Onchidoris depressa from Tasmania

From: Bill Rudman

To accompany my message on Onchidoris depressa from New Caledonia, here are some records of this species from southern Tasmania. I thought at first that this was Acanthodoris nanega Burn, 1969 which is from the same region and is described to be very similar externally. However Burn described the radula as having 5 outer teeth, which is fairly typical of Acanthodoris whereas the radula of my specimens [see separate message] look identical to Thompson & Brown's (1984) illustration of the radula of O. depressa.
