The morphometrics of the median process of the male pygophore of four species of blood-sucking bugs (Rhodnius prolixus, R. robustus, R. nasutus and R. neglectus) were compared using one-way analysis of variance. Although there were no significant differences in the pygophoral patterns within the R. nasutus-R. neglectus or R. prolixus-R. robustus species pairs, there were clear-cut differences between them; the median process of R. nasutus-R. neglectus is stout and subtriangular whereas that of R. prolixus-R. robustus is more narrow and elongated. The basal width of the process, classically used to separate R. robustus from R. prolixus and R. nasutus from R. neglectus, seems to have little taxonomic value. Other characters which have been assumed to be species-specific should be subjected to a similar quantitative analysis.
使用单因素方差分析比较了四种吸血蝽（罗阿丝虫、强壮罗阿丝虫、鼻罗阿丝虫和疏忽罗阿丝虫）雄性尾节中间突起的形态测量学特征。尽管在鼻罗阿丝虫 - 疏忽罗阿丝虫或罗阿丝虫 - 强壮罗阿丝虫物种对中，尾节模式没有显著差异，但它们之间存在明显差异；鼻罗阿丝虫 - 疏忽罗阿丝虫的中间突起粗壮且呈近三角形，而罗阿丝虫 - 强壮罗阿丝虫的中间突起更窄且细长。传统上用于区分强壮罗阿丝虫与罗阿丝虫以及鼻罗阿丝虫与疏忽罗阿丝虫的突起基部宽度，似乎没有什么分类学价值。其他被认为是物种特异性的特征也应进行类似的定量分析。
