Remarks. Grallobia gallinulae was originally described by Gaud, 1968 based on the specimens collected from Gallinula chloropus in Rwanda.

While Grallobia gallinulae is very similar to Grallobia fulicae with regard to external traits, it can be clearly distinguished from Grallobia fulicae by the following characteristics: (1) prodorsal and hysteronotal shield strongly sclerotized on prodorsum and hysterosoma, respectively; (2) net-like pattern of hysteronotal shield absent; (3) posterior border of opisthosomal lobe with small tubercle in female ( Gaud, 1968). The morphology of the Korean specimens were consistent with that those of the original descriptions and illustrations by Gaud (1968).

Host. Specimens were collected from the surface of primary feathers on the wings of the common moorhen, Gallinula chloropus .

World distribution. Cameroun, Congo, Rwanda ( Gaud, 1968), Korea (This study).

Deposition. NIBRIV000000812252 and NIBRIV000000 812354-812356.

Molecular data. The COI sequences were obtained from two individuals and deposited in GenBank with accession numbers of MG545264 and MG545265.

Identifiers. Yeong-Deok Han and Gi-Sik Min.
