MALE: always macropterous (even if the female is micropterous); palpal ratio: 6/3; forewing usually with distal part of stigmal vein longer than proximal part, less frequently as long as, or shorter than proximal part; forewing usually with pterostigma four or more than four times as long as broad; antennal hairs usually much longer than breadth of segments, less frequently shorter than breadth of segments; vertex of head frequently with two strong oblique keels connecting the posterior ocelli to the occipital carina; parameres without dorsal process, usually with more or less large inner branch wrapping penis, less frequently with reduced inner branch; tibial spurs 1, 1, 2.
