众所周知，夏威夷群岛拥有丰富多样的轮状动物(专有的地下物种)。迄今为止，在夏威夷各主要岛屿上发现了74种专有的海绵状节肢动物物种，其中大部分来自夏威夷ʻI岛，大部分来自基拉韦厄火山的熔岩管，基拉韦厄火山是该岛最年轻的火山。最近对莫纳罗亚火山西南侧的Kipuka Kanohina熔岩管系统进行的生物清查显示，存在以前未知的适应洞穴的物种。其中，首次发现的洞穴适应种为飞虱属Iolania、Iolania frkanstoneiHoch和Porter sp.11月形态和分子数据表明，该物种与夏威夷ʻI岛的表层环境中的赤眼莲(Iolania Perkinsi)密切相关。因此，假定了近岸物种形成，进一步证实了适应性转变是年轻海洋岛屿上轮虫进化的主要进化模式这一假设。
The Hawaiian Islands are known to harbour a rich and diverse fauna of troglobionts (obligate subterranean species). To date, 74 obligate cavernicolous arthropod species have been documented from across the main Hawaiian islands, the majority of which were from Hawaiʻi Island, and mostly from lava tubes of Kilauea volcano, the youngest volcano on the island. A recent bioinventory of the Kipuka Kanohina lava tube system on the south-western side of Mauna Loa volcano revealed the existence of previously unknown cave-adapted species. Among them is the first cave-adapted species of the planthopper genusIolania,Iolania frankanstoneiHoch & Porter sp. nov. Morphological and molecular data suggest that the species is closely related to the epigean (i.e. surface-dwelling) speciesIolania perkinsi, which occurs in surface environments on Hawaiʻi Island. Thus, parapatric speciation is assumed, further corroborating the assumption that adaptive shifts are the major evolutionary patterns underlying the evolution of troglobionts on young oceanic islands.
