• [Note: Zettel et al., 2016: 136, 141, suggest that Diacamma rugosum ceylonense moicum Forel, 1911f was made available by Santschi, 1932d: 14. But in Santschi’s text he merely mentions “la var. moicum”, which is interpreted here as an abbreviated writing of the full quadrinomial, not as a statement of change of taxonomic status.]
