Resumen:
The instar III larva of Liocanthydrus clayae (J. Balfour-Browne, 1969) is described and illustrated, including morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment, and urogomphus. Larvae of Liocanthydrus Guignot, 1957, can be readily separated from other known noterid larvae by the presence of two short posterodorsal projections on the last abdominal segment. Regarding chaetotaxy, Liocanthydrus differs from Suphis Aubé, 1836, Hydrocanthus Say, 1823 and Suphisellus Crotch, 1873 in the position of seta AN7, the shape of seta CO13, the shape and length of setae FE6 and TI7, and the length of seta UR8.
