INTRODUCTION
We aimed to study intraspecific variation in Triatoma costalimai, a potential vector of Chagas disease present in Brazil and Bolivia.
METHODS
We analyzed phenotypic (connexivum color patterns, wing morphometrics) and genetic variation (16S mtDNA) of three Brazilian T. costalimai populations. We compared 16S sequences with those of putative Bolivian T. costalimai and its sister species, T. jatai.
RESULTS
Brazilian populations had different connexivum color patterns and forewing shapes. A 16S mtDNA haplotype network showed a clear separation of Brazilian T. costalimai from both T. jatai and Bolivian T. costalimai.
CONCLUSIONS
We report considerable variability in T. costalimai populations.
简介
本研究旨在分析分布于巴西和玻利维亚的查加斯病潜在传播媒介——三带喙库蚊的种内变异。
方法
我们分析了三个巴西三带喙库蚊种群的表型（连索器颜色模式、翅形态计量学）和遗传变异（16S mtDNA）。我们将 16S 序列与可能的玻利维亚三带喙库蚊及其姊妹种 T. jatai 的序列进行了比较。
结果
巴西种群的连索器颜色模式和前翅形状存在差异。16S mtDNA 单倍型网络清楚地区分了巴西三带喙库蚊与 T. jatai 和玻利维亚三带喙库蚊。
结论
我们报告了三带喙库蚊种群存在相当大的变异性。
