Although most of the other syntypes correspond to the same species, one of them, Humbert 6416, appears to belong instead to  C. trichotomus. 1928-09-14 de Fort-Dauphin, de Bevilany, Humbert, Swingle Madagascar 250 Prov. 1 Toliara lectotype 1928-11-06 1928-11-07 1928-11-06 de Beampingaratra, de Bevava, de Bekoho, H.
