Neighbor-joining tree of <i>COI</i> sequence divergences (K2P) obtained from 567 specimens of sand flies analyzed.

<p>Numbers next to the branches indicate Bootstrap percentages ≥80%. One black dash indicates groups partitioned by ABGD using the value of 2.15%. One white dash indicates the groups partitioned by ABGD using the cut-off of 1.29%. Two thin black dashes indicated groups that were not recognized by the ABGD partitions. The number of specimens is indicated behind each species name. PS1, PS2, and PS3 represent distinct groups that are hypothesized to represent provisional species.
