目前全世界已知的螻蛄蝦科約有139種,且98.6%的種類都是產於淺海並棲息在水深200公尺以上的海域。東北亞地區目前共僅記錄有13種螻蛄蝦,而臺灣則只知有四種螻蛄蝦分布於潮間帶的沙泥灘,本研究於臺灣東港漁港水深超過200公尺的拖網漁獲中發現一新種螻蛄蝦,並命名為Upogebia edetata sp. nov.。這種螻蛄蝦可容易地以額角側突較小和修長的腹部與臺灣其他螻蛄蝦種類分辨出,而其較長的額角和第六腹節之特徵則與其他海域的U. fallax、U. contigua及U. gracilis的形態較為相近,但其額角與頭胸甲側脊均無刺,則與上述三者明顯區別出。本文除詳細描述此新種的形態特徵外,亦提供其彩色標本照。
An Upogebia specimen collected from deep water off southern Taiwan is described as a new species, Upogebia edentata sp. nov.. The new species closely resembles U. fallax de Man, 1905; U. contigua Bozic and de Saint Laurent, 1972; and U. gracilis Ngoc-Ho, 1990, in its long rostrum and the shape of the 6th abdominal somite. However, it differs from these species by having both the rostrum and the lateral ridges of the carapace unarmed. Color figures of the new species are presented.
