摘要

背景东太平洋有七种雷莫拉物种，其中短鳍雷莫拉在墨西哥南太平洋尚未得到证实。目标。本说明的目的是报告特万特佩克湾上存在短吻R.brachyptera。方法。该标本于2013年5月在瓦哈卡州特万特佩克湾的运动鱼活动中采集。后果该物种的头盘和源自臀鳍上方的背鳍有17层，背鳍有27条鳐鱼，胸鳍有23条鳐鱼、头盘长度32.6%标准长度和截尾。结论。这是在特万特佩克湾首次记录到短吻R.brachyptera。

First record of the spearfish remora Remora brachyptera (Carangiformes: Echeneidae) in the Gulf of Tehuantepec, Mexico

Background. Seven remora species are described for the Eastern Pacific, of them Remora brachyptera has not been confirmed in South Mexican Pacific. Goals. The aim of this note is to report the presence of R. brachyptera on the Gulf of Tehuantepec. Methods. The specimen was collected during sportfish activities in May 2013 in the Gulf of Tehuantepec, Oaxaca. Results. This species was identified by having 17 laminae in the cephalic disc and the dorsal fin that originates above the anal fin, dorsal fin with 27 rays, pectoral fin with 23 rays, cephalic disc length 32.6% standard length, and truncated tail. Conclusions. This is first record of R. brachyptera in the Gulf of Tehuantepec.
