κλύω as a present verb

I was wondering if anyone knew of the earliest attestation of κλύω ‘hear’ as a present.
The original verb is a root aorist (thematic κλύον/ἔκλυον = Skt. śruvam, innovated from a still older athematic aorist, as in imperative κλῦθι = Skt. śrudhi - Sanskrit seems to have gone through the same development independently), from the PIE root *ḱleu-; but a present κλύω was built on it in the same way that for instance κίω ‘go’ was founded on aorist κίον/ἔκιον or ἠμί ‘say’ on ἦ (‘said he’).
I’m just trying to determine if unambiguously present forms already occur in Homer, or, if not, when and in what author(s).

According to the entry on κλυεῖν, κλὐω in the Necronomic… um I mean the Lexikon des Frühgriechischen Epos, the only attestation in Early Epic of the present is Hesiod’s Work and Days line 726 οὐ γὰρ τοί γε κλύουσιν, ἀποπτύουσι δέ τ᾽ ἀράς.

So that must be the earliest attestation.

Thank you very much! That’s exactly what I was looking for.

As you probably now, it’s a subject of debate whether Homer or Hesiod is earlier. “Traditionally” Homer is the oldest, but M.L. West was among those who considered Hesiod earlier.
