Abstract:Samples of Leptomedusae were collected from the upwelling area of the east Guangdong and south Fujian coast waters at 21.6°~24.3°,115.7°~118.7° on June,2009.One new species and one new record in China of Leptomedusae,i.e.Lovenella macrogona Lin,Xu et Huang,sp.nov.and Phialella fragilis(Uchida,1938) are described in the present paper.The specific diagnosis of Lovenella macrogona sp.nov.is as follows:Umbrella hemispherical,with scatted nematocysts on umbrella;four large egg-shaped gonads on the middle radial;four perradial marginal tentacles,with a black pigmented patch along the abaxial bulbs,each flanked by six to eight pairs of lateral cirri;four big interadial marginal warts,spherical shape,with excretory papillae and black pigmented patches on the abaxial bulbs;24 statocysts,each with one concretion.
Keywords:marine biology  Leptomedusae  Lovenella macrogona  Phialella fragilis  Upwelling area of east Guangdong and south Fujian coast waters  new species
