Congermuraena Kaup [J. J.] 1856:71 Fem. Muraena balearica Delaroche 1809. Type by subsequent designation. Also in Kaup 1857:108 [ref. 2573]. Congromuraena Günther 1870:40 [ref. 1995] is an unjustified emendation. Type (as Muraena belearica De la Roche) apparently not designated by Bleeker, contrary to Jordan (1919:272 [ref. 2410]). In 1990 we regarded Ogilby 1898:284-285 [ref. 3276] as designating Congrus habenata Richardson 1844. Since 1990, we find that type designation can date to Jordan & Evermann 1896:270 [ref. 2422] and Jordan & Evermann 1896:355 [ref. 2443] as balearica, thereby preserving current usage. •Synonym of Ariosoma Swainson 1838 -- (Blache et al. 1973:240 [ref. 7185], Smith 1989:491 [ref. 13285], Zhang et al. 2010:193 [ref. 31511]). Current status: Synonym of Ariosoma Swainson 1838. Congridae: Bathymyrinae.
