Redescription. FEMALE (paratype). Body, including gnathosoma, 290 long, 130 wide. Ventral projections of subcapitulum 30 long, slightly curved. Propodonotal shield length 55, maximum width 65. Setae se 23 long. Idiosomal dorsum covered by interrupted, wave-like striations. Setal lengths: c3, 4b, g, and 4a– about 3, ps3 5, h3 11. Setae h2 200 long. Sternum 35 long. Lateral projections of sternal branches absent. Posterior projections of coxal fields I weakly developed, widely rounded, 4 long, 7 wide. Posterior apodemes of coxal fields II short, about 10 long, with free distal ends. Apodemes of coxal fields III consisting of 2 parts, their distal parts fused to each other medially and with epigynum. Epigynum completely fused with apodemes III. Inseminatory canal about 25 long. Coxal apodemes IV bifurcated distally; their anterior branches fused with apodemes III; their posterior branches fused with sclerotized areas of oviporus by narrow sclerotized bands. Setae g situated off apodemal branches IV. Pair of sclerotized areas bearing setae h3 present. Setae vF I–II about 30 long. Trochanters III–IV with short widely rounded protrusions ventrally.

MALE (paratype). Body, including gnathosoma, 265 long, 140 wide. Ventral projections of subcapitulum 22 long, slightly curved. Propodonotal shield length 50, maximum width 55. Setae se 22 long. Idiosoma covered dorsally with wave-like pattern. All setae excluding ps2 present. Setae c3, 4b, g, 4a, ps3 about 3 long, h3 8 long. Setae h2 175 long. Sternum 40 long. Lateral projections of sternal branches absent. Posterior projections of coxal fields I widely rounded, about 3 long, 13 wide. Posterior apodemes of coxal fields II short, about 5 long, with free distal ends. Distal ends of apodemes III separated from each other medially. Pregenital sclerite 10 long, 8 wide. Setae 4b situated off coxal apodemes IV. Aedeagus about 35 long, smooth. Apodemes IV anteriorly curved but not completely fused with apodemes II. Adanal shields present, separate, bearing setae h3 and ps3. Setae vF I–II about 25 long. Trochanters III–IV with short widely rounded protrusions ventrally.

TRITONYMPH. Setae f2 delayed to adult.

Type material examined.. Two female, 1 male, 1 tritonymph, and 1 larva paratypes ( IRSNB) from Rhinolophus hipposideros (Bechstein) (Rhinolophidae) , BELGIUM: Wallonia Reg., Liege Prov., Huccorgne , 50°34'N, 05°10'E, 17 February 1959, coll. A. Fain.

Type deposition. Holotype is deposited in IRSNB.

Host range and distribution. This species was originally collected from Rhinolophus hipposideros (type host) from Belgium and initially determined as O. zumpti ( Fain 1959a) . Later, Fain (1967) described O. striatus based on these specimens and also recorded the species from Rhinolophus deckenii Peters from Tanzania and Asellia tridens (Geoffroy) (Hipposideridae) from Libya. The records of O. zumpti from Rhinolophus ferrumequinum from Belgium ( Fain 1959a) and Ukraine ( Zabludovskaya 2005) could possibly refer to P. striatus . We examined only specimens from the type host; other records should be reconfirmed.
