A putative stridulatory apparatus on the mouth- parts of cylindrachetids was described and figured by G ̧nther (1992) and Rentz (1996). It consists of a field of microscopic tubercles arranged in rows on the ventral surface of each mandible and a single row of about seven short ridges on the opposing dorsal surface of the basal segment of each maxillary palpus. G ̧nther noted this apparatus in both sexes. It is now clear that it occurs in all nymphal instars as well. Thus, it is unlikely that the apparatus plays a part in mate-attraction, if in fact it produces sound at all. I detected no stridulatory sounds from sandgropers, even when holding them close to my ear.
