Lecithotrophic y-naupliar morphospecies (‘Types’) successfully reared during fieldwork at Sesoko Island (Okinawa) in 2018 and 2019, based on 5137 sampled lecithotrophic nauplii, with sporadic data added from earlier sampling in 1991–2005. The y-naupliar morphospecies are listed in descending order of abundance in 2018 and 2019 (column 4). Developmental time to cyprid and mean body length of last-stage nauplii (LSN) are shown, along with calculated rearing success to LSN or cyprid, degree of overlap in occurrence in both years, and correlation between morphospecies abundance and size (see Fig. 20). The data are extracted from the more comprehensive supplementary Table S1. Asterisks (e.g., Types A*, D*, E*) are added to the designations of morphospecies that exhibited molecular variation among specimens in Dreyer et al.

In lateral view, longitudinal axes of cephalon and trunk in approximately same plane (not examined). Length 340 µm (ventral view in life, without dorso-caudal spine), greatest width ca 180 µm, dorso-ventral thickness not measured but body perhaps significantly flattened. Labrum produced as triangular elevation, about as long as wide, with surface divided into facets by cuticular ridges and bearing at least four pores: two in posterior midline and additional pair of pores rather posteriorly along left and right labral margins. Caudal end broadly acute, terminating in 10 µm long dorso-caudal spine with one or two annulate ridges, this spine being flanked ventro-laterally by pair of tiny, pointed furcal spines, these being situated slightly ventral to, and forward from, base of dorso-caudal spine.</paragraph>
