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. (2023a) and might therefore represent more than one biological species." httpUri="http://table.plazi.org/id/B9C307BD0A3F1E0D3BB261DEFDED95B1" pageId="23" pageNumber="24" tableUuid="B9C307BD0A3F1E0D3BB261DEFDED95B1">Tables 1 and S1</tableCitation>

. Lecithotrophic. Body spoon-shaped in dorso-ventral view; about twice as long as wide (without dorso-caudal spine); cephalic shield broadly rounded, with sharp discontinuity in body outline leading into trunk. In lateral view, body only slightly bent, trunk axis downturned 15–20° relative to cephalic axis. Length ca 330 µm (ventral view in life, without dorso-caudal spine), greatest width 180 µm, greatest dorso-ventral thickness ca 100 µm. Labrum with goblet-shaped outline in ventral view and posterior margin free; labral surface divided into facets by cuticular ridges; midline of labrum extending ventrally as huge, cockscomb-like, spine-bearing crest. Cephalic shield with spines bordering pair of pits at postero-lateral corners. Trunk dorsum with two longitudinal rows of spines. Caudal end attenuate, terminating in 120 µm long, robust, and conical dorso-caudal spine armed with smaller spines and accompanied ventrally at base by pair of curved, 15 µm long furcal spines; dorso-caudal spine upturned 20° relative to trunk axis.
