arenata, Thyrsoidea Kaup [J. J.] 1856:61 [Archiv für Naturgeschichte v. 22 (pt. 1); ref. 2572] China. Holotype: BMNH uncat. (651 mm TL). Type catalog: Böhlke & Smith 2002:94 [ref. 26380]. Also in Kaup 1856:85 [ref. 2573]. Probably should be regarded as an unneeded replacement name for Muraena thyrsoidea Richardson 1845, based on a Cuvier museum name, with type the Richardson specimen. Kaup's description probably possibly based on MNHN A.8810 from Pondicherry, which Böhlke & Smith 2002:94 [ref. 26380] regard as the tentative holotype of arenata. •Objective synonym of Siderea thyrsoidea Richardson 1845 -- (Böhlke 1995:463 [ref. 21738]). •Synonym of Gymnothorax thyrsoideus (Richardson 1845) -- (Böhlke & Smith 2002:94 [ref. 26380] as thysoidea and thysoideus, Smith 2012:28 [ref. 32155]). Replacement Name. Current status: Synonym of Gymnothorax thyrsoideus (Richardson 1845). Muraenidae: Muraeninae. Habitat: marine.
