Hypselodoris maculosa? from SE Sulawesi, Indonesia
May 2, 2002
From: Lindsey Warren
Dear Bill
This specimen was found by Dean Lea on 11 August 1999 off Karang Kaledupa.
Unfortunately no details were recorded as to depth, time of day or surface on which it was found. [Tukang Besi Archipelago, SE Sulawesi, Indonesia - Operation Wallacea]. Size: 14 mm.
The other specimens of H. maculosa we have seen feature red markings on the notum rather than simply magenta spots on the mantle margin. The overall body colour is white darkening to beige with prominent but small raised white pustules. The rhinophores are lamellate retractile, white with 3 orange bands. The gills are translucent white with orange tips. The foot has the same colouration as the mantle.
What are your thoughts on this one?
All the best

Dear Lindsay,
There are a number of species with this general colour pattern, including Hypselodoris bertschi and H. maculosa. Only H. maculosa can have the three reddish bands on the rhinophore clubs, but the white specks and faint brown lines all over the dorsum don't really fit. One possibility is the animal I have been calling Hypselodoris cf. carnea. If you have a look at the photos of animals from New South Wales you can see it can have 3 bands on the rhinophore clubs and has thin alternating brown and white longitudinal lines. If the white lines were broken into spots they would be very like this animal from Sulawesi.
But basically we would need some more material, intermediates and some anatomy before we could say anything sensible
Best wishes,
Bill Rudman
