Resumo:
Eryphus Perty, 1832 and Tacyba, a new genus of Heteropsini (Coleoptera, Cerambycidae). Some species, up to now, included in Callideriphus Blanchard, 1851 are rearranged in: a) those congeneric with Callideriphus grossipes Blanchard, 1851 and b) not congeneric. The first set of species will be treated in a future paper; the second one, on the other hand, is subdivided into Eryphus Perty, 1832 and Tacyba gen. nov. Eryphus Perty, 1832 (type species: Eryphus bipunctatus Perty, 1832), a valid genus, is redescribed and a key for the species is also provided. The following species are transferred to Eryphus: E. bivittatus (Melzer, 1934) comb. nov., E. carinatus (Zajciw, 1970) comb. nov., E. flavicollis (Fisher, 1938) comb. nov., E. laetus (Blanchard, 1851) comb. nov., E. marginatus (Zajciw, 1970) comb. nov., E. picticollis (Gounelle, 1911) comb. nov., E. transversalis (Fairmaire & Germain, 1864) comb. nov. New synonym proposed: Eryphus bipunctatus Perty, 1832 = Callideriphus atricollis Melzer, 1931. New taxa described: Eryphus tacuarembo sp. nov. (Uruguay, Tacuarembó), E. carioca sp. nov. (Brazil, Rio de Janeiro); Tacyba gen. nov. (type species: Callideriphus maculatus Cerda, 1988). Species transferred to Tacyba and synonyms: T. maculata (Cerda, 1988) comb. nov., T. tenuis (Blanchard, 1851) comb. nov. = Callideriphus testaceicornis Fairmaire & Germain, 1859 syn. nov. = Callideriphus clathratus Fairmaire & Germain, 1860 syn. nov. = Callideriphus niger Philippi & Philippi, 1864 syn. nov. Callideriphus flavicollis m. quadripunctatus Fuchs, 1961 and Callideriphus flavicollis m. reductus Fuchs, 1961, both names of infrasubspecific category (not available under the rules of ICZN), are herein treated as intraspecific variation of Eryphus picticollis (Gounelle, 1911) which occur in southern Brazil and Argentina.

The genus Callideriphus Blanchard, 1851 (Coleoptera, Cerambycidae, Heteropsini). The genus Callideriphus comprises only two species: C. grossipes Blanchard, 1851 (type species) and C. tucumanus sp. nov. (Argentina, Tucumán). The type locality of C. grossipes had been originally indicated as Chile, but it is supposedly considered erroneous. Its distribution, actually, extends from Southeastern Brazil up to Argentina, along the Atlantic Forest. This species is extremely variable in regard to its coloration and elytral punctation. Two subspecies are recognized: C. grossipes grossipes Blanchard, 1851 (BRAZIL: Minas Gerais, Espírito Santo, São Paulo, Paraná, Santa Catarina) and C. grossipes flavipennis Melzer, 1934 (BRAZIL: Santa Catarina, Rio Grande do Sul; ARGENTINA: Chaco, Entre Ríos, Buenos Aires). Four intermediate forms are recorded and commented. Redescription and a key to species are added. Nomenclatural changes: Callideriphus grossipes grossipes Blanchard, 1851 = C. grossipes var. brasliensis Melzer, 1923 syn. nov. = C. rubricollis Melzer, 1934 syn. nov.; Callideriphus grossipes flavipennis Melzer, 1934 stat nov. = C. signaticollis Melzer, 1934 syn. nov.

