Four new species and two new records Sminthea apicigastrica Xu, Huang et Du, sp. Nov., Codonorchis calcariformis Xu, Huang et Guo, sp. Nov., Aequorea nanhainensis Xu, Huang et Du, sp. Nov., A. tetranema Xu, Huang et Du, sp. Nov., Paragotoea bathybia Kramp, 1942 and Zanclea medusopolypata Boreo, Bouillon et Gravili, 2000, are described in this paper. The types are deposited in the South China Sea Fisheries Research Institute, Chinese Academy of Fishery Science.Sminthea apicigastrica Xu, Huang et Du, sp. Nov., Paragotoea bathybia Kramp,1942 and Zandea medusopolypata Boreo,Bouillon et Gravifi, 2000, are described in this paper. The types are deposited in the South China Sea Fisheries Research Institute, Chinese Academy of Fishery Science.Sminthea apicigastricaXu, Huang et Du, sp. nov. （Figs. 1-3, 11-13） Until only one species is known in genus Sminthea Gegenbaur, 1857. This new species is distinguished from Sminthea eurygaster Gegenbaur, 1857 by： 1 ） umbrella conical bell-shaped, with a high and round apical projection; 2） manubrittm short, about 2/3 the length within subumbrellar cavity of apical projection; 3 ） 8 perradial tentades are each flanked by a pair of gelatinous papillae. Holotype （SN001）, Northern of South China Sea E8 Station （21°48′N, 116°53′E）, depth 145 m, 18 Oct. 2006, HUANG Zi-Rong （SFR）. Paratype （SN002）, Northern of South China Sea Station G9 Station （20°13′N, 114°51′E）, depth 183 m, 16 Oct. 2006,HUANG Zi-Rong （SFR）. Etymology. Apicigastrica, Latin. means apical gaster. The species name refers to position of manubrium within subumbrellar cavity of apical projection.Codonorchis calcariformis Xu, Huang et Guo, sp. nov. （Figs. 4, 14-15） At present time, 3 species are known in genus Codonorchis Haeckel, 1879. This new species is dosed to Codonorchis nanhainensis Xu, Huang et Guo, 2008, but differs from them by： 1 ） adradial gonads elliptical- shaped, about 2/3 the length of manubrium; 2 ） 4 perradial marginal bulbs all with a short abaxi
