fortil, however, in general, the cells are shorter, less asymmetrical in relation to the longitudinal axis of the cell, and the base of R3 is usually located further from the antapex, at the distance of 3/5-213 of the cell length, while in D.
Cell bodies are suboval, symmetrical in relation to their longitudinal and latitudinal axes, with narrowly rounded antapex.
However, the latter is different in having (1) a narrower rounded posterior end of the cell body, (2) a posterior rib (R3) emerging from the antapex, (3) the absence of ribs other than R3, and (4) a strongly reticulated LSL.
