Description
Central mantle pale yellow to deep yellow-brown, surrounded by a broad white band carrying a row of bright red round spots, then a wider, deeper-yellow submarginal band, with a narrow white line at the very edge. Rhinophore stalk translucent orange; club dark orange-brown with white anterior and posterior midlines and a white tip. Gills white with translucent yellow-brown lamellae. The mantle skirt is rhythmically lifted while crawling. Reaches 41 mm in body length.Distribution
Type locality is Osprey Island, Rocky Point, North Queensland, Australia (collected in 1979). The original description (Rudman, 1986) is based on northern Queensland material; subsequent records extend to Indonesia, Papua New Guinea, the Philippines, the Solomon Islands, and Japan.Etymology
The specific epithet cruentus is Latin for stained with blood or spotted with blood, referring to the bright red spots on the mantle.Remarks
Originally described as Glossodoris cruentus and later transferred to Ardeadoris. Closely resembles Ardeadoris rubroannulata but is distinguished by having discrete red spots inside the white submarginal band, whereas Ardeadoris rubroannulata has a continuous red line on the outside of the white band.References
