A new treehopper genus from Costa Rica, Mutilifolia, based on M. nishidai, new species, is described and illustrated. Mutilifolia is considered a member of the subfamily Smiliinae, tribe Telamonini based on characteristics of the pronotum, fore- and hind wing venation, and female genitalia. This genus superficially resembles the telamonine genera Antianthe, Archasia, and Hemicardiacus due to the highly elevated, foliaceous, and largely green pronotum, but the male style clasp of Mutilifolia with two recurved teeth differs greatly from the styles of any other presently known telamonine. Further collecting of treehoppers in the mountainous regions of Central America and Mexico, areas often neglected by collectors, may yield additional new Telamonini taxa.
基于新物种西氏多叶角蝉（Mutilifolia nishidai），描述并图示了来自哥斯达黎加的一个新的角蝉属——多叶角蝉属（Mutilifolia）。根据前胸背板、前翅和后翅脉以及雌性生殖器的特征，多叶角蝉属被认为是角蝉亚科（Smiliinae）、泰氏角蝉族（Telamonini）的成员。由于前胸背板高度隆起、叶状且大部分为绿色，该属表面上类似于泰氏角蝉族的Antianthe属、Archasia属和Hemicardiacus属，但多叶角蝉属雄性抱握器有两个弯曲的齿，与目前已知的任何其他泰氏角蝉族的抱握器有很大不同。在中美洲和墨西哥山区进一步采集角蝉，这些地区常被采集者忽视，可能会发现更多新的泰氏角蝉族分类单元。
