North American host records:
Rallidae:
Fulica americana, American Coot (Strandtmann 1948; Pence 1972, 1975; Knee et al. 2008)
Rallus elegans, King Rail (Strandtmann 1948; Pence 1975)

Diagnostic characteristics:
– podosomal shield largely complete, without extensive fragmentation

Note:
– Only Rallinyssus caudistigmus has so far been found in Canada. Two other species,
R. sorae
 Pence and Young, 1979,and R. verheyeni Fain, 1963 have beenrecorded from North
American birds. Rallinyssus verheyeni and R. sorae differ from R. caudistigmus by having an
extensively fragmentedpodosomal shield, as well as different chaetotaxy.
