I have removed Crematogaster (Cr.) clepens (Cremastogaster opaciceps Mayr v. clepens n. v., Forel, 1913h: 353, worker) from Zaïre, at Congo da Lemba, by R. Mayné, to separate species status. Similarly I have removed the acacia inhabiter Crematogaster (Cr.) defleta (Cremastogaster opaciceps Mayr subsp. defleta n. subsp., Forel, 1910e: 434, worker) from South Africa, in Acacia horrida - see below

Mayr's (1901b) description is at {original description}. Forel's (1914d) description of cacodaemon is at {original description}. Arnold (1920a) gave a translation of the type plus that of defleta, this is at {original description}. Arnold (1920a) also gave a translation of cacodaemon, this is at {original description}.
The report of defleta as in an acacia suggests a distinct species to the carton nesting type form. The type workers also quite strongly indicate that both defleta and clepens are distinct species. The first is smaller, differently coloured, has notably shorter propodeal spines and short scapes. The second is darker, smaller and has a more rounded head.
