( Figures 6–19 )

Description

Female (holotype). Total body length 750 (650–750 in seven paratypes). Hypostomal apex ornamented by two pairs of large sausage-like median protuberances and two pairs of hypostomal lips. Cheliceral moveable digit, 120 (110–120) long. Each transverse branch of peritremes with two to three chambers, each longitudinal branch with three to four chambers. Stylophore rounded posteriorly, not punctated, 155 (145–155) long. Idiosoma. Propodonotal shield divided into three punctated, sabre-like sclerits. Length ratio of setae ve: si 1:2–2.8. Setae c1 slightly longer (1.1–1.3 times) than se and c2. Hysteronotal shield not fused to pygidial shield, not punctated, bearing bases of setae d1. Pygidial shield punctated posteriorly. Setae f1 and h1 short (4.5 and more times shorter than f2 and h2). Aggenital setae ag1 about 2.5 times longer than ag2. Genital setae g1 and g2 subequal in length, both 1.5–2 times longer than pseudanal setae ps1 and ps2. Legs. All coxal fields punctated. Setae tc”III–IV 2–3 times longer than tc ¢ III–IV. Setae 3c 3–4 times longer than 3b. Podomers of all legs punctated. Setae sc1, sc3 and sc4 extending respective genu, sc2 rich anterior margin of tibiae.

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.
