Sphenomorphus capitolythos is a species of skink, a lizard in the subfamily Sphenomorphinae of the family Scincidae.

[2] The specific name, capitolythos, is in honor of Austrian herpetologist Felix Kopstein through a trilingual play on words.

Kopf + Stein in German, meaning "head + stone" in English, becomes capito + lythos in Greek.

[3] Medium-sized for its genus, S. capitolythos may attain a snout-to-vent length (SVL) of about 8 cm (3.1 in).

[2] The preferred natural habitat of S. capitolythos is forest.
