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)
