Abstract

The understanding of the subfamily Landrevinae has been modified by different authors since its creation. In the neotropics three genera are known to the present: Odontogryllus Saussure, 1877 (one from México, the others amazonian), Brasilodontus de Mello, 1992 with two species (from Brazilian Atlantic Forest), e Valchica de Mello, 1992 with one species (from Costa Rica). De Mello (1992) erroneously created the tribe Odontogryllini for this cluster of neotropical genera, here suppressed. In the present paper we revise and add new species to Brasilodontus and describe two monotypic genera, Xulavuna n. gen. and Yarrubura, n. gen. An identification key to the genera of neotropical Landrevinae is presented as well as one for the species of Brasilodontus. The male fore wings of Xulavuna adenoptera n. sp. is remarkable regarding its shape and its glandular condition.

摘要

自亚科Landrevinae创立以来，不同作者对其的理解有所改变。在新热带界，目前已知三个属：1877年的奥氏蟋属（Odontogryllus Saussure）（一个来自墨西哥，其他来自亚马逊地区），1992年的巴西蟋属（Brasilodontus de Mello）有两个物种（来自巴西大西洋森林），以及1992年的瓦尔基蟋属（Valchica de Mello）有一个物种（来自哥斯达黎加）。德梅洛（1992年）错误地为这一新热带界属的类群创建了奥氏蟋族（Odontogryllini），在此予以废除。在本文中，我们对巴西蟋属进行了修订并增添了新物种，还描述了两个单型属，即新属Xulavuna和新属Yarrubura。给出了新热带界Landrevinae属的检索表以及巴西蟋属物种的检索表。新种Xulavuna adenoptera的雄性前翅在形状和腺体状况方面很显著。
