On the taxonomic status of three eels (Teleostei: Anguilliformes) described from Leptocephali by Tommasi (1960)

ABSTRACT The taxonomic status of three species of eels described from leptocephali larvae in 1960, is revised and elucidated: Leptocephalus anaelisae Tommasi, 1960, a member of Moringuidae, is confirmed as a junior synonym of Neoconger mucronatus Girard, 1858; Leptocephalus juliae Tommasi, 1960, a Muraenidae, is confirmed as a junior synonym of Uropterygius macularius (Lesueur, 1825); and Leptocephalus humbermariorum Tommasi, 1960, a Congridae, is now placed as species inquirenda in Rhynchoconger Jordan & Hubbs, 1925. Each of the three species was described based on a unique holotype, but none of the tree holotypes were found in any scientific collection investigated by us. Indeed, the three holotypes are considered to be permanently lost.摘要 本研究对1960年基于柳叶鳗幼体（leptocephali larvae）描述的3种鳗鱼的分类学地位进行了修订与阐明：1960年Tommasi描述的Leptocephalus anaelisae隶属于蠕鳗科（Moringuidae），现被确定为Neoconger mucronatus Girard, 1858的同物异名（junior synonym）；1960年Tommasi描述的Leptocephalus juliae隶属于海鳝科（Muraenidae），现被确定为Uropterygius macularius (Lesueur, 1825)的同物异名；1960年Tommasi描述的Leptocephalus humbermariorum隶属于康吉鳗科（Congridae），现被归入吻鳗属（Rhynchoconger Jordan & Hubbs, 1925），作为疑名（species inquirenda）处理。上述3个物种均以唯一正模标本（holotype）为基础进行描述，但本研究调研的所有科学馆藏中均未发现这3份正模标本。事实上，这3份正模标本已被确认永久遗失。
