The mantle seems relatively thin when compared to other species of Dermatobranchus. The underlying colour of the mantle is pale rufous beige with a darker area medially starting behind the rhinophores. On the mantle are widely spaced ridges which start from the medial line of the body and separate out further as they run to the mantle edge - the overall appearance is reminiscent of a feather or leaf. One central ridge starts between the rhinophores where the mantle edge blends into the head. Along each narrow ridge is a dark broken line and small speckles of white. The mantle edge is of a similar thickness and colour to the ridges and in some specimens has tinges of green. The elongate rhinophores are close together behind the oral veil, just in front of the beginning of the mantle; the rhinophore stalks are white with a thin yellow line down the posterior face; the vertically laminate slightly bulbous clubs have three bands - dark brown - cream - dark brown with white-tipped apices; the lamellae are edged in white. The foot does not extend beyond the mantle edge; the sides of the foot are white and covered in tiny dots of purple/red creating an overall pink tone and the edge features a thin yellow line; the oral veil has a denser covering of purple/red spots with yellow edge.
Species measured were found at night on or close to Clavularia sp. soft coral.

As regulars to the Slug Site will already know from seeing her previous contributions, Lindsay's fascination with all things aquatic began as a small child and this has carried on throughout her life. However, it was only when at university that she discovered that diving was not just the prerogative of the elite. Beginning in 1974 with her first OW dive in 1975 near Marseilles, France, she noted in her logbook finding a nudibranch but had no idea what it was at the time. However many years later she was happily able to identify it.
On the photographic front, the only reason she ever took it up was purely to document what she saw when diving. She started with a second-hand Nikonos II, then a Nikonos III and later progressed to a Nikon F3 in an Aquatica housing. However, she became an accomplished photographer of land & air wildlife as well as human life events, capturing special moments. And yet still her first love remains with molluscs.
Having dived in many areas of the world including the UK, the Mediterranean, (Spain, France, Corsica), Red Sea (Israel & Egypt), Bahamas, USA (Florida, California, Hawaii), St Lucia, Montserrat, South Africa, Madagascar, Brazil, Fiji, Tonga, French Polynesia, the Tukang Besi Archipelago (SE Sulawesi, Indonesia), Lindsay now spends most of her time in Indonesia diving in places such as Bali, Alor, Lembeh as well as Sangeang, Komodo, Flores, Sumbawa, but also in the species rich Philippines.
Lindsay was a prolific contributor to Bill Rudman's Sea Slug Forum when it was still an active site but she continues to look for and photograph opisthobranchs of all kinds sharing her finds with us via facebook, contributions to ebooks and id apps as well as direct with taxonomists around the world.
