Abstract

Mitotic metaphase chromosomes (2n = 8 ) from brain cells of fourth instar sandfly larvae of four geographical strains of the Lutzomyia longipaplis complex were examined microscopically, with bright-field illumination, after staining by a new G-banding technique involving exposure of air-dried chromosome preparations to quinacrine and ultraviolet light. Differences of G-banding and/or position of the centromere on chromosome 4 (the smallest chromosome pair) distinguished four putative sibling species from Costa Rica, Colombia and Brazil (distinctive populations from Jacobina and Lapinha Caves). The karyotype of;tbe population from Jacobina, Brazil, showed an apparently plesiomorphic pattern of G-banding. On the basis of their recognizably different mitotic karyotypes, cytogenetic identification of separate taxa inthe L. longipalpis complex should be useful for specific female vector competence and ecology studies.
