Description
FIGURES 41–46. Gomphonema lepskayae sp. nov., SEM, slide no. 09862 from sample O-1, type material. 41, 43. The entire valve, externally. Proximal raphe ends expanded and dislocated towards the stigmoid (black arrows), distal raphe fissures unilaterally curved (white arrows). Note the stigmoid with a round external opening (black arrowheads). 42, 44. The entire valve, internally. Proximal raphe ends hook-shaped (black arrows), distal raphe fissures terminating with helictoglossae (white arrows). Note the round internal opening of the stigmoid (black arrowheads). 45. Valve footpole, externally. Distal raphe fissure (black arrow) bisects the APF with round porelli (white arrows). Note the C-shaped areolae (black arrowheads). 46. Valve footpole, internally. Distal raphe fissure terminates with helictoglossa (white arrow), APF comprised of porelli covered by lenticular occlusions (black arrows). Note the unilateral foricula occluding the areolae (black arrowheads) and the pseudoseptum (asterisk). 47. Central valve part, internally. Proximal raphe ends hook-shaped (black arrows), dislocated towards the inner opening of the stigmoid (black arrowhead). Note the vimines separating the areolae (white arrows). Scale bars = 2 µm (Figs 41–44), 1 µm (Fig. 45), 0.5 µm (Figs 46–47).
