Ho et al. (2007) described C. dactylus as a new species based on material of both sexes collected from Dactyloptena peterseni (Nyström, 1887) landed in Taiwan. They made detailed comparisons between their new species and C. priacanthi Pillai, 1961, but did not compare it with C. dactylopteni Uma Devi & Shyamasundari, 1981 described from material taken from another species of flying gurnard, Dactyloptena orientalis (Cuvier, 1829), caught at Waltair on the coast of India (Uma Devi & Shyamasundari, 1981). The descriptions match in every respect and there are no significant differences between these two species. We therefore propose to treat C. dactylus Ho, Lin & Chang, 2007 as a junior subjective synonym of C. dactylopteni Uma Devi & Shyamasundari, 1981.
