Phlebotomus ariasi Tonnoir, 1921
Subgenus: Larroussius Nitzulescu, 1931
Females of P. ariasi and P. chadli are distinguished from the other Larroussius females by their spermathecal ducts without any lateral structures and dilated at the base. The discrimination between the females of these two species mainly relies on the length of the dilated part of the ducts.
