[1] The headword is perfect middle/passive participle of e)paine/w (irregularly reduplicated) in the genitive plural. It must be quoted from somewhere: not, as transmitted, from the quotation which follows, but see next note. Compare generally epsilon 2007, epsilon 2008, epsilon 2009, epsilon 2010, epsilon 2187, epsilon 2188.
[2] Aelian fr. 81a Domingo-Forasté (78 Hercher). As transmitted here the participle is in the dative singular, but editors of Aelian (not, however, D-F) and others change it to the genitive plural, thus producing the meaning "... much greater pay should be procured from those who had been praised."
