Aorist indicative active, third person singulars, the headword one from the verb a)mala/ptw (= a)maldu/nw, alpha 1479).
The headword might be quoted from Lycophron, Alexandra 34, a much-quoted line where the scholia offer several synonyms; however, Hesychius eta417 cites Sophocles' lost play Odysseus Mad (Soph. fr. 427).
According to LSJ s.v., bla/ptw is derived from a root beginning with *ml-, and is cognate with Sanskrit marcáyati 'injure', mṛktás 'wounded', Lat. mulco 'maltreat'. So the headword (similarly glossed in other lexica) could in fact represent an old dialectal variant of the aorist e)/blayen.
