Amblyopsidae) in the genus Amblyopsis from subterranean habitats of southern Indiana, USA. The Hoosier Cavefish, Amblyopsis hoosieri sp. n., is distinguished from A. spelaea, its only congener, based on genetic, geographic, and morphological evidence. Several morphological features distinguish the new species, including a much plumper, Bibendum-like wrinkled body with rounded fins, and the absence of a premature stop codon in the gene rhodopsin. This is the first new cavefish species described from the United States in 40 years and exemplifies how molecular data can alert us to the presence of otherwise cryptic biodiversity.
来自美国印第安纳州南部地下栖息地的盲鮰科（Amblyopsidae）盲鮰属（Amblyopsis）鱼类。霍西洞穴鱼（Amblyopsis hoosieri sp. n.），根据遗传、地理和形态学证据，与其唯一的同属物种洞穴盲鮰（A. spelaea）相区分。几个形态特征区分了这个新物种，包括一个更丰满、类似米其林轮胎人的有皱纹的身体和圆形的鳍，以及视紫红质基因中不存在过早的终止密码子。这是40年来首次从美国描述的新洞穴鱼物种，例证了分子数据如何能提醒我们注意到其他隐藏的生物多样性的存在。
