also the unplaced fossil genus †Dinidorites Cockerell, 1921) in the two subfamilies: Dinidorinae The Dinidorinae Stål, 1868 includes the Dinidorini, which comprises tens of species, some with four-segmented and some with five-segmented antennae. tribe Amberianini J.A. Lis & Kocorek, 2014 Amberiana Distant, 1911 tribe Dinidorini Stål, 1868 Colpoproctus Stål, 1870 Colporidius Lis, 1990 Coridiellus Lis, 1990 Coridius Illiger, 1807 Cyclopelta Amyot & Serville, 1843 Dinidor Latreille, 1829 Patanocnema Karsch, 1892 Sagriva Spinola, 1850 tribe Thalmini Nuamah, 1982 The tribe Thalmini contains three species, each in its own genus. All three species have two-segmented tarsi. Folengus Distant, 1914 Thalma Walker, 1868 Urusa Walker, 1868 Megymeninae In the subfamily Megymeninae Amyot & Serville, 1843 the lateral margins of the abdomen and commonly also of the head and pronotum are produced into lobes, tubercles, or spines. In many species the pronotum bears a dorsal anteromedian tuberosity, or a posterior transverse ridge. In most species the legs are heavily and strongly spined; in others the antennae and legs are setulose. tribe Byrsodepsini Kocorek & Lis, 2000 Byrsodepsus Stål, 1872 tribe Eumenotini Bergroth, 1907 Afromenotes Kment & Kocorek, 2014 Eumenotes Westwood, 1847 tribe Megymenini Amyot & Serville, 1843 Doesbergiana Durai, 1987 - monotypic D. borneoensis Durai, 1987 Megymenum Guérin-Méneville, 1831 - 23 described species: several species with expanded pronotal margins and some have reduced hemelytra and are flightless. In most species the second valvifers are reduced, lightly sclerotized, and fused mesally. Work continues in establishing the taxonomy of the family in the light of molecular genetics. Current evidence suggests that Dinidoridae is in fact monophyletic and is a sister group to the Tessaratomidae. However the monogeneric tribe Eumenotini, including only the monotypic genus Eumenotes Westwood, had been seen as belonging in the Megymeninae. This however no longer seems defensible. The tribe actually looks closer to the Dinidorinae, but whether it should be assigned to Dinidorinae or to its own subfamily needs separate consideration. Biology All Dinidoridae appear subsist strictly on the sap of host plants in various families, more than twenty in number. Known hosts include members of the following families, on some of which some of the species are recognised as pests: Amaranthaceae Arecaceae Asclepiadaceae Asteraceae Balsaminaceae Convolvulaceae Cucurbitaceae Euphorbiaceae Fabaceae Malvaceae Moraceae Passifloraceae Pedaliaceae Poaceae Rubiaceae Rutaceae Sapindaceae Solanaceae Theaceae Urticaceae Distribution Dinidoridae occur mainly in far-eastern and African regions, but the genus Dinidor occurs in neotropical regions and species of Megymenum extend
