is a Chagas disease vector that was found infected with in homes. As this species is endemic from Brazil (Bahia, Espírito Santo, Minas Gerais, and Rio de Janeiro) and no study comparing the specimens from different Brazilian states was conducted, we analyzed the genetic distance (16S rDNA, Cyt b, and COI mitochondrial genes) and the chromosomal characteristics for from Minas Gerais, Rio de Janeiro, and Espírito Santo. All specimens showed the same cytogenetic characteristics. On the other hand, the different mitochondrial genes demonstrated high intraspecific variation between the genetic distances of from different states ranging from 2.3% to 7.2%. Based on this, our results suggest that possibly what is characterized as is a complex of cryptic species (or subspecies).
是恰加斯病的一种传播媒介，曾在家中发现其感染。由于该物种在巴西（巴伊亚州、圣埃斯皮里图州、米纳斯吉拉斯州和里约热内卢州）流行，且尚未对来自不同巴西州的标本进行比较研究，因此我们分析了米纳斯吉拉斯州、里约热内卢州和圣埃斯皮里图州的 的遗传距离（16S rDNA、Cyt b 和 COI 线粒体基因）和染色体特征。所有标本均表现出相同的细胞遗传学特征。另一方面，不同的线粒体基因在来自不同州的 之间的遗传距离上表现出高度的种内变异，范围从 2.3%到 7.2%。基于此，我们的结果表明，所谓的 可能是一个隐种（或亚种）复合体。