The genus Xylocopa Latreille in Rio Grande do Sul, Brazil (Hymenoptera, Anthophoridae). A survey of the genus Xylocopa Latreille, 1802 is given for Rio Grande do Sul, the southernmost State of Brazil. Data are based on several studies on the bee fauna of southern Brazil and on unpublished observations. A key is provided to the species (males and females) and information on distribution, nesting habits and relation to flowers. Rio Grande do Sul is strikingly rich in species of Xylocopa because of the diversity of habitats and its geographic position in the transition of tropical/subtropical to temperate climate. Nineteen species, classified into ten subgenera, have been recorded in Rio Grande do Sul. Here we maintain the subgenera Ioxylocopa, Megaxylocopa and Xylocospila, which were put into synonymy recently by Minckley (1998). The species are: Xylocopa (Dasyxylocopa) bimaculata Friese, 1903; Xylocopa (Ioxylocopa) chrysopoda Schrottky, 1902; Xylocopa (Megaxylocopa) frontalis (Olivier, 1789); Xylocopa (Nanoxylocopa) ciliata Burmeister, 1876; Xylocopa (Neoxylocopa) augusti Lepeletier, 1841; Xylocopa (N.) brasilianorum (Linnaeus, 1767); Xylocopa (N.) haematospila Moure, 1951; Xylocopa (N.) hirsutissima Maidl, 1912; Xylocopa (N.) nigrocincta Smith, 1854; Xylocopa (N.) ordinaria Smith, 1874; Xylocopa (N.) suspecta Moure & Camargo, 1988; Xylocopa (N.) tacanensis Moure, 1949; Xylocopa (Schonnherria) macrops Lepeletier, 1841; Xylocopa (S.) simillima Smith, 1854; Xylocopa (S.) splendidula Lepeletier, 1841; Xylocopa (S.) varians Smith, 1874; Xylocopa (Stenoxylocopa) artifex Smith, 1874; Xylocopa (Xylocopoda) elegans Hurd & Moure, 1963; Xylocopa (Xylocopsis) funesta Maidl, 1912; Xylocopa (Xylocospila) bambusae Schrottky, 1902.

This work, dedicated to the study of nesting habits of the species of the Neotropical genus Partamona Schwarz, is a sequence to the taxonomic revision recently published elsewhere. A total of 214 nests and nest aggregations of 18 species [Partamona epiphytophila Pedro & Camargo, 2003; P. testacea (Klug, 1807); P. mourei Camargo, 1980; P. vicina Camargo, 1980; P. auripennis Pedro & Camargo, 2003; P. combinata Pedro & Camargo, 2003; P. chapadicola Pedro & Camargo, 2003; P. nhambiquara Pedro & Camargo, 2003; P. ferreirai Pedro & Camargo, 2003; P. pearsoni (Schwarz, 1938); P. gregaria Pedro & Camargo, 2003; P. batesi Pedro & Camargo, 2003; P. ailyae Camargo, 1980; P. cupira (Smith, 1863); P. mulata Moure in Camargo, 1980; P. seridoensis Pedro & Camargo, 2003; P. criptica Pedro & Camargo, 2003; P. helleri (Friese, 1900)] were studied , including data about habitat, substrate, structural characteristics, construction materials and behavior. The descriptions of the nests are illustrated with 48 drawings. Partial data of the nests of P. bilineata (Say, 1837), P. xanthogastra Pedro & Camargo, 1997, P. orizabaensis (Strand, 1919), P. peckolti (Friese, 1901), P. aequatoriana Camargo, 1980, P. musarum (Cockerell, 1917) and P. rustica Pedro & Camargo, 2003 are also presented. Nests of P. grandipennis (Schwarz, 1951), P. yungarum Pedro & Camargo, 2003, P. subtilis Pedro & Camargo, 2003, P. vitae Pedro & Camargo, 2003, P. nigrior (Cockerell, 1925), P. sooretamae Pedro & Camargo, 2003 and P. littoralis Pedro & Camargo, 2003 are unknown. The species of Partamona build notable nest entrance structures, with special surfaces for incoming / exiting bees; some of them are extremely well-elaborated and ornamented, serving as flight orientation targets. All species endemic to western Ecuador to Mexico with known nesting habits (P. orizabaensis, P. peckolti, P. xanthogastra, P. bilineata, P. aequatoriana and P. musarum) build their nests in several substrates, non-associated with termitaria, such as cavities and crevices in walls, among roots of epiphytes and in bases of palm leaves, in abandoned bird nests, under bridges, and in other protected places, except P. peckolti that occasionally occupies termite nests. In South America, on the eastern side of the Andes, only P. epiphytophila and P. helleri nest among roots of epiphytes and other