  • clarki. Rhytidoponera (Chalcoponera) clarki Donisthorpe, 1943e: 115.
    • Replacement name for Chalcoponera hilli Clark, 1941: 85. [Junior secondary homonym of Rhytidoponera (Rhytidoponera) hilli Crawley, 1915a: 131.]
    • Junior synonym of obscurum: Brown, 1958g: 203, 286.
    • [Note: both clarki Donisthorpe, 1943, and hilli Clark, 1941, are junior synonyms of obscurum Forel, 1900b: 60 (itself a junior primary homonym of Ectatomma obscurum Emery, 1896g: 48) (synonymy by Brown, 1958g: 203); hence clarki Donisthorpe is first available replacement name for hilli Clark, 1941 (Brown, 1958g: 203, 286).]
    • Status as species: Brown, 1958g: 203, 286; Taylor & Brown, 1985: 41; Taylor, 1987a: 68; Bolton, 1995b: 378.
