Remarks.

Notomastus tenuis was described from California by Moore (1909). Fauchald (1972) reported it from Baja California, Baja California Sur, Nayarit and Jalisco while Hernández-Alcántara and Solís-Weiss (1998) reported it from the Gulf of California. Examination of specimens of both author's collections indicated that they were actually Notomastus hemipodus Hartman, 1945. The report by Calderón-Aguilera and Jorajuria-Corbo (1986) for San Quintín Bay seems to be incorrect, as the description and illustrations do not correspond to Notomastus tenuis . The records of Notomastus tenuis from western of México are therefore considered doubtful.
