Abstract
The ultrastructure of the egg chorionic sculpturing of eight neotropical sand fly species ( Lutzomyia townsendi (Ortiz, 1959), L. youngi Feliciangeli & Murillo, 1987, L. spinicrassa Osorno, Morales, Osorno, & Hoyos, 1969, L. evansi Nuñez Tovar 1924, L. lichyi, Floch & Abonnenc, 1950, L. trinidadensis Newstead, 1922, L. venezuelensis Floch & Abonnenc, 1948, and L. olmeca bicolor, Fairchild & Theodor, 1971) was studied using scanning electron microscopy (SEM). A new pattern, ellipses bound by fine longitudinal ridges, was observed in L. venezuelensis. Moreover, the chorionic ultrastructure was useful for separating three isomorphic species ( L. townsendi, L. youngi, and L. spinicrassa), of which L. youngi and L. spinicrassa are sympatric in some endemic foci of Táchira State, Venezuela.Keywords
