Fig. 7

Description. Body surface finely rugose, pronotum leaf-like with crest elevated, with median undu- lated protuberance backwards; antennal groove situated below lower margin of compound eyes; eyes globose with flattened dorsal base; intra-ocular width of vertex between eyes from above is wider than vertical width of one compound eye; median carina anteriorly undulated and subtriangular, posteriorly undulated and rounded; pronotum with parallel radiating veins of higher caliber and small veins with smaller caliber throughout pronotum; lateral lobes being directed downwards, close to the body; fore and middle femora undulated; dorsal margin of hind femur excavated on distal portion ( Fig. 7 ).

Comments. Phyllotettix rhombeus ( Fig. 7 ) was mentioned in the early studies as Cicada rhombea and Membracis rhombea ( Hemiptera, Auchenorrhyncha ) by Felton (1765), Linnaeus (1767) and Fabricius (1775), until Westwood (1837) allocated this taxon to a genus of Orthoptera ( Cigliano et al. 2018) . This species did not have a diagnosis and the author did not designate the holotype in the original description. However, following the ICZN’s recommendation, this specimen is the holotype fixed by monotypy.
