[1] L. adiketis is a vector of the extinct Paleoleishmania neotropicum and both species are solely known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.

[1] The specimen was collected from an unidentified amber mine in the Cordillera Septentrional between Puerto Plata and Santiago de los Caballeros.

[1] The specific epithet "adiketis" was coined by the author as a derivation from the Greek word ἄδικος (adikos), meaning "injurious".

Found preserved in the proboscis and alimentary tract of the fly were hundreds of trypanosomatid parasites of the species Paleoleishmania neotropicum.

In contrast P. brazilorum, P. killickorum, Lutzomyia filipalpis, L. miocena, L. paleopestis, L. schleei, and L. succini all possess an Sc which meets the R1 vein.
