ABSTRACT The neotropical Menenotus Laporte, 1832 includes M. lunatus and M. diminutus Walker, 1871. The genus has never been reviewed, and only the brief original descriptions were available so far. In this paper, we review Menenotus and describe, for the first time, genital traits of both sexes. Menenotus lunatus and M. diminutus are distinguishable by the shape of pronotum, the color pattern of connexivum, the extension of the cuplike sclerite, and the shape of the parameres, among other traits. In addition, Menenotus is compared with Euagona Dallas, 1852, which shares the prominent and curved humeri. These genera can be distinguished by the broader abdomen and the apparent connexivum in Menenotus. Their distribution pattern is different, with Euagona showing a more northern distribution in South America than Menenotus. We also updated the distribution records in Brazil, providing a map to the species of Menenotus. |
