| Sexual size dimorphism (SSD) although a widespread phenomenon among animals, is both enigmatic as to its proximate and ultimate causes and the scaling relationships between SSD and body size (Rensch's rule). We analyzed SSD at the intra- and interspecific levels in a number of representative species and genera of the major orthopteroid orders: Orthoptera, Phasmatodea, Mantodea, Blattodea, Dermaptera, Isoptera, and Mantophasmatodea. The vast majority of the species showed female biased SSD but numerous exceptions occur in cockroaches and earwigs. Rensch's rule and its converse are not common patterns at both, intra-and cross-species level, most species and genera showing an isometric relationship between male and female body sizes. In some but not all... |

| The Neotropical genus Aleuas Stål 1878 is constituted by nine recognized species, distributed in South America. This genus is closely related to Adimantus Stål 1878, Zygoclistron Rehn 1905 and Episcopotettix Rehn 1903 (Copiocerinae). Only four species of Aleuas have been reported in Argentina, covering different phytogeographical provinces: A. gracilis Stål 1878, A. lineatus Stål 1878, A. paranensis Carbonell 2008 and A. vitticollis Stål 1878. In this contribution we provide novel records for A. uruguayensis and illustrate the geographic distribution of the species. This work extends the known distribution range of the species as well as it contributes to the general knowledge on the Orthoptera diversity in Argentina. |
