Phyllidiella pustulosa has similarities in appearance to Phylidiella annulata , Phylidiella zeylanica, Phylidiella granulata, Phyllidopsis burni, Phyllidiella nigra and Phyllidiella cooraburrama
But Phylidiella annulata differs in having many pink rings with low angular tubercles, in lacking a pale edge to the mantle and in the possession of 17-20 lamellae on each rhinophoral clavus (specimens greater than 23 mm).
But Phylidiella zeylanica has pink compound tubercles which are coalesced into longitudinal ridges ( not clusters) and black longitudinal lines.
But Phylidiella granulata has three median groups of tubercles but differs from P. pustulosa in that the tubercles are acute, multi-compound and white with grey bases, a granular grey mantle edge and 17-20 lamellae on each rhinophoral clavus.
But Phyllidopsis burni has multiple tips tubercles.
But Phyllidiella nigra is black at the mantle edge and the tubercles are usually single, quite high and evenly distributed (not clustered) over the dorsum.
But Phyllidiella cooraburrama has usually single, tall, multicompound and quite pointed tubercles
