Abstract
Odontacarus robbinsi n. sp. is described from larvae taken off Sceloponis orcutti licki from 3.2 km S San Antonio, Baja California Sur, Mexico, and additional larvae were from Sceloponis magister zosteromus, and Uroscmnis nigricaiidus of the cape region. This species closely resembles Odontacarus cayolargoensis Brennan, 1959.
