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.

Body narrowly ovate, almost lanceolate in dorso-ventral view; about 1.8 times as long as wide; lateral margins without marked discontinuity in body outline between cephalic shield and trunk. In lateral view, trunk axis downturned 20° with respect to cephalic axis. Length 270–290 µm (of short form, see below) (without dorso-caudal spine), greatest width ca 150 µm, greatest dorso-ventral thickness ca 100 µm. Labrum produced as nearly equilateral sub-triangular elevation; divided into facets by cuticular ridges; pore pattern not examined in detail but three pores present in midline. Caudal end attenuate, terminating in ca 50–60 µm long, basally annulate but essentially smooth dorso-caudal spine, this being bent slightly upwards (5°) with respect to trunk axis and accompanied ventrally by pair of small, pointed furcal spines ca 6–7 µm long.</paragraph>
