Distribution. Brazil (Amapá, Amazonas, Pará).

Remarks. This species was recently described by Marques et al. (2022) based on specimens from the state of Amazonas. Therefore, it is newly recorded from the states of Amapá and Pará.

The specimen from state of Amapá differs from other specimens, including the type-specimens in having an enlarged and almost pyriform first flagellomere ( Fig. 14A ). We decided to consider this as an intraspecific variation rather than a diagnostic feature of a new species, since all the other features are similar to those of the type-specimens. In addition, we were not able to examine the male terminalia, since it is a female specimen.
