New quill mites of the family Syringophilidae (Acari: Cheyletoidea).

Five new species and two new genera belonging to the family Syringophilidae (Acari: Cheyletoidea) are described from birds that died in the Antwerp Zoo during their quarantine: Charadriaulobia vanelli n. g., n. sp. from Vanellus chilensis (Charadriiformes: Charadriidae) in Brazil; Fritschisyringophilus lonchurae n. g., n. sp. from Lonchura punctulata (Passeriformes: Estrildidae) in India; Mironovia coturnae n. sp. from Coturnix coturnix (Galliformes: Phasianidae) in Europe; Syringophiloidus daberti n. sp. from Passerina ciris (Passeriformes: Emberizidae) in Mexico; and S. serini n. sp. from Serinus mozambicus (Passeriformes: Fringillidae) in Central Africa. Charadriaulobia n. g. differs from the closely related Aulobia Kethley, 1970, in both sexes, by the divergent epimeres I; in females, by the absence of protuberances on the hypostomal apex and by the situation of the bases of setae l4 distinctly anterior the bases of setae d4. Fritschisyringophilus n. g. differs from the closely related Syringophiloidus Kethley, 1972, in both sexes, by the presence of setae vs ' on legs II, the absence of setae dT on legs III and IV; in females, by the presence of median hypostomal protuberances and by short setae l1, l2 and l3. The relationships between the Syringophilidae and their hosts are briefly discussed. A list of all known syringophilid genera and their distribution on bird families is provided.