substrates, non-associated with termitaria. All other species studied (P. batesi, P. gregaria, P. pearsoni, P. ferreirai, P. chapadicola, P. nhambiquara, P. vicina, P. mourei, P. auripennis, P. combinata, P. cupira, P. mulata, P. ailyae, P. seridoensis, P. criptica and P. rustica) nest inside active termite nests, whether epigeous or arboreous. The only species that builds obligate subterranean nests, associated or not with termite or ant nests (Atta spp.) is P. testacea. Nests of Partamona have one vestibular chamber (autapomorphic for the genus) closely adjacent to the entrance, filled with a labyrinth of anastomosing pillars and connectives, made of earth and resins. One principal chamber exists for food and brood, but in some species one or more additional chambers are filled with food storage pots. In nests of P. vicina, there is one atrium or "false nest", between the vestibule and the brood chamber, which contains involucral sheaths, cells and empty pots. All structures of the nest are supported by permanent pillars made of earth and resins (another autapomorphy of the genus). The characters concerning nesting habits were coded and combined with morphological and biogeographic data, in order to hypothesize the evolutive scenario of the genus using cladistic methodology. The phylogenetic hypothesis presented is the following: (((((P. bilineata (P. grandipennis, P. xanthogastra)) (P. orizabaensis, P. peckolti)) (P. aequatoriana, P. musarum)) P. epiphytophila, P. yungarum, P. subtilis, P. vitae) (((((P. testacea (P. mourei, P. vicina)) (P. nigrior (P. auripennis, P. combinata))) (P. ferreirai (P. pearsoni (P. gregaria (P. batesi (P. chapadicola, P. nhambiquara)))))) ((((P. ailyae, P. sooretamae) P. cupira, P. mulata) P. seridoensis) P. criptica, P. rustica, P. littoralis)) P. helleri))). One area cladogram is presented. Dates of some vicariance / cladogenesis events are suggested. For bilineata / epiphytophila group, which inhabits the Southwestern Amazonia and the Chocó-Mexican biogeographical components, the origin of ancestral species is attributed to the Middle Miocene, when the transgressions of the Maracaibo and Paranense seas isolated the tropical northwestern South America from the eastern continental land mass. The next cladogenic event in the history of the bilineata / epiphytophila group is attributed to the Plio-Pleistocene, when the Ecuadorian Andes reached more than 3000 m, and the ancestral species was fragmented in two populations, one occupying the western Andes (ancestral species of the bilineata subgroup) and other the southwestern Amazon (ancestral species of the epiphytophila subgroup). Other aspects of the history of Partamona are also discussed.

Lectotypes of P. orizabaensis (Strand, 1919), and P. cupira (Smith, 1863) are designated. An identification key for the species and drawings of morphological characters are presented. A phylogenetic hypothesis, based mainly on morphological characters is proposed. Four groups are defined, considering the shape of mandible of workers and sternum VII of males: bilineata / epiphytophila group (western Amazon to México), including P. bilineata (Say), P. grandipennis, P. xanthogastra P. orizabaensis P. peckolti P. epiphytophila sp. nov., P. subtilis sp. nov., P. nhambiquara sp. nov., P. batesi sp. nov., P. yungarum sp. nov. and P. vitae sp. nov.; musarum group (Central Brazil, north of South America to Central America), including P. musarum, P. aequatoriana, P. vicina, P. mourei, P. pearsoni, P. ferreirai sp. nov., P. gregaria sp. nov. and P. testacea; nigrior group (Central Brazil to northeast of South America) including P. nigrior (Cockerell, 1925), P. auripennis sp. nov., P. nigrilabris sp. nov., P. combinata sp. nov., P. chapadicola sp. nov., P. seridoensis sp. nov. and P. littoralis sp. nov., and cupira group (southeastern and Central Brazil), including P. cupira, P. mulata, P. ailyae, P. sooretamae sp. nov., P. criptica sp. nov., P. rustica sp. nov. and P. helleri. Some geographic distribution patterns, congruent with that of other Meliponini bees, are commented.
