Title in Portuguese
Diversidade e filogenia de tripanossomatídeos parasitas de dípteros.
Keywords in Portuguese
Diptera
Insetos parasitas
Abstract in Portuguese
A família Trypanosomatidae compreende parasitas obrigatórios de vertebrados, plantas e invertebrados, as espécies exclusivas de insetos infectam principalmente dípteras e hemípteras. Nós revisamos a taxonomia de Herpetomonas e tripanossomatídeos de insetos que abrigam simbionte (SHT), comparando tripanossomatídeos da América do Sul e África. As filogenias revelaram duas novas espécies e possibilitou revalidar os gêneros Strigomonas e Angomonas. As análises filogenéticas revelaram três novas espécies de endossimbiontes proteobacteriano e apoiam a história evolutiva convergente entre hospedeiros e simbiontes. O DNA barcoding de 364 culturas de moscas identificaram 70 culturas (20%) como Angomonas, 71% deles de Calliphoridae. O gênero Herpetomonas compreende agora 13 espécies válidas, incluindo cinco novas espécies. Algumas espécies de Herpetomonas são parasitas generalistas de moscas e parecem ser tão cosmopolita como seus hospedeiros. Os taxon propostos podem ajudar a elaborar critérios mais eficientes para uma classificação melhor dos tripanossomatídeos.

Abstract in English
Trypanosomatidae comprises obligate parasites of vertebrates, plants and invertebrates, the species exclusive of insects infect mostly dipterans and hemipterans. We revise the taxonomy of Herpetomonas and Symbiont Harboring Trypanosomatids (SHTs), by comparing trypanosomatids from South America and Africa. The phylogenies disclosed two new species and revalidated the genera Strigomonas and Angomonas. Phylogenetic analyses revealed 3 new species of proteobacterial endosymbionts and support a co-divergent host-symbiont evolutionary history. DNA barcoding of 364 cultures from flies identified 70 cultures (20%) as Angomonas, 71% of them from Calliphoridae. The recent dispersion of calliphorids was important in the dispersal of Angomonas worldwide. The genus Herpetomonas now comprises 13 valid species including 5 new species. Some species of Herpetomonas are generalist parasites of flies and appear to be as cosmopolitan as their hosts. The proposed taxa may help to elaborate more efficient criteria for a better classification of the Trypanosomatidae.
