FIGURE 87–96. Navicula cryptocephala strain LCR-S:32:1, CHR618415. Scales: Fig. 87, 10 µm (use for Figs 87, 88); Fig. 89, 5 µm (use for Figs 89–93); all others 1 µm. Figs 87, 88. Live cells viewed by LM, showing paired parietal plastids close against valve margins. Figs 89–93. Cleaned frustules viewed by LM (girdle view in Fig. 93, showing curved valve faces). Figs 94–96. SEM of cleaned frustules. Fig. 94, whole frustule, showing elongated, longitudinally aligned areolae; Fig. 95, widened central area showing central raphe termini; Fig. 96, valve apex showing hooked raphe terminus and pattern of areolae.Published as part of Novis, Phil M., Braidwood, Jasmine & Kilroy, Cathy, 2012, Small diatoms (Bacillariophyta) in cultures from the Styx River, New Zealand, including descriptions of three new species, pp. 11-45 in Phytotaxa 64 (1) on page 30, DOI: 10.11646/phytotaxa.64.1.3, http://zenodo.org/record/506200
