Millerichthys robustus is the only annual cynolebiid species in Mexico. The purpose of the present study is to describe patterns of reproductive behaviour in this species. Seven individual units of behaviour were identified in males and five in females, some of which exhibit differences that can be interpreted as specifically derived conditions. In Millerichthys robustus, the phase of invitation to submerge/dive was not initiated by the male, but by the female.
