One of the many Suda entries which differentiate between two verb forms with very similar spelling. In the present instance they are probably both extracted from Sophocles: Oedipus at Colonus 72 and Oedipus Tyrannus 889, respectively.
The entry also illustrates that kerdai/nw in Attic, being a liquid verb, takes an apparently non-sigmatic aorist and future (kerdan-). Later Greek used the sigmatic stem kerdhs- instead, which presumably is why kappa 1384 was introduced as a gloss.
Properly the adjective au)qupo/taktos refers to the second aorist, but it can also refer to the first aorist, especially in the case of liquid verbs (LSJ s.v.); e.g. delta 655, pi 1031.
