Type species. Deinodryinus paradoxus R. Perkins, 1907, designated by Muesebeck & Walkley, 1951.

Diagnosis. Female (Plate 54A): macropterous (Plate 54A), or micropterous (not present in the Oriental region); palpal formula 6/3; occipital carina complete; vertex of head frequently with two strong oblique keels connecting posterior ocelli to occipital carina; pronotum with distinct anterior collar and posterior disc (Plate 54A); in macropterous females fore wing usually with distal part of stigmal vein longer than proximal part (as in plate 55A), less frequently as long as, or shorter than proximal part (Plate 54A); enlarged claw with inner proximal prominence not bearing bristles (Plates 54B, 56C, 57D), with one–two bristles or peg-like hairs located further distally than proximal prominence (Plates 54B, 56C, 57D); tibial spurs 1/1/2. Male (Plate 55A, B): always macropterous (even with female micropterous) (Plate 55A, B); palpal formula 6/3; vertex of head frequently with two strong oblique keels connecting posterior ocelli to occipital carina (Plate 55A); antennal hairs usually much longer than breadth of segments (Plate 55A), less frequently shorter than breadth of segments; fore wing usually with distal part of stigmal vein longer than proximal part (Plate 55A, B), less frequently as long as, or shorter than proximal part; fore wing usually with pterostigma four or more than four times as long as broad; paramere without dorsal process, usually with one more or less large inner branch wrapping penis (Plate 56D – F, 57A, B), less frequently with one reduced inner branch (Plate 57C); tibial spurs 1/1/2.

Distribution. Worlwide.

Hosts. Cicadellidae ( Guglielmino & Olmi, 2006, 2007).

World species. One hundred and fifty four species are known, nine in the Oriental region.

Remarks. Fossil species of Deinodryinus were described by Guglielmino & Olmi (2011).
