Cryptic taxa in the morphospecies Bichromomyia flaviscutellata uncovered by expanded geographic sampling and COI DNA barcodes.
The Neotropical sand fly species Bichromomyia flaviscutellata is widely distributed and the main vector of Leishmania amazonensis. Previous molecular studies suggested that it comprises at least two morphologically cryptic taxa, but sampling has remained geographically limited. In this study, we expanded specimen colle...
