Pseudoceros scintillatus is a small species which measures around 9 mm.
The dorsal pattern, without a longitudinal center line, is velvety black with a bold pattern of large green-yellow spots of irregular size and a wide orange border. Each spot, surrounded by a white ring, extends into the marginal band.
The pseudo-tentacles are simple folds.
The vas deferens is not branched. The seminal vesicle is small, oval and rounded. The prostate is rounded, small and oval. The stylet is relatively short, slightly longer than the prostate. The male and female antrum are shallow.
