Author Byrne, Maria Author Collins, John Author Hart, Michael W text Zootaxa 2003 359 1 14 journal article 51246 10.5281/zenodo.156371 ab7cedcc-09f7-4eb6-a3b1-c0810c06a2ad 1175­5326 156371 Cryptasterina ( Patiriella) " pseudoexigua " Chen and Chen, 1992 Synonymy : non P. pseudoexigua Dartnall Material examined : four specimens, Taiwan , coll. Chao, 2000 The pattern of flattened and closely appressed abactinal plates distinguishes this species from its mirror image congener (" P. pseudoexigua " in Australia ). In addition molecular data have supported its distinctiveness ( Hart et al. 1997 ). It is the sister species to C. pacifica (n. comb; see below and Fig. 1 ) and referred to here as Cryptasterina n.sp. Distribution : southern Taiwan (Wanlitung) ( Chen and Chen 1992 ). Reproduction and development : Planktonic lecithotroph (detailed reproductive biology studies reported in the seminal paper of Chen and Chen, 1992 )
