Resumen:
The sand fly Psathyromyia shannoni is a broadly distributed species that
is relevant for the transmission of pathogens such as Leishmania,
Bartonella and viruses in several countries of America. This species
belongs to the Shannoni complex. Yet its identification is difficult due
to morphologic intraspecific polymorphisms that make it difficult to
distinguish between species, and could therefore lead to
misidentification and overestimation of its distribution. The aim of
this study was to perform a retrospective study on the genetic diversity
of Pa. shannoni based on the Cytochrome Oxidase subunit 1 gene and
considering its geographic distribution to achieve a better
identification and differentiation from other species of the Shannoni
complex. According to the Maximum Likelihood analysis and the data on
the genetic structure, we propose a modified delimitation of Pa.
shannoni species by classifying it into at least three genetic lineages,
based on genetic variability and distribution. However, more genetic
information on the COI gene, mainly from countries where this species
has been reported, is needed to strengthen this proposal.
