Diversity among Lutzomyia longipalpis populations in Venezuela was characterized using 2 methods: larval mouthpart morphology-morphometry and isoenzyme electrophoresis. Analysis of the results suggested the presence of 2 morpho-genotypes. The mentum, maxillary comb, mandibular ventral teeth, and adenylate kinase and hexokinase enzyme-encoding loci suggested that a population from the northwestern Coriano System (Curarigua) is a distinct lineage within the L. longipalpis complex. Three widely separated populations from the Llanos (savanna), Andes, and northcentral Coastal Cordillera showed no significant substructure. These studies provide morphologic markers that are congruent with genetic data and suggest that the morphologic markers may be used to characterize and differentiate populations within this species complex.
幼虫口器形态测量和同工酶电泳。结果分析表明存在两种形态基因型。下唇、上颚梳、下颚腹齿以及腺苷酸激酶和己糖激酶酶编码位点表明，来自西北科里亚诺系统（库拉里瓜）的一个种群是长须罗蛉复合体中的一个独特谱系。来自草原、安第斯山脉和中北部沿海山脉的三个相距甚远的种群没有明显的亚结构。这些研究提供了与遗传数据一致的形态学标记，并表明这些形态学标记可用于表征和区分该物种复合体内的种群。
