Type material Female holotype , 10 female paratypes and 2 male paratypes (AMU–SYR.267) from body feathers of Terathopius ecaudatus (Daudin, 1800) ( Falconiformes : Accipitridae ); bird imported from Africa to ZOO, Poland , Wroclaw in 1 April 1914 . Host specimen deposited at MNHW. Mite material deposited at AMU, except two female paratypes at ZISP. Host specimen is deposited at MNHW. Etymology The name accipitridicus refers to the family name of the host. Differential diagnosis Peristerophila accipitridicus sp. nov. is morphologically similar to P. columba (Hirst, 1920) known from feral dove Columba livia ( Columbiformes : Columbidae ) ( Kethley 1970 ). Females of both species have the hypostomal apex ornamented by two pairs of small sausage-like median protuberances and two pairs of lips; the stylophore is rounded posteriorly; setae c1 are slightly longer than se and c2 ; the hysteronotal shield is not fused to the pygidial shield; the apodemes I are slightly divergent and fused to apodemes II. This new species differs from P. columba by the presence of the following characters: in females of Peristerophila accipitridicus sp. nov. , the length ratios of setae l1 : e and ve : si are 1:1 and 1:2–2.7, respectively, the length of setae 3c is 115–125; the propodonotal shield is divided into three sabrelike sclerits. In females of P. columba the length ratios of setae l1 : e and ve : si are 1:1.6 and 1:1.2–1.5, respectively, the length of setae 3c is 65; the propodonotal shield is entire.
