Diagnosis. Body oblong to oval, total length 6–10, frequently uniformly green, brown or black dorsally (Fig. 3); sulcus of vertex very narrow, sometimes absent; basal carina of vertex indistinct; eyes wide, posterior margin contiguous with pronotal collar; first antennal segment stout, slightly club-like, with some stiff, erect setae, other segments thinner, second also often club-like; labium reaching posterior coxae; pronotal collar pilose, stiff setae on anterior corner of pronotum present; scutellum flat to slightly swollen, not ampulla-like; legs elongate, tibial spines dark, brown to blackish; hemelytral punctation double, one type very reduced but dense and shallow, the second, shallow but larger, hemelytral pilosity simple; primary apophysis of left paramere with two rounded accessory lobes; secondary gonopore reduced, devoid of a sclerite, with a thin rim; phallic comb always present, with two lateral ranks of tooth; phallic true spiculum frequently elongate and pointed; phallic support absent; parieto-vaginal rings large, devoid of anterior projection; dorso-labiate plate reduced; dorsal process, median process and interramal lobes of posterior wall developed. Included species. Based on the published data (external anatomy, male genitalic structures) and our personal observations, the following species are members of the genus Adelphocoris: A. albonotatus (Jakovlev, 1881), A. bimaculicollis Lindberg, 1948, A. corallinus Kerzhner, 1988, A. demissus Horváth, 1905, A. detritus (Fieber, 1861), A. fasciaticollis Reuter, 1906, A. fasciiger Reuter, 1906, A. ferrugineus Hsiao, 1962 *, A. flavovirens Yasunaga, 1996, A. funestus Reuter, 1903, A. fuscicornis Reuter, 1903 *, A. hercynicus Wagner, 1938, A. insignis Horvath, 1898, A. josifovi Wagner, 1968, A. laevisculus Vinokurov, 1976, A. lineolatus (Goeze, 1778) *, A. luridus Reuter, 1906, A. melanocephalus Reuter, 1903, A. minor Wagner, 1969, A. nigritylus Hsiao, 1962 *, A. obliquefasciatus Lindberg, 1934, A. piceosetosus Kulik, 1965, A. ponghvariensis Josifov, 1978, A. quadripunctatus (Fabricius, 1794) *, A. rapidus (Say, 1832) *, A. reichelii (Fieber, 1837) *, A. rufescens Hsiao, 1962 *, A. seticornis (Fabricius, 1775) *, A. sichuanus Kerzhner & Schuh, 1995, A. suturalis (Jakovlev, 1882), A. taeniophorus Reuter, 1906, A. tenebrosus (Reuter, 1875), A. tibetanus Zheng & Li, 1990, A. ticinensis (Meyer-Dür, 1843) *, A. triannulatus (Stål, 1858), A. vandalicus (Rossi, 1790) *, A. variabilis (Uhler, 1897), A. vinokurovi Yasunaga, 1996, A. zoui Zheng & Li, 1990. Distribution. Holarctic genus, including two species known from the New World (A. rapidus and the introduced A. lineolatus). Host plants. Mainly collected on Fabaceae and Asteraceae, some species recorded from Apiaceae, Curcubitaceae, Lamiaceae, Liliaceae, Tamaricaceae and Urticaceae (Schuh 2002-2013). Discussion. Some species such as A. divergens Reuter, 1906, A. medialis Zheng, 2004 or A. torquatus Reuter, 1906 are probably also members of the genus Adelphocoris, but a study of male genitalic structures would be necessary to confirm the generic placement.
