This article presents an intriguing new cricket species of the tribe Xenogryllini discovered in Northern Malawi. This is the first case of mute and deaf species in the subfamily Eneopterinae; it shows no stridulatory apparatus on short male forewings and no tympana on either side of fore tibiae in both sexes. We introduce the new species and its complete mitogenome and assess phylogenetic relationships based on molecular data obtained from next-generation sequencing genome skimming method. Phylogenetic analyses place the new species within the genus in Xenogryllini, as the sister species of Robillard. We describe sp. nov., provide illustrations of main morphology, male and female genitalia, photographs of living specimens and information about habitat and update the identification key for species of genus . We discuss the differences between the new species and related taxa and the striking loss of acoustic communication in this cricket.
本文介绍了在马拉维北部发现的一种有趣的新蟋蟀物种，属于Xenogryllini族。这是Eneopterinae亚科中首次发现的静音和失聪物种；雄性短前翅上没有发音器官，两性的前胫节两侧均没有鼓膜。我们介绍了这个新物种及其完整的线粒体基因组，并基于从下一代测序基因组快速筛选方法获得的分子数据评估系统发育关系。系统发育分析将新物种置于Xenogryllini族的属内，作为Robillard的姐妹物种。我们描述了新物种，提供了主要形态、雄性和雌性生殖器的插图、活体标本照片以及栖息地信息，并更新了该属物种的鉴定检索表。我们讨论了新物种与相关类群之间的差异以及这种蟋蟀惊人的声学通讯丧失情况。
