Identification of Lutzomyia spp. (Diptera: Psychodidae) verrucarum group through electron microscopy of its eggs

The value of Colombian phlebotomine eggs for species determination was studied with a scanning electron microscope. The species diversity and medical importance of the verrucarum group were the bases to select Lutzomyia youngi, Lutzomyia evansi, Lutzomyia columbiana and Lutzomyia longiflocosa. The egg surface was poligonal. Lutzomyia youngi, and Lutzomyia columbiana had pentagonal or hexagonal patterns; Lutzomyia evansi elongated polygons and Lutzomyia longiflocosa irregular polygonal sculpturing, frequently rectangular. Egg scanning electron microscopy is reliable to identify species of the verrucarum group.
