The family and genus names literally translate as
clock-stomach. Andrássy (2005) speculates that Cobb provided
the name to the genus Chronogaster because the elongate valve in
the terminal bulb resembles the hands of a clock. Alternatively, the
esophagus with terminal bulb and its elongate extension might be considered
to resemble the pendulum of a clock.
