Setae h1 and f1 subequal in length. Coxal fields I, III, and IV punctate, II apunctate. Bases of setae 3a situated out of coxal fields III. Setae 3c twice as long as 3b. Length ratio of setae ag1:ag2:ag3 1.7‒2.1:1:2.6‒2.7. Genital setae (g1–2) subequal in length and 3 times longer than pseudanal setae (ps1–2). Legs. Setae tc”III‒IV 1.8‒2.3 times longer than tc’III‒IV. Length ratio of legs I:II 1–1.2:1. Lengths of setae: ve 35 (40–45), si 165 (180), se 185 (185–205), c1 220 (185), c2 205 (185–205), d1 165 (140), d2 195 (175– 215), e2 150 (160–175), f1 30 (30–35), f2 150 (155–170), h1 30 (25–30), h2 310 (280–300), ag1 80 (85–95), ag2 45 (40–45), ag3 120 (110–120), g1 and g2 30 (30), ps1 and ps2 10 (10), tc’III–IV 20 (15–20), tc”III–IV 40 (35–45), 3b (30–35), 3c (70–85). Length of apodemes I 60 (60‒65). Length of legs I 60 (60‒75), legs II 55 (50‒70).

FEMALE, HETEROMORPHIC FORM and MALE. Not found.

Type material. Female (HOM) holotype, 2 female (HOM) paratypes (reg. no. AMU-SYR.900) from Whiteheaded pigeon Columba leucomela Temminck ( Columbiformes : Columbidae ), AUSTRALIA: no other data [host in ZSM uncatalogued].

Type material deposition. All type specimens are deposited in the AMU.

Differential diagnosis. Peristerophila leucomela sp. nov. is morphologically similar to P. claravis Glowska and Skoracki, 2008 described from Claravis pretiosa Ferrari-Pérez ( Columbidae ) from Bolivia (Glowska & Skoracki 2008). In females of both species, the infracapitulum is punctate, the propodonotal shield is divided onto three sclerites and the hysteronotal shield is absent. This new species differs from P. claravis by the following features: in females of P. leucomela , bases of setae ve and si are situated on the lateral propodonotal shields; the lengths of setae si, d1, and f2 are 165‒180, 140‒165, and 150‒170 respectively; and the pygidial shield is punctate. In females of P. claravis , bases of setae ve and si are situated off the lateral propodonotal shields, the lengths of setae si, d1, and f2 are 25‒35, 205‒255, and 230‒260 respectively; and the pygidial shield is apunctate.

Etymology. The name leucomela is taken from the specific name of the host.
