Parastrombidinopsis minima Tsai et al., 2008 and comparison with related species ( Table 3)

Parastrombidinopsis minima was originally report- ed by Tsai et al. (2008) based on a Taiwan population. The Haikou population matches the original description in all characteristics, except some population-dependent differences: a slightly larger cell size (67–83 × 55–75 μm vs. 43–71 × 23–42 μm in the original population after protargol staining), accompanied by higher numbers of collar membranelles (16–18 vs. 12–16) and dikinetids in each somatic kinety (14–15 vs. 11–13). In addition, the large empty vacuole which was described in the posterior cell end of the original population, was not detected in the present population. We thought those differences should be population-dependent, therefore, the Haikou population is in fact conspecific to Parastrombidinopsis minima Tsai et al., 2008 .
