Chromodoris annae (left) and Chromodoris cf. strigata (right).

Comment from Richard Willan on photo #955
It is definitely not Chromodoris elisabethina because it has a white marginal band, which makes it either Chromodoris annae or Chromodoris magnifica. I choose Chromodoris annae because of the black peppered pattern on the blue areas of the mantle.

Comment from Richard Willan on photo #32
A colour form with a white marginal band, but the black speckles on the mantle are distinctive.

Yes; this tropical species (plus the temperate Western Australian endemic species Chromodoris westraliensis) has the black pores all over the mantle which gives immediate identification.

Note the numerous black speckles like pepper on the blue central area of the mantle.

Comment from Richard Willan on photo #768
An atypical specimen that has wider than normal white bands either side of the orange band. However the conspicuous glandular pores that look like sprinkled pepper on the central (pale blue) section of the mantle that characterise this species are perfectly discernible.

Both have elongated bodyform, both have yellowish or orange-ish gills and rhinophones, both have similar mantle colouration and colour variation - pale to bright blue in the middle with black elongated lines bordering the blue area, and faded to bright orange mantle margin.

Chromodoris elisabethina normally has more elongated black lines in the blue area, sometimes a median line, often some broken shorter lines.

Chromodoris annae usually has no or less black lines, but some have been found to have multi black lines like Chromodoris elisabethina.

So what's the telltale difference? Apparently it's the uniformity of the blue colour. If it's smooth and uniformly coloured then it's Chromodoris elisabethina, while if the blue area has tiny dark speckles hence not uniform (zoom your photos to see it!) then it's Chromodoris annae.
