 en Lutzomyia derelicta (Diptera: Psychodidae) a Singular New Phlebotomine Sand Fly from an Inselberg in Northeastern Amazonia
Rui A Freitas & Toby V Barrett

Abstract

Lutzomyia derelicta n. sp. is described from specimens collected in an isolated xeric habitat in the rainforest in the north of the State of Pará, Brazil. The new species lacks the posterior bulge in the dorsal wall of the cibarium characteristic of the New World genus Lutzomyia, and the armature of the male genitalia is of the pattern found elsewhere only in the Old World species of Sergentomyia. L. derelicta is phenetically intermediate between the known species of Lutzomyia and Sergentomyia, and cannot readily be placed in any existing subgenus or species group of either genus.
