The systematics of Phlebotomine sandflies has been studied and discussed since the beginning of the 20th century, and many systems have been proposed. Complex and well-based systems, dividing Phlebotominae in many genera and subgenera, proposed for Old and New World species, have been progressively understood and accepted by the workers in the subfamily. Due to its complex nature, a system of abbreviations, similar to that utilized for Culicidae, is proposed here for these groups of Phlebotominae. It uses two letters for genera and three for subgenera.
