Resumen:
In semi-terrestrial crabs the production of sounds has been recognized to be related to courtship communication dynamics. The present study aims to assess if the crab Neohelice granulata (Varunidae) is able to emit acoustic signals and eventually their role in the mating behaviours. The study was divided into two different experimental conditions: ?Solitary Experiment? (consisting of three different layouts with male, unreceptive and receptive females alone) and ?Group Experiment? (consisting of mixed combinations layouts of males, unreceptive and receptive females). Synchronized acoustic and video monitoring systems were used to record the acoustic signals and locomotor behaviours of alone and grouped specimens. N. granulata produced two distinct signals, a multi-pulse rasp signal (highest numbers were recorded in layouts with male alone and with 2 males plus 1 receptive female) and a single rasp signal. These results may suggest that males use the multi-rasp signal to advertise their presence to other males or to attract receptive females. Moreover, the greatest values of locomotor behavioural parameters were observed in layouts with receptive females alone and with 2 males plus 1 receptive female, probably related to courtship behaviour.
