'Montereina' coerulescens is characterized by its mottled whitish-tan mantle with irregular greyish patches. It has elevated rhinophoral sheaths, and yellowish-tan rhinophores. Distinctive are minute opaque white spots at the mantle margin. The gills are translucent or translucent tan with whitish tips (in this picture and in 6 out of 9 pictures at the internet are the gills retracted).
This species is also known as Discodoris coerulescens Bergh, 1888, Dayrat (2010) restricted the genus Discodoris  Bergh, 1877
Discodoris boholiensis  Bergh, 1877, Discodoris cebuensis  Bergh, 1877, and some undescribed species and moved Discodoris coerulescens Bergh, 1888
to the provisional genus ‘Montereina’  MacFarland, 1905.
