Remarks :

Identification confirmed by Nathalie Yonow
    Synonymous : (according Worms)
          - Hoplodoris estrelyado Gosliner & behrens, 1998

Bibliographic data :

The body is oval and flat, the notal surface covered with large tapering tubercles which lack spicules that project from the tubercles.
    The size of the white egg-like ring becomes smaller on the tubercles nearer the margin.
    The tubercles forming the 6-8 largest fried-egg patterns are each encircled by 8-10 smaller white tubercles.
    A few tan colored tubercles are dispersed about the notal surface, and are particularly abundant near the center of the notum.
    The underside of the foot and mantle are speckled with dark brown.
    The anus is situated within the gill circle.
    This species is found on the outer edges of rock walls and reef fronts in 5-30 m of water.
    Etymology. The trivial name "estrelyado" is the Tagalog word for “sunny side up” which is derived from the Spanish word “estrella” for star, indicating the eggs are formed into starlike patterns with the yolk shining upwards. This applied to the unique pattern on the notal
