A monograph of Afrotropical and Mediterranean Derelomus Schoenherr, 1825 (Coleoptera: Curculionidae) with the descriptions of 14 new species

The species of the genus Derelomus Schoenherr, 1825 (Curculionidae: Curculioninae: Derelomini) from the Afrotropical (excluding Madagascar) and Mediterranean regions are here revised. In total, 32 valid species are recognized, including 14 described as new: D. acuminatus Haran sp. nov.; D. baka Haran sp. nov.; D. brevis Haran sp. nov.; D. brunneus Haran sp. nov.; D. caldarai Haran sp. nov.; D. crypticus Haran sp. nov.; D. discus Haran sp. nov.; D. karooensis Haran sp. nov.; D. peglerae Haran sp. nov.; D. prochesi Haran sp. nov.; D. setifer Haran sp. nov.; D. strangulatus Haran sp. nov.; D. strelitziae Haran sp. nov. and D. trinotatus Haran sp. nov. The following new synonymies are proposed: D. pallidus Hartmann, 1904 and D. hartmanni Klima, 1934 = D. pallidus Fåhraeus, 1844 syn. nov.; D. rectirostris Hustache, 1937 = D. languidus Fåhraeus, 1844 syn. nov.; D. subcostatus Boheman, 1844 = D. chamaeropis (Fabricius, 1798) syn. nov.; D. kocheri Hoffmann, 1957 = D. piriformis (Hoffamnn, 1938) syn. nov.; D. auberti Hustache, 1932 = D. ephippiger Gyllenhal, 1836 syn. nov and Psilocaulus elatus Richard, 1958 = Derelomus costiger Marshall, 1958 syn. nov. Morphological examination of specimens and molecular analyses enabled recognising four main species groups: the D. signatus Gyllenhal, 1836 group (eight species) associated with the inflorescences of species of Vachellia Wight & Arn. (Fabaceae), the D. pallidus Fåhraeus, 1844 group (three species) associated with Achariaceae and Ebenaceae, the D. nigrovariegatus Hustache, 1936 group (six species) associated with Strelitzia (Strelitziaceae) and Phoenix reclinata Jacq. (Arecaceae) and the D. ephippiger Gyllenhal, 1836 group (12 species) associated with male inflorescences of various palms (Chamaerops L., Cocos L., Phoenix L.; Arecaceae). A key and a description or redescription are provided for each species, with illustrations of habitus of adults and male terminalia.

The species of the genus Derelomus Schoenherr, 1825 (Curculionidae: Curculioninae: Derelomini) from the Afrotropical (excluding Madagascar) and Mediterranean regions are here revised. In total, 32 valid species are recognized, including 14 described as new: D. acuminatus Haran sp. nov.; D. baka Haran sp. nov.; D. brevis Haran sp. nov.; D. brunneus Haran sp. nov.; D. caldarai Haran sp. nov.; D. crypticus Haran sp. nov.; D. discus Haran sp. nov.; D. karooensis Haran sp. nov.; D. peglerae Haran sp. nov.; D. prochesi Haran sp. nov.; D. setifer Haran sp. nov.; D. strangulatus Haran sp. nov.; D. strelitziae Haran sp. nov. and D. trinotatus Haran sp. nov. The following new synonymies are proposed: D. pallidus Hartmann, 1904 and D. hartmanni Klima, 1934 = D. pallidus Fåhraeus, 1844 syn. nov.; D. rectirostris Hustache, 1937 = D. languidus Fåhraeus, 1844 syn. nov.; D. subcostatus Boheman, 1844 = D. chamaeropis (Fabricius, 1798) syn. nov.; D. kocheri Hoffmann, 1957 = D. piriformis (Hoffamnn, 1938) syn. nov.; D. auberti Hustache, 1932 = D. ephippiger Gyllenhal, 1836 syn. nov and Psilocaulus elatus Richard, 1958 = Derelomus costiger Marshall, 1958 syn. nov.
