Type species: Zancleopsis dichotoma ( Mayer, 1900) .

Medusae with or without apical projection; either with two long opposed, capitate tentacles with capitate side branches and two opposed shorter or longer, simple capitate tentacles, or with four simple capitate tentacles; marginal tentacular bulbs clasping umbrella margin, with four or two large hemispherical adaxial expansion covered with cnidocysts; manubrium flask-shaped; mouth more or less cruciform, with or without simple lips; gonads interradial, with deep interradial grooves which may divide them into 8 adradial masses; with ocelli.

Remarks. The type species, Zancleopsis dichotoma , is originally described from Tortugas, Florida by Mayer (1900) under the genus Gemmaria .

This genus is distinguished from Zanclea by the absence of exumbrellar cnidocyst pouches or track, the capitate lateral branches upon the tentacles and ocelli present, which are unknown in Zanclea .

The genus comprises the following species: Z. dichotoma ( Mayer, 1900) , Z. elegans Bouillon, 1978 , Z. gotoi ( Uchida, 1927 as Cnidotiara ), Z. symmetrica Bouillon, 1985 , Z. tentaculata Kramp, 1928 and Z. oblongus sp. nov. In China Sea, only two species are known.
