(Polymerus) russatus sp. nov. and P. (Pachycentrum) unciniger sp. nov. The specific name P. funestus Reuter, 1906 is transferred from the subgenus Poeciloscytus Fieber, 1858 to the nominative subgenus and synonymised with P.pekinensis Horváth, 1901. New combinations for seven African, Indian, and Australian species are proposed: Charagochilus aureus (Ballard, 1927) comb. nov., Ch. bimaculatus (Poppius, 1910) comb. nov., Ch. consanguineus (Distant, 1904) comb. nov., Ch. flavipes (Distant, 1904) comb. nov., Ch. madagascariensis (Poppius, 1914) comb. nov., Ch. obscuratus(Poppius, 1914) comb. nov., Proboscidocoris solitus (Walker, 1873) comb. nov. The species Polymerus nitidus (Odhiambo, 1959) is returned to the genus Proboscidocoris. Five African and Arabian species are included in the new genus Dichelocentrum gen. nov.: D. alkadanum (Linnavuori & van Harten, 2005) comb. nov., D. flora (Linnavuori & van Harten, 2005) comb. nov., D. longirostre (Reuter, 1905) comb. nov., D. ornatifrons (Odhiambo, 1959) comb. nov. and D. transvaalicum sp. nov. The specific name Polymerus xerophilus Linnavuori, 1975 syn. nov. is synonymised with D. ornatifronscomb. nov. Key, diagnoses, data on distribution, and illustrations of the parameres, entirely inflated vesica and the gynatrium are provided for all recognised species from the subgenera Polymerus, Pachycentrum subgen. nov. and the genusDichelocentrum gen. nov
