3.2. Subfamily Megalyrinae Schletterer, 1889

Emended diagnosis.

Head globular; compound eye oval, with or without postocular carina; flagellomeres often elongate, sometimes compact; subantennal groove with or without dorsal carina, mandibles symmetrical with three teeth. Anterior thoracic spiracle fully surrounded by pronotal cuticle; median mesoscutal sulcus sometimes effaced or reduced; parapsidal lines sometimes absent. Fore wing with infumate banding patterns in Ettchellsia, Dinapsis, Megalyra and Megalyridia; at least Sc+R, Rs+M, basal segment of Rs and basal segment of R1 pigmented and no closed cell; at most with C, Sc+R, A, cu-a, Rs+M, Rs, R1 and basal segment of M pigmented, costal, submarginal, and marginal cells closed by tubular veins, subcostal and first cubital fused; M+Cu usually absent except in † Cretodinapsis; rarely brachypterous. Hind leg without row of erect setae along margin. Metasoma usually elongate but sometimes distinctly shorter than mesosoma.

Albian to present.

Comments.

We redefine the subfamily Megalyrinae, according to the results of the phylogenetic analyses. The subfamily is composed of three non-monotypic tribes, namely Cryptalyrini, Dinapsini, and Megalyrini, as well as a number of monotypic tribes: Rigelini, † Kamyristini trib. nov., † Megallicini trib. nov., † Valaaini trib. nov., and Megalyridiini . The justification for redefining Megalyrinae is given in the Discussion.
