Meris paradoxa Rindge, thought to be restricted to southeastern Arizona, is documented in Mexico for the first time. Previously described only from males, we provide the first description of the female from specimens collected as caterpillars and reared to adults. We find female M. paradoxa to have a normal haustellum; an external diagnostic character for this species previously only confirmed in conspecific males. Female genitalia of M. paradoxa are found similar to other Meris, but the absence of a sclerotized signum (present in congeners) may prove autapomorphic. Natural history information for the genus is discussed in light of new data reported here for Mexican M. paradoxa.
梅里斯悖论是一种被认为仅限于美国亚利桑那州东南部的物种，此次在墨西哥有了首次记录。此前仅从雄性个体中描述过该物种，我们提供了首次从幼虫期采集并饲养至成虫的雌性个体的描述。我们发现，雌性梅里斯悖论具有正常的吸器；这个物种的一个外部诊断特征，此前仅在同种雄性中得到确认。梅里斯悖论的雌性生殖器与其他梅里斯相似，但缺乏一个硬化的指示物（存在于近缘种中），这可能是一个独特的特征。根据这里报告的墨西哥梅里斯悖论的新数据，讨论了该属的自然历史信息。
