ABSTRACT Transparency is a greatly advantageous form of camouflage, allowing species to passively avoid detection regardless of the properties of the surface which they occupy. However, it is uncommon and poorly understood in terrestrial species. In one tribe of predacious katydids (Phlugidini), transparency is paired with highly ultrasonic communication for increased predator evasion, yet little is known about the singing capabilities of these species, with only one genus of Phlugidini acoustically well described to date. Here, we describe Speculophlugis hishquten; a new monotypicgenus of highly transparent crystal katy did here named after the infamous Hish-Qu-Ten from the Predator film franchise, discussing the potential use of this species for non-invasive studies of internal anatomy, and analysing its ultrasonic call. Using laser Doppler vibrometry and light microscopy techniques, we found the transparency of the cuticle around the hearing apparatus to be 85–87% at the wavelength of the laser beam (633 nm), making S. hishquten a candidate for the highest recorded cuticle transparency of any insect. The male song has a fundamental frequency of 50 kHz, matching both the ultrasonic call range and rapid call structure of other Phlugidini species. However, the extent of ultrasonic communication and the level of transparency across the Phlugidini tribe requires more attention.

对来自安第斯云雾林的新描述的高度透明的掠食性 katydids 属的生物声学和生物物理分析（直翅目：Tettigoniidae：Meconematinae：Phlugidini）

摘要 透明是一种非常有利的伪装形式，它允许物种被动地避免被发现，而不管它们占据的表面的特性如何。然而，它在陆生物种中并不常见且知之甚少。在一个掠食性 katydids (Phlugidini) 部落中，透明度与高度超声波通信相结合以增加捕食者逃避，但对这些物种的歌唱能力知之甚少，迄今为止只有一个 Phlugidini 属在声学上得到很好的描述。在这里，我们描述了 Speculophlugis hishquten；一种新的高度透明的水晶 katy 单型属在这里以臭名昭著的“捕食者”电影特许经营权中的 Hish-Qu-Ten 命名，讨论了该物种对内部解剖学的非侵入性研究的潜在用途，并分析了它的超声波呼叫。使用激光多普勒振动测量法和光学显微镜技术，我们发现在激光束波长 (633 nm) 下，听力仪器周围的角质层透明度为 85-87%，使 S. hishquten 成为记录的最高角质层透明度的候选者任何昆虫。雄性歌曲的基频为 50 kHz，与其他 Phlugidini 物种的超声波呼叫范围和快速呼叫结构相匹配。然而，超声波通信的范围和整个 Phlugidini 部落的透明度需要更多的关注。雄性歌曲的基频为 50 kHz，与其他 Phlugidini 物种的超声波呼叫范围和快速呼叫结构相匹配。然而，超声波通信的范围和整个 Phlugidini 部落的透明度需要更多的关注。雄性歌曲的基频为 50 kHz，与其他 Phlugidini 物种的超声波呼叫范围和快速呼叫结构相匹配。然而，超声波通信的范围和整个 Phlugidini 部落的透明度需要更多的关注。
