A new species of phlebotomine sand fly, Lutzomyia emberai n. sp, is described and illustrated from specimens collected in a dwelling of the Emberá Indian community, situated in the foothills of the Serranía del Baudó on the Colombian Pacific coast. The morphological characteristics of L. emberai n. sp. suggest that it belongs to the series pia of the group verrucarum, easily differentiated from the other members of this group by diagnostic characters on the palps, labro-pharynx, thorax, and spermathecal ducts. The discovery of this new phlebotomine raises to seven the number of species in the series pia, including Lutzomyia pia (Fairchild & Hertig, 1961); Lutzomyia reclusa Fernandez & Rogers, 1991; Lutzomyia suapiensis Le Pont, Torrez-Espejo & Dujardin, 1997; Lutzomyia tihuiliensis Le Pont, Torrez-Espejo & Dujardin, 1997; Lutzomyia tocaniensis Le Pont, Torrez-Espejo & Dujardin, 1997; Lutzomyia limafalcaoae (Wolff & Galati, 2002); and Lutzomyia emberai Bejarano, Duque & Velez, 2004, n. sp. The taxonomy, distribution, and medical importance of this series are reviewed.
