Caligus dactylus Ho, Lin & Chang, 2007

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 .
