Ground colour of the notum is pink overlaid by light brown flecks which partly obscure white Y on head. Cerata are flattened, broader at the base and curved inwards; the primary feature for identification (L. Carmona, pers. comm. 7 October 2022).
Dense white, flecks conceal much of pinkish brown digestive gland in cerata.
