Three new species of the Neotropical genus Smilidarnis Andrade (Hemiptera, Membracidae)

Abstract

Smilidarnis duocornus sp. nov., S. erwini sp. nov., and S. robustus sp. nov. are described, illustrated, and included in a key to the five species here recognized in Smilidarnis. One member of this genus, from Ecuador (new country record for genus), is S. erwini, which differs from its congeners in having distinct coloration and being of intermediate size in terms of overall body length and the relative length of the lateral apical spines. Smilidarnis robustus (from Peru) and S. duocornus (from Brazil) differ from the other species of Smilidarnis in having the pronotum bearing a pair of suprahumeral spines.
