Diversity among Lutzomyia longipalpis populations in Venezuela was characte
rized using 2 methods: larval mouthpart morphology-morphometry and isoenzym
e electrophoresis. Analysis of the results suggested the presence of 2 morp
ho-genotypes. The mentum, maxillary comb, mandibular ventral teeth, and ade
nylate kinase and hexokinase enzyme-encoding loci suggested that a populati
on from the northwestern Coriano System (Curarigua) is a distinct lineage w
ithin the L. longipalpis complex. Three widely separated populations from t
he Llanos (savanna), Andes, and northcentral Coastal Cordillera showed no s
ignificant substructure. These studies provide morphologic markers that are
congruent with genetic data and suggest that the morphologic markers may b
e used to characterize and differentiate populations within this species co
mplex.
