備考 Remarks

*Ishii, N. and Sawada, T. (1938a [4]) 以降 Dactylogyrus inversus はマサバから得られておらず，この記録は宿主の誤同定または取り違えの可能性が指摘されている [9].

* Ishii, N. and Sawada, T. (1938a [4]) reported Dactylogyrus inversus from the chub mackerel Scomber japonicus, but there has been no rediscovery of D. inversus on this host. It is possible that that this record misidentified or confused the hosts [9].
