Descubra-se todos os dias, deixe-se levar pelas vontades, mas não enlouqueça por elas. Procure, sempre procure o fim de uma história, seja ela qual for. Dê um sorriso para quem esqueceu como se faz isso. Acelere seus pensamentos, mas não permita que eles te consumam. Olhe para o lado, alguém precisa de você. Abasteça seu coração de fé, não a perca nunca. Mergulhe de cabeça nos seus desejos e satisfaça-os. Procure os seus caminhos, mas não magoe ninguém nessa procura. Arrependa-se, volte atrás, peça perdão! Não se acostume com o que não o faz feliz, revolte-se quando julgar necessário. Alague seu coração de esperanças, mas não deixe que ele se afogue nelas. Se achar que precisa voltar, volte! Se perceber que precisa seguir, siga! Se estiver tudo errado, comece novamente. Se estiver tudo certo, continue. Se sentir saudades, mate-a. Se perder um amor, não se perca! Se achá-lo, segure-o!” (Fernando Pessoa) AGRADECIMENTOS Meus sinceros agradecimentos: À Deus, primeiramente, por me permitir concluir esta vitória e ter paciência nos momentos difíceis, sempre guiando minha vida e norteando minhas decisões. À meus pais, Edilmar Leite e Rosana Cuquetto Leite, exemplos de amor, força e sabedoria, que desde minha infância me incentivaram a estudar e dar o melhor de mim.

RESUMO Apesar de Formicidae constituir um dos grupos animais mais significativos em riqueza de espécies no Brasil, suas relações filogenéticas permanecem controversas. Uma notável fonte de caracteres para análises taxonômicas e filogenéticas é a caracterização espermática e do aparelho reprodutor. Tal caracterização tem se mostrado uma ferramenta na clarificação de questões da biologia reprodutiva e sistemática de diversos grupos de insetos. Desta forma, o presente estudo analisou, através de microscopia de luz e eletrônica de transmissão, a morfologia espermática de quatro espécies do gênero Pachycondyla (Formicidae: Ponerinae), bem como o aparelho reprodutor masculino: P. marginata, P. termitofane comutata, P. harpax e P. striata. A ultraestrutura dos espermatozoides de tais espécies é semelhante à descrita para outros Hymenoptera por apresentar: (1) acrossomo cônico do tipo bicamada; (2) adjunto do centríolo situado entre o núcleo e ambos os derivados mitocondriais e (3) flagelo constituído por dois derivados mitocondriais alongados, dois corpos acessórios triangulares e um axonema de padrão 9+9+2. Entretanto, as mesmas compartilham inúmeras características cujas evidências indicam evoluir como homoplasia via paralelismo, não conferindo, pois, suporte para uma resolução filogenética entre tais espécies e demais clados próximos. Dentre estes caracteres se destacam a organização espacial dos componentes acrossomais, o caráter cromatínico nuclear, a configuração da extremidade da transição núcleo-flagelo, além da condição simétrica do adjunto do centríolo. Além dessas, várias outras características corroboram a definição do estado parafilético do respectivo gênero, tais como o aspecto cromatínico, a condição simétrica do adjunto do centríolo e a organização terminal flagelar, por serem compartilhadas entre determinadas espécies de Pachycondyla e grupos filogeneticamente distantes, evidenciando, pois, as divergências dentro da mesma espécie. Por fim, a análise morfológica do aparelho reprodutor de P. marginata e P. striata evidenciou a existência de um padrão morfológico reprodutivo para Formicidae, uma vez que tais espécies exibiram íntima similaridade às descrições realizadas à respectiva família. Palavras-chave: Ultraestrutura espermática, Morfologia reprodutiva, Ponerini. ABSTRACT Although Formicidae be one of the most important animal groups in species richness in Brazil, their phylogenetic relationships remain controversial. One notable source of characters for taxonomic and phylogenetic analysis is the characterization of the spermatozoa and male reproductive tract. This characterization has shown to be a tool in clarifying issues of reproductive biology and systematics of many insect groups. Thus, this study analyzed by light and transmission electron microscopies, the sperm morphology of four species of the genus Pachycondyla (Formicidae: Ponerinae), and their male reproductive system: P. marginata, P. termitofane comutata, P. harpax and P. striata. The ultrastructure of spermatozoa of these four species is similar to that described to other Hymenoptera: (1) bilayer tapered acrosome; (2) centriolar adjunct located between nucleus and both mitochondrial derivatives and (3) flagellum comprises two elongate mitochondrial derivatives, two triangular bodies and an axoneme of 9 + 9 + 2 pattern. However, they share a number of features whose evidence indicates evolve as homoplasy via parallelism, not giving, support for a phylogenetic resolution among species and other nearby clades. Among these characters stand out, the spatial organization of acrosomal components, the nuclear chromatin character, setting the end of the transition nucleus-flagellum, in addition to symmetrical condition centriolar adjunct. Besides these, various other features confirm the setting of the paraphyletic status of its genus, such as chromatin aspect, symmetrical condition centriolar adjunct and flagellar terminal organization, by being shared among certain species phylogenetically distant and Pachycondyla groups, highlighting, therefore, the differences within the same species. Finally, the morphological analysis of the reproductor system of P. striata and P. marginata highlighted the existence of a reproductive morphology pattern to Formicidae, since such species showed close similarity to the descriptions made to its family.

