Likewise or similarly in other lexica: see the references at Photius nu133 Theodoridis. The earliest of them, Hesychius nu329, has dative singular, otherwise attested only in late epic (Quintus 7.29), but if the Suda's neo/kmhton is actually quoted from somewhere the likeliest option is Euripides, Rhesus 887 (a variant reading there for neo/dmhtos [cf. nu 185] with the meaning "new-slain").
