We describe and quantify the mating behavioural sequence of Lebinthus santoensis Robillard, 2009, a cricket species from Espiritu Santo Island (Vanuatu) characterised by ultrasonic calling songs reaching 26 kHz. In trials carried out in laboratory we observed the complete mating sequence for two couples. We observed sequences of multiple copulations of short duration repeated at constant intervals, characterised by high rates of tremulation and acoustic activity, and showing an overlapping between the inter-copulation guarding and courtship. We analysed the durations of the production, transfer and retract of successive spermatophores and described the male and female behaviours during courtship and mating.
