Abstract: The genera of the subfamily Cenocoeliinae Szepligeti are revised, keyed and illustrated. The genera Capitonius Brulle, 1846, Aulacodes Cresson, 1865, Lestricus Reinhard, 1866, Promachus Cresson, 1887, and Evaniomorpha Szepligeti, 1901, are re-instated. One new genus is described and illustrated: Rattana (type species: Cenocoelius albopilosellus Cameron, 1901) from Sulawesi, Misool, and New Guinea. The genus Ussurohelcon Belokobylskij, 1989, is transferred from the Helconinae to the Cenocoeliinae and placed in the new tribe Ussurohelconini. The following new synonyms are given: Iseurini Hedqvist, 1959, with Cenocoeliini Szepligeti, 1901; Iseura Spinola, 1853, with Capitonius Brulle, 1846; Cenocoelius bicolor Szepligeti, 1900, with Rattana indidiator (Smith, 1863); Laccophrys magdalini Foerster, 1862, and Cenocoelius hungaricus Zilahi-Kiss, 1927, with C. analis (Nees, 1834); C. femorator Tobias, 1973, with Lestricus secalis (Linnaeus, 1758). New combinations are: Bracon medenbachii (Snellen van Vollenhoven, 1878); Capitonius tricolor (Enderlein, 1920), C. andirae (Saffer, 1977); Promachus longius (Chou & Lee, 1991), P. taiwanensis (Chou & Lee, 1991), P. fortis (Saffer, 1982); Rattana albopilosella (Cameron, 1911), R. cephalotes (Smith, 1860), and R. insidiator (Smith, 1863).
TL;DR: The genus Atopandrium Graham, 1952 (Alysiinae: Alysiini) is synonymized with Aphaereta Foerster, 1862, Wachsmannia Szepligeti, (September) 1900, and Promachus Cresson, 1887 nec Loew, 1848 (Cenocoeliinae): Cenocoelius Haliday, 1840.
Abstract: The genus Atopandrium Graham, 1952 (Alysiinae: Alysiini) is synonymized with Aphaereta Foerster, 1862, Wachsmannia Szepligeti, (September) 1900 (Doryctinae: Doryctini) with Hypodoryctes Kokujev, (August) 1900, and Promachus Cresson, 1887 nec Loew, 1848 (Cenocoeliinae) with Cenocoelius Haliday, 1840. Atopandrium loripenne Graham, 1952, and Trisynaldis conflucta Fischer, 1958, are synonymized with Aphaereta debilitata Morley, 1933. Aphaereta palea (Papp, 1990), Hypodoryctes spathiiformis (Ratzeburg, 1848), and Cenocoelius aartseni (van Achterberg, 1994) are new combinations. A lectotype is designated for Aphaereta debilitata Morley, 1933.
