 en Molecular phylogeny of the Myzorhynchella Section of Anopheles check for this species in other resources (Nyssorhynchus) (Diptera: Culicidae): genetic support for recently described and resurrected species

Abstract

Phylogenetic relationships among species of the Myzorhynchella Section of Anopheles check for this species in other resources (Nyssorhynchus) were investigated using the nuclear ribosomal DNA second internal transcribed spacer (ITS2), the nuclear whitegene and mitochondrial cytochrome oxidase subunit I (COI) regions. The recently described Anopheles pristinus check for this species in other resources and resurrected Anopheles guarani check for this species in other resources were also included in the study. Bayesian phylogenetic analyses found Anopheles parvus check for this species in other resources to be the most distantly related species within the Section, a finding that is consistent with morphology. An. pristinus and An. guarani were clearly resolved from Anopheles antunesi and Anopheles lutzii, respectively. An. lutzii collected in the same mountain range as the type locality were found within a strongly supported clade, whereas individuals from the southern state of Rio Grande do Sul, tentatively identified as An. lutzii based on adult female external morphology, were distinct from An. lutzii, An. antunesi and from each other, and may therefore represent two new sympatric species. A more detailed examination of An. lutzii sensu latoalong its known geographic range is recommended to resolve these anomalous relationships.
