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 本文对1960年以柳叶状幼体（leptocephali larvae）描述的3种鳗类的分类学地位进行修订与阐明：1960年Tommasi发表的勒氏柳叶鳗（Leptocephalus anaelisae Tommasi, 1960）隶属于蚓鳗科（Moringuidae），确认为1858年Girard发表的尖吻新康吉鳗（Neoconger mucronatus Girard, 1858）的晚出同物异名（junior synonym）；1960年Tommasi发表的茱莉亚柳叶鳗（Leptocephalus juliae Tommasi, 1960）隶属于海鳝科（Muraenidae），确认为1825年Lesueur发表的斑尾鳍海鳝（Uropterygius macularius (Lesueur, 1825)）的晚出同物异名；1960年Tommasi发表的亨氏柳叶鳗（Leptocephalus humbermariorum Tommasi, 1960）隶属于康吉鳗科（Congridae），现归入吻鳗属（Rhynchoconger Jordan & Hubbs, 1925），列为疑名（species inquirenda）。上述3个物种均以唯一正模标本（holotype）作为模式标本发表，但本次调研涉及的所有科学馆藏均未发现这3份正模标本，确认为永久遗失。
