Abstract With the aim of further investigating phylogenetic relationships in insect trypanosomatids, we have determined the sequences of small subunit rRNA genes from ten isolates, which were originally classified as Leptomonas, Blastocrithidia, and Wallaceina based on their morphology in the hosts. The inferred maximum likelihood, parsimony, and distance trees indicate that the Leptomonas and Blastocrithidia are polyphyletic, and confirm the polyphyly of Herpetomonas and Crithidia…

Phylogeny of the kinetoplastida: taxonomic problems and insights into the evolution of parasitism.
TLDR
It is shown that the morphological classification of kinetoplastids does not in general reflect their genetic affinities and needs a revision.
New Species of Insect Trypanosomatids from Costa Rica and the Proposal for a New Subfamily within the Trypanosomatidae
TLDR
A proposal is put forward to recognize this natural taxon as a new subfamily, Leishmaniinae, within the family Trypanosomatidae, based on the high phylogenetic support for this clade, which is consistently recovered in all recent phylogenetic reconstructions.
Molecular phylogenetic redefinition of Herpetomonas (Kinetoplastea, Trypanosomatidae), a genus of insect parasites associated with flies.
An Integrated Morphological and Molecular Approach to a New Species Description in the Trypanosomatidae: the Case of Leptomonas podlipaevi n. sp., a Parasite of Boisea rubrolineata (Hemiptera: Rhopalidae)
TLDR
Molecular phylogenetic analysis has demonstrated that the new species is most closely related to Leptomonas seymouri and Leptonomonas pyrrhocoris, and has highlighted the polyphyly of the genus LePTomonas.
Patterns of co-evolution between trypanosomes and their hosts deduced from ribosomal RNA and protein-coding gene phylogenies.
Evaluating the role of morphological characters in the phylogeny of some trypanosomatid genera (Excavata, Kinetoplastea, Trypanosomatida)
TLDR
The belief that morphological characters are inferior to molecular ones for trypanosomatid systematics is demonstrated to be a consequence of neglecting their inclusion in phylogenetic analyses.
Probing into the diversity of trypanosomatid flagellates parasitizing insect hosts in South-West China reveals both endemism and global dispersal.
Genetic diversity of insect trypanosomatids from subarctic and North West Russia revialed by up PCR typing
TLDR
This paper is the first one aimed at revealing the presence and biodiversity of insect trypanosomatids from hosts inhabiting high latitude areas and has demonstrated that trypanOSomatid fauna in subarctic regions is diverse.
Trypanosomatid biodiversity in Costa Rica: genotyping of parasites from Heteroptera using the spliced leader RNA gene
TLDR
Only a minor fraction of the trypanosomatid biodiversity is revealed, which is anticipated to be high, and cluster analysis indicated that these typing units were unique and thus could represent new species and, in some cases, new genera.
Diversity of Insect Trypanosomatids Assessed from the Spliced Leader RNA and 5S rRNA Genes and Intergenic Regions1
TLDR
The data revealed additional discrepancies between molecular phylogenetic data and cell morphology, rendering current trypanosomatid taxonomy unreliable, and several isolates seem to belong to a single species with an unexpectedly wide host and geographical range.

Monophyly of Endosymbiont Containing Trypanosomatids: Phylogeny versus Taxonomy
TLDR
Data support the hypothesis of a monophyletic origin of endosymbiosis in trypanosomatid evolution and suggest that a taxonomic revision is needed in order to better describe the natural affinities in this family.

Evolution of nuclear ribosomal RNAs in kinetoplastid protozoa: perspectives on the age and origins of parasitism.
TLDR
Analysis of the distribution of different parasitic life-styles of these species in conjunction with a probable timing of evolutionary divergences suggests that vertebrate parasitism arose multiple times in the trypanosomatids.
Phylogeny of the bodonid flagellates (Kinetoplastida) based on small-subunit rRNA gene sequences.
TLDR
The phylogeny of kinetoplastid flagellates was investigated and indicated that the genera Cryptobia and Bodo are artificial taxa, while the separation of the fish cryptobias and Trypanoplasma borreli as different genera was not supported.

TLDR
The data provides strong evidence for a Neotropical origin of the Endotrypanum/Leishmania clade since the parasites closest to the root of the tree are all found exclusively in the Neotropics.
