The species of the genus Mepraia Mazza, Gajardo Tobar and Jörg (Hemiptera, Reduviidae:Triatominae) exhibit polymorphism in their hemelytra. The females of all species are always micropterous, but the males can be micropterous, brachypterous, or macropterous. Mepraia gajardoi Frías, Henry and González (Hemiptera: Reduviidae) males are always brachypterous, Mepraia parapatrica Frías-Lasserre (Hemiptera: Reduviidae) males are macropterous or brachypterous and Mepraia spinolai (Porter) (Hemiptera: Reduviidae) males are macropterous, brachypterous, or micropterous. Here, we determined distinctive characteristics of the hemelytra of the males of these three species and found that the length of the hemelytra of the brachypterous males in these three species differs statistically, as does their shape and morphology. These differences are particularly apparent at the apex of the hemelytra, the anterior part of the corium, in the morphology and number of the ctenidia of coaptors, and presence or absence of the cross vein of the hemelytra. Based on this, we propose a key based on hemelytra characteristics to identify the males of the three Mepraia species.
梅普雷亚属（Mepraia）的马扎、加亚尔多·托巴尔和约尔格（半翅目，猎蝽科：锥蝽亚科）昆虫的半翅鞘呈现多态性。所有物种的雌性均为微翅型，但雄性可能是微翅型、短翅型或长翅型。加亚尔多伊梅普雷亚（Mepraia gajardoi）弗里亚斯、亨利和冈萨雷斯（半翅目：猎蝽科）的雄性总是短翅型，副邻接梅普雷亚（Mepraia parapatrica）弗里亚斯 - 拉塞尔（半翅目：猎蝽科）的雄性是长翅型或短翅型，而斯皮诺莱梅普雷亚（Mepraia spinolai）（波特）（半翅目：猎蝽科）的雄性是长翅型、短翅型或微翅型。在此，我们确定了这三个物种雄性半翅鞘的独特特征，发现这三个物种中短翅型雄性的半翅鞘长度在统计学上存在差异，其形状和形态也有差异。这些差异在半翅鞘顶端、革片前部、接合器栉齿的形态和数量以及半翅鞘横脉的有无方面尤为明显。基于此，我们提出了一个基于半翅鞘特征的检索表来鉴定这三种梅普雷亚属昆虫的雄性。
