery, 1834 have been studied for their structure. These nests, which opened at the soil surface, had two to four chambers located one above the other. Externally all of these nests presented a heap of brownish-yellow debris that was constituted basically by remains of vegetable material. The total nest population was, on average, 1,048 individuais. The diel pattern of foraging of this species was studied for four consecuti ve months on two nests. This activity occurred predominantly in the night period, and the workers transported, mainly, dry vegetation to the nest.

Hawkmoths (Sphingidae) are among the major pollinators in tropical communities. Here the first survey of sphingids and related plants in Northeastern Brazil is presented. The sphingids were surveyed from March 1999 through April 2000 at the Reserva Biológica Guaribas, Mamanguape, Paraíba State. On black and mix light traps, 136 hawkmoths from 24 species were captured. Individuais of Erinnyis ello (Linnaeus, 1758), Isognathus menechus (Boisduval, 1875) and Xylophanes tersa (Linnaeus, 1771) represented 58% of the samples. One half of the recorded species show wide distribution in the Neotropics. Three species were registered for more than six months. Most of the species were found only in the dry or wet season. Pollen from 34 plant species were recorded by pollen analysis of sphingid mouth parts. Hancornia speciosa (Apocynaceae) and Guettarda platipoda (Rubiaceae) were the most important food plants. Both are characteristic elements of the Tabuleiro Nordestino and present typically sphingophilous flowers. More than one half of the sphingids presented pollen from only one or two species of plants. By transporting large quantities of pollen of a few species, hawkmoths seem to be the main pollinators of nocturnal flowers in the Tabuleiro Paraibano.

The ichneumofauna of Capão da Imbuia was studied during three years of capture, using Malaise traps. 114,469 specimens were captured, of which 3,603 belong to 20 subfamilies of ichneumonids. Pimplinae and Poemeniinae in the wood contains 14 genera and 48 species. In the first sample (1978-1979), 23 species were captured; in the second (1985-1986), 21 species were obtained, 13 of which had been previously captured, with an addition of eight species. And in the last sample (1995-1996), 39 species were obtained, of which 17 had not previously been captured. The dominant species, considering the number of individuals, were: Pimpla semirufa Brullé, 1846, Pimpla caerulea Brullé, 1846, Neotheronia aff. hespenheidei, Pimpla golbachi (Porter, 1970), Pimpla sumichrasti Cresson, 1874, Flacopimpla sulina Graf & Kumagai, 1997 and Pimpla tomyris Schrottky, 1902.

Ovigerous females of Arenaeus cribrarius were collected at Ubatuba, São Paulo, and maintaining in aquaria under controlled temperature (25±1ºC), salinity (35±1‰) and photoperiod (12:12). A small sample of eggs was collected for each 24h, for morphological description, chromatic changes and biometric analysis throughout the embryonic development. Eight egg stages were photographed and had their small and large diameters measured under a microscope provided with camera lucida. The egg's shape was low elliptical during all the embryogenesis and showed size increase (24.4%) and volume (91.1 %), when the last stage were compared with the first one. According to mean egg diameter and volume, the eggs should be pooled in three different groups (1-3; 4-6; 7-8) corresponding to initial, intermediate and final stages. The attained results were compared with the literature which emphasizing the species of Portunidae's family.

A really beautiful Euglossinae bee, Euglosssa (Euglossella) perpulchra sp. n., is decribed from Pernambuco, Igarassu, Brazil. It can be recognized by the following characters: head and thorax bronzeous green covered with fulvous pubescence, and abdomen bluish with white marginal bands narrowed progressively from second to sixth tergum; wings slightly fulvous, stigma and wing venation light fulvous. It is closely related to E. decorata Smith, 1874 and E. singularis Mocsáry, 1899.

Emas National Park is a very importam Conservation Unit in the Cerrado Biome. Nevertheless the fauna of this region is still poorly known. In this study, a revised list of the mammal fauna of the Emas National Park with comments about the composition and the number of species surveyed is presented. Eighty six species of mammals were recorded in the Park and neighboring area, including several rare and threatened species, like the bush dog (Speothos venaticus (Lund, 1842)), Marsh deer (Blastocerus dichotomus (Illiger, 1815)) and others. The giant rat (Kunsia tomentosus (Lichtenstein, 1830)) was recorded for the first time in a conservation unit. On the other hand, species usually very common in the Cerrado biome, don't occur in Emas National Park: the brazilian rabbit (Sylvilagus brasiliensis (Linnaeus, 1758)), marmosets (Callithrix spp.), and the punaré (Thrichomys apereoides (Lund, 1841)).

Stellifer stellifer (Bloch, 1790) is one among the most abundant ictiofauna species which are caught by sea-bob-shrimp's artisanal fishery in Armação do Itapocoroy. Aiming to analyze its population structure, a total of 1459 specimens were collected from July/1996 to August/1997. Stellifer stellifer presented lengths varying between 3,7 and 17,7 cm, macroscopic sex differentiation started from 6,0cm, with a higher frequency of females (sex ratio = 1:3,2). The relationship between length and weight was Wt = 0,0073Lt3,1415. First maturation size was determined for females (7,5 cm) and males (8,1 cm). The fishery acts in a similar way on juveniles and adults. Stellifer stellifer presented two spawning seasons, one in spring and another in autumn.

