Neocalyptrella robusta — Hernández-Becerril and Meave del Castillo (1996); Hernández-Becerril and Maeve del Castillo (1997): 329; Hasle and Syvertsen (1997); Sunesen and Sar (2007); Hoppenrath et al. (2009); Yun and Lee (2011); Boonprakob et al. (2021); Guiry and Guiry (2025).
Description
Cells in valvar cross section elliptical; cells in girdle view sigmoid, curved and crescent-shaped. Length 227–240 (in culture) to 477 (500–1000) µm, diameter 59 (109, in culture) (40–400) µm. Valves noticeably conical, with longitudinal undulations converging near truncated apex. Valve apex has calyptra, which bears a needle-like external tube or process that is a complex rimportula. Valve areolae 13–20 in 10 µm arranged in regular, straight striations and with secondary quincunx pattern of 22–25 in 10 µm.
Notes
The morphology of these LM images agrees with literature, especially the images and description in Sunesen and Sar (2007). Only observed in December. Rare in Galiano Island waters. iNaturalist ID: 48460936 (Fig. 28).
