| description | The genus Alouatta (howler monkeys) is the most widely distributed of New World primates, and has been arranged in three species groups: the Central American Alouatta palliata group and the South American Alouatta seniculus and Alouatta caraya groups. While the latter is monotypic, the A. seniculus group encompasses at least three species (A. seniculus, A. belzebul and A. fusca). In the present study, approximately 600 base pairs of the g1-globin pseudogene were sequenced in the four Brazilian species (A. seniculus, A. belzebul, A. fusca and A. caraya). Maximum parsimony and maximum likelihood methods yielded phylogenetic trees with the same arrangement: {A. caraya [A. seniculus (A. fusca, A. belzebul)]}. The most parsimonious tree had bootstrap values greater than 82% for all groupings, and strength of grouping values of at least 2, supporting the sister clade of A. fusca and A. belzebul. The study also confirmed the presence of a 150-base pair Alu insertion element and a 1.8-kb deletion in the g1-globin pseudogene in A. fusca, features found previously in the remaining three species. The cladistic classification based on molecular data agrees with those of morphological studies, with the monospecific A. caraya group being clearly differentiated from the A. seniculus group.<br>Os guaribas, do gênero Alouatta, que são os primatas do Novo Mundo com maior distribuição geográfica, têm sido colocados em três grupos de espécies: o grupo Alouatta palliata da América central, e os grupos sulamericanos Alouatta seniculus e Alouatta caraya. Este último é monotípico, mas o grupo A. seniculus inclui pelo menos três espécies (A. seniculus, A. belzebul e A. fusca). Neste estudo, foram seqüenciados aproximadamente 600 pares de base do pseudogene globina g1 nas quatro espécies brasileiras (A. seniculus, A. belzebul, A. fusca e A. caraya). Os métodos de máxima parcimônia e máxima verossimilhança produziram árvores filogenéticas com o mesmo arranjo: {A. caraya [A. seniculus (A. fusca, A. belzebul)]}. A árvore mais parcimoniosa apresentou valores de bootstrap maiores de 82% para todos os agrupamentos, e valores de força de ligação de pelo menos 2, apoiando o agrupamento irmão de A. fusca e A. belzebul. O estudo também confirmou a presença em A. fusca do elemento de inserção Alu, com 150 pares de base, e uma deleção de 1,8 kb no pseudogene globina g1 já conhecidos nas demais espécies de guaribas. A classificação cladística baseada em dados moleculares é congruente com as de estudos morfológicos, com um isolamento claro do grupo monoespecífico A. caraya em relação ao grupo A. seniculus. |
