Abstract

Odontogryllini is a tribe of ground-dwelling crickets exclusive to America. After several taxonomic rearrangements, this tribe has five genera and 23 species now placed in the subfamily Landrevinae. These crickets have dorsoventrally depressed bodies and are moderately to densely covered with bristles. The males may bear tegminal, metanotal, or tergal glands. In this contribution, we discuss the taxonomic status and the morphological features of Odontogryllini and the other two tribes of Landrevinae: Landrevini and Prolandrevini. The presence of dorsal spines between the outer spurs of the hind tibia distinguishes Odontogryllini from Prolandrevini, and the straight or slightly arcuate but never S-shaped stridulum from Landrevini. We also propose the enlarged and plate-like rami as a diagnostic characteristic to distinguish Odontogryllini from Landrevini. Additionally, we describe a new species of the genus Xulavuna de Mello & Campos from the Brazilian Amazon Rainforest, named Xulavuna krenakore sp. nov..

对Odontogryllini（直翅目：蝼蛄：Landrevinae）的贡献，以及对其分类学地位的评论和对Xulavuna de Mello & Campos新种的描述，2014年。

蟋蟀亚科（Odontogryllini）是美洲独有的地栖蟋蟀科。经过数次分类重排，该族有 5 属 23 种，现归入陆蟋亚科。这些蟋蟀的身体背腹下凹，被中等程度到密集的刚毛覆盖。雄性蟋蟀可能带有胫腺、跖腺或跗腺。在这篇论文中，我们将讨论Odontogryllini和Landrevinae的其他两个部落的分类地位和形态特征：Landrevini和Prolandrevini。后胫骨外刺之间背刺的存在将 Odontogryllini 与 Prolandrevini 区分开来，而笔直或略带弧形但绝非 S 形的股沟则将 Odontogryllini 与 Landrevini 区分开来。我们还建议将增大的板状嵴作为区分 Odontogryllini 和 Landrevini 的诊断特征。此外，我们还描述了来自巴西亚马逊雨林的 Xulavuna de Mello & Campos 属的一个新种，命名为 Xulavuna krenakore sp.

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
