Revision of the Scytinopteridae (Hemiptera: Cicadomorpha: Scytinopteroidea) of the Queensland Triassic Author Lambkin, Kevin J. text Zootaxa 2016 4117 4 580 590 journal article 38935 10.11646/zootaxa.4117.4.9 1c5066ca-e49e-4817-9d82-bcf8e51971d4 1175-5326 257444 D156A0CF-B5E4-4465-BCBC-CDA15F029005 Mesoscytina australis Tillyard, 1919 ( Figs 1–3 ) Mesoscytina australis Tillyard, 1919 : 871 –872, text fig. 5. Mesoscytina affinis Tillyard, 1919 : 872 , text fig. 6. Syn. nov. Triassoscarta subcostalis Tillyard, 1919 : 874–875, text fig. 8. Syn. nov. Material. Holotype tegmen GSQ 112a, holotype tegmen of Mesoscytina affinis GSQ 235 (labelled “Undoubtedly = M. australis B[enjamin]. D[unstan].”), holotype tegmen of Triassoscarta subcostalis GSQ 116a, all Denmark Hill. Three additional tegmina: Denmark Hill: “Tegmen G” GSQ 320a/b+; Esk: ACC: QM F58693 +,? F58694 +. Description. Tegmen 9.3–9.5 mm long, 3.5–3.6 mm wide ( holotype 9.5, 3.5), length/width 2.6–2.9; R gently curved basally, at point of curvature costal space wider than space between R and M; RA strongly inclined; no colour pattern detected. Notes. The holotype of M. affinis is the basal half of a tegmen identical in size and venation to that of the holotype of M. australis . The Esk tegmen, QM F58693 ( Fig. 3 ), although older and from a different formation, is referred to the species on its similar size and basic venation, although CuA is more deeply forked than in the holotype . It has dSc well preserved. The other Esk tegmen is the same size but poorly preserved. Its identity therefore remains doubtful.
