1

All measurements (n = 21) are given in micrometres. Minimum and maximum values are provided, followed in parentheses by the arithmetic mean and standard deviation.

2

NDR = nucleus displacement ratio according to Bennett and Campbell (1972).

3

Microgametocyte nuclei were markedly diffuse and difficult to measure.

4

Pigment granules were difficult to calculate because they were masked by densely stained volutin.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