  • Phylogeny of the Bee Family Megachilidae (Hymenoptera: Apoidea) Based on Adult Morphology
    Systematic Entomology (2012), 37, 261–286 Phylogeny of the bee family Megachilidae (Hymenoptera: Apoidea) based on adult morphology VICTOR H. GONZALEZ1, TERRY GRISWOLD1,CHRISTOPHEJ. PRAZ2,3 and BRYAN N. DANFORTH2 1USDA-ARS, Bee Biology and Systematics Laboratory, Utah State University, Logan, UT, U.S.A., 2Department of Entomology, Cornell University, Ithaca, NY, U.S.A. and 3Laboratory of Evolutionary Entomology, University of Neuchatel, Neuchatel, Switzerland Abstract. Phylogenetic relationships within the bee family Megachilidae are poorly understood. The monophyly of the subfamily Fideliinae is questionable, the relation- ships among the tribes and subtribes in the subfamily Megachilinae are unknown, and some extant genera cannot be placed with certainty at the tribal level. Using a cladistic analysis of adult external morphological characters, we explore the rela- tionships of the eight tribes and two subtribes currently recognised in Megachilidae. Our dataset included 80% of the extant generic-level diversity, representatives of all fossil taxa, and was analysed using parsimony. We employed 200 characters and selected 7 outgroups and 72 ingroup species of 60 genera, plus 7 species of 4 extinct genera from Baltic amber. Our analysis shows that Fideliinae and the tribes Anthidiini and Osmiini of Megachilinae are paraphyletic; it supports the monophyly of Megachilinae, including the extinct taxa, and the sister group relationship of Lithurgini to the remaining megachilines. The Sub-Saharan genus Aspidosmia,a rare group with a mixture of osmiine and anthidiine features, is herein removed from Anthidiini and placed in its own tribe, Aspidosmiini, new tribe. Protolithurgini is the sister of Lithurgini, both placed herein in the subfamily Lithurginae; the other extinct taxa, Glyptapina and Ctenoplectrellina, are more basally related among Megachilinae than Osmiini, near Aspidosmia, and are herein treated at the tribal level.

ABSTRACT. The structure of native bee communities was studied in four vegetation types in the state of Yucatan, Mexico. Community structure was established using índices (dominant, common and rare species), four lifeways and unique species. A total of 5, 701 specimens were collected, falling in five families, 55 genera and 140 species. Community structure was equal, and independent ofvegetation type. On average, rare species represented 51.2% of community structure, common species 31.2% and dominant species 17.6%, while parasocials represented 50.8%, solitaries 30.1%, eusocials 9.1% and parasitic 7.5%. Results suggest that parasocial species are the most important in terms of dominance and richness and that the sampled vegetation associations are rich in social bees. This coincides with descriptions demonstrating that eusocial Apidae and Halictidae are most common and abundant. The bee communities do not differ in the size and composition of dominant, common, and rare species assemblages, or in strata composition.

Gonzalez1,2, Grey T. Gustafson2,3, & Michael S. Engel2,3,4 Abstract. A unique feature among bees is the ability of some species of Megachile Latreille s.l. to cut and process fresh leaves for nest construction. The presence of a razor between the female mandibular teeth (interdental laminae) to facilitate leaf-cuting (LC) is a morphological novelty that might have triggered a subsequent diversifcation in this group. However, we have a lim- ited understanding of the phylogeny of this group despite the large number of described species and the origins and paterns of variations of this mandibular structure are unknown. Herein, using a cladistic analysis of adult external morphological characters, we explored the relation- ships of all genera of Megachilini and the more than 50 subgenera of Megachile s.l. We coded 272 characters for 8 outgroups and 114 ingroup species.
