Dyction Walckenaer, 1837 = Megamyrmaekion Reuss, 1834 (Simon, 1882b: 257)

Gen. Megamyrmaekion Reuss, 1834 urn:lsid:nmbe.ch:spidergen:02447

type Megamyrmaekion caudatum Reuss, 1834; gender neuter

N.B.: other spellings (such as Megamyrmecion and Megamyrmecium) are unjustified emendations; considered a senior synonym of Dyction Walckenaer, 1837: 380 [urn:lsid:nmbe.ch:spidergen:06292] (type D. reuss Walckenaer, 1837 = Megamyrmaekion caudatum Reuss, 1834) by Simon, 1882b: 257; species from outside the Mediterranean are probably misplaced, per Murphy, 2007: 55.