The bivalve family Isognomonidae is represented in the Western Atlantic by the living genera Crenatula Lamarck, 1804 and Isognomon Solander, 1786. I. alatus (Gmelin, 1791) and I. radiatus (Anton, 1839) are the only Isognomonidae referred to the Brazilian malacofauna. The present work refers to the first record and geographic distribution of I. bicolor along the Brazilian littoral, and presents a re-description of the species based on shell characters, which include those of the prodissoconch. The occurrence of I. alatus and I. radiatus along the Brazilian littoral could not be confirmed, despite the intensive search for these Isognomonidae from Rio Grande do Norte through Rio Grande do Sul.

Specimens of Mymarommatidae (Hymenoptera) were collected in São Paulo and Espirito Santo states in areas with cultivation of Eucalyptus L'Herit. This is the first record to this family from Brazil

A study on lhe geographical distribution of Callistomys pictus (Pictet, 1843) based on specimens conserved in museums, bibliography informations, and field observations is presented. The species is endemic to the Atlantic forest of the State of Bahia, Brazil. The destruction of the forests for pasture represents a serious threat to the survival of C. pictus and other species in southern Bahia.

Dicranthidium aliceae sp. nov. from Santana do Riacho. Minas Gerais and Dicranthidium seabrai sp. nov. from Lençois, Bahia are described. A new key to the species of the genus is provided.

The bivalves collected in the Western Antarctic and Subantarctic waters by scientists of the Instituto Oceanográfico - USP during the Scientific Brazilian Expeditions to Antarctical-IX are characterised through its conchiliological features, illustrated and their occurrence plotted in maps. A species of bivalve collected by scuba divers of the IO-USP on the Napier Rock, Admiralty Bay, King George Island during the Expeditions XV and XVI is also considered in this work. The material identified is representative of 25 species distributed among three families and four genera of Protobranchia, three farnilies and five genera of Pteriornorpha, five families and six genera of Heterodonta, and four families and four genera of Anomalo desmata. The main scope of this work is to provide searchers dealing with macrobenthic fauna with an ease identification guide to the bivalved molluscs of the sampled region.

The last instar larva of Microstigmus nigrophthalmus Melo, 1992 is described. It markedly differs from that of M. comes Krombein, 1967 the only other species in the genus whose mature larva have been described, for features as follows: presence of spinnerets; setae on the labrum, maxillae and labium; mandibles with tridentate apex and a bidentate lateral projection; lack of the conical supranal processo Notes on habitat, structure, and content of nests are also presented.

Populations of Ludwigia elegans (Carnb.) Hara were examined in Aluminio (600m) and Campos do Jordão (1520m), in the State of São Paulo. Flowers of both populations are self-incompatible and dependent on bees for pollination. Flowers of Ludwigia elegans at the Aluminio site were visited by about 30 different species of bees, and those at Campos do Jordão by 10. These results can be related to climatic differences at the two sites, especially temperature, due to their difference in altitude. Inspite of the difference in the absolute number of bee species seen at each site, Tetraglossula anthracina (Michener, 1989) (Colletidae) can be considered a specialized and efficient pollinator in both areas, since it visited these flowers frequently and showed many morphological and behavioral adaptations for pollen and nectar collection.

This study was carried out to investigate the reproductive aspects of the flying fish, Hirundichthys affinis Günther, 1866 considering their importance in the fish production of the Rio Grande do Norte State, Brazil. Fish samples were collected from the Municipality of Caiçara do Norte, northern coast of the state, during the period of April, 1999 to April, 2000. The fish were measured, weighed, dissected and the gonads were examined to separate the sex and to determine the stage of maturation. Histological studies were done for microscopic characterization of the gonads. The results indicated that H. affinis had a sexual proportion of 1:1; condition factor was inversely related to the gonadosomatic index during the reproductive phase; and the highest for both sexes was registered during the breeding season. Males and females showed four devolopmental stages of the gonads: immature, initial maturation, mature and spent. Absolute fecundity varied from 4400 to 6400 oocytes, with a mean of 5400. The species presents total spawing and the spawing season occurred in the months of May and June. The rainy season preceeded the occurrence of breeding flying fishes in the coastal waters of Caiçara do Norte.

Both castes of Scaptotrigolia postica (Latreille, 1804) possess four ovarioles in each ovary. Queen and workers have the same ovarian development during the larvallife, but in lhe late larval stage the queen ovary beco me larger. During pupation a higher rate of cell division is observed in queen ovarioles and a higher rale of cell death in workers. Newly emerged workers have short ovarioles with differenriatcd germarium and vitellarium while queens have very long ovarioles with only germarium. Caste deterrnination in rhis species of bee is trophic, but lhe food does not differ in quality, only in quantiry. The food differences only beco me effecri ve by the end of larval stage when the queen larvae have lhe opportunity of eat more. In this way lhe ovary differentiation, between workers and queens. In this species, only occurs frorn lhe end of larval stage, mainly during pupation. Although the ovaries of workers are smaller, they are precocious in relation to queens, since nurse workers, 5 10 20 days, old may lay eggs. The eggs laid by the workers may be trophic or functional. These eggs may be distinguished by lhe aspect ofthe yolk. Older forager workers have degenerated ovaries.

A qualitative survey of benthic macrofauna was carried out in the Guaratuba Bay, Paraná,Brazil. Twenty nine stations were sampled from April to July, 1996, including sublitoral and intertidal zones resulting in a preliminary list with 69 taxa. From this total, only 31,9% (22 taxa) were previously registered to the area.
