Lipotactinae is an elusive monophyletic subfamily of katydids (Orthoptera: Tettigoniidae) unique to Asia and comprising two genera – Lipotactes and Mortoniellus. Nearly nothing is known beyond their original descriptions. The stridulum morphology is rarely examined and described in taxonomy and their acoustics are only known for six species, none of which is from Borneo. New Lipotactes specimens collected from Borneo – Belait and Kuala Belalong in Brunei and Sandakan in Sabah – were initially identified as Lipotactes alienus and/or Lipotactes virescens based on traditional morphological characters. However, the structures of male calling songs of individuals from Kuala Belalong and Sandakan were profoundly different from each other and from the known songs of L. virescens from Thailand and Peninsular Malaysia. This led us to examine the morphology of the Bornean specimens more closely. By integrating call structures, stridulum morphology, and traditional morphology, we establish that the specimens from Borneo are different from L. virescens and that the populations from Kuala Belalong, Belait, and Sandakan represent different ethospecies. Here, we describe the species from Sandakan as Lipotactes kabili sp. nov. We also demonstrate that both stridulum morphology and call structures can be useful in separating Lipotactinae species because inter-specific differences are larger than intra-specific differences. http://zoobank.org/urn:lsid:zoobank.org:pub:A81579A3-CD0A-453C-BE03-236A21544031 http://zoobank.org/urn:lsid:zoobank.org:act:B89DB3B2-4913-4A6D-9D8D-91AFC5EEDDF8

超声波生物声学和 stridulum 形态揭示了来自婆罗洲的 Lipotactes 大眼 katydids（直翅目：Tettigoniidae：Lipotactinae）中的神秘物种

Lipotactinae 是亚洲特有的一种难以捉摸的单系亚科 katydids（直翅目：Tettigoniidae），包括两个属 - Lipotactes 和 Mortoniellus。除了它们的原始描述之外，几乎一无所知。很少在分类学中检查和描述 stridulum 形态学，它们的声学仅已知六个物种，其中没有一个来自婆罗洲。从婆罗洲采集的新 Lipotactes 标本——文莱的 Belait 和 Kuala Bealong 以及沙巴的山打根——最初根据传统形态特征被确定为 Lipotactes Aliusus 和/或 Lipotactes virescens。然而，Kuala Belalong 和 Sandakan 个体的男性召唤歌曲的结构彼此之间以及与来自泰国和马来西亚半岛的 L. virescens 的已知歌曲有着深刻的不同。这导致我们更仔细地检查婆罗洲标本的形态。通过整合呼叫结构、stridulum 形态和传统形态，我们确定来自婆罗洲的标本与 L. virescens 不同，并且来自 Kuala Belalong、Belait 和 Sandakan 的种群代表不同的物种。在这里，我们将山打根的物种描述为 Lipotactes kabili sp。十一月 我们还证明了 Stridulum 形态和调用结构都可用于分离 Lipotactinae 物种，因为种间差异大于种内差异。http://zoobank.org/urn:lsid:zoobank.org:pub:A81579A3-CD0A-453C-BE03-236A21544031 http://zoobank.org/urn:lsid:zoobank.org:act:B89DB3B2-4913-4A6D -9D8D-91AFC5EEDDF8 stridulum 形态学和传统形态学，我们确定来自婆罗洲的标本与 L. virescens 不同，并且来自 Kuala Belalong、Belait 和 Sandakan 的种群代表不同的物种。在这里，我们将山打根的物种描述为 Lipotactes kabili sp。十一月 我们还证明了 Stridulum 形态和调用结构都可用于分离 Lipotactinae 物种，因为种间差异大于种内差异。http://zoobank.org/urn:lsid:zoobank.org:pub:A81579A3-CD0A-453C-BE03-236A21544031 http://zoobank.org/urn:lsid:zoobank.org:act:B89DB3B2-4913-4A6D -9D8D-91AFC5EEDDF8 stridulum 形态学和传统形态学，我们确定来自婆罗洲的标本与 L. virescens 不同，并且来自 Kuala Belalong、Belait 和 Sandakan 的种群代表不同的物种。在这里，我们将山打根的物种描述为 Lipotactes kabili sp。十一月 我们还证明了 Stridulum 形态和调用结构都可用于分离 Lipotactinae 物种，因为种间差异大于种内差异。http://zoobank.org/urn:lsid:zoobank.org:pub:A81579A3-CD0A-453C-BE03-236A21544031 http://zoobank.org/urn:lsid:zoobank.org:act:B89DB3B2-4913-4A6D -9D8D-91AFC5EEDDF8 和山打根代表不同的种族。在这里，我们将山打根的物种描述为 Lipotactes kabili sp。十一月 我们还证明了 Stridulum 形态和调用结构都可用于分离 Lipotactinae 物种，因为种间差异大于种内差异。http://zoobank.org/urn:lsid:zoobank.org:pub:A81579A3-CD0A-453C-BE03-236A21544031 http://zoobank.org/urn:lsid:zoobank.org:act:B89DB3B2-4913-4A6D -9D8D-91AFC5EEDDF8 和山打根代表不同的种族。在这里，我们将山打根的物种描述为 Lipotactes kabili sp。十一月 我们还证明了 Stridulum 形态和调用结构都可用于分离 Lipotactinae 物种，因为种间差异大于种内差异。http://zoobank.org/urn:lsid:zoobank.org:pub:A81579A3-CD0A-453C-BE03-236A21544031 http://zoobank.org/urn:lsid:zoobank.org:act:B89DB3B2-4913-4A6D -9D8D-91AFC5EEDDF8
