Description. FEMALE (4 paratypes). Body, including gnathosoma, 350 long (350–375), 187 wide (185– 200). Ventral projections of subcapitulum 35 long (33–36), slightly curved, situated ventro-laterally. Propodonotal shield length 60 (55–65), maximum width 80 (80–85). Posterior margin of propodonotal shield widely rounded. Setae se 8 long (8–9). Idiosoma dorsally finely and irregularly striated. Alveoli of setae ps3 present; alveoli of setae c3 situated at coxal apodemes III; setae 4b. Setae g and h3 represented by alveoli. Setae h2 60 long (60–70). Sternum about 50 long. Foramen between sternum and fusion of apodemes II absent. Lateral projections of sternal branches and posterior projections of coxal fields I absent. Posterior apodemes of coxal fields II short, about 25 long, with free distal ends. Apodemes of coxal fields III fused to each other medially and with epigynum. Inseminatory canal about 25 long. Distal ends of coxal apodemes IV fused with sclerotized areas of oviporus by narrow sclerotized bands. Setae g situated at these apodemes. Sclerotized areas between setae h2 and h3 absent. Trochanters III–IV ventrally with distinctly developed, tonguelike protrusions. Setae vF I–II about 25 long. Setae kT III situated in basal part of tibiae. Setae r I–II about 7 long, r III–IV about 5 long.

MALE (3 paratypes). Body, including gnathosoma, 330–340 long, 170–180 wide. Ventral projections of subcapitulum 30–33 long, slightly curved, situated ventro-laterally. Propodonotum as in female. Propodonotal shield length 55–58, maximum width 70–80. Setae se 6–7 long. Idiosoma dorsally finely and irregularly striated. Alveoli of setae c3, 4b, ps2, and microspines ps3 present. Alveoli c3 and 4b situated at coxal apodemes III–IV, respectively. Setae g and h3 represented by microspines. Setae h2 65–70 long. Sternum 50 long. Lateral projections of sternal branches and posterior projections of coxal fields I absent. Posterior apodemes of coxal fields II short, 30 long, with free distal ends. Foramen between sternum and fusion of apodemes II absent. Apodemes of coxal fields III fused to each other. Pregenital sclerite fused with apodemes of coxae IV. Apodemes IV bearing setae 4b. Aedeagus, excluding the most anterior part, crimped, about 85 long. Adanal shields fused to each other, bearing setae ps2. Trochanters III–IV each ventrally with distinctly developed, tongue-like protrusions. Setae kT III situated in basal part of tibiae.

TRITONYMPH. Idiosomal setae si absent, delayed to adult.

Type material examined. Female holotype, 6 female, 2 male, 2 tritonymph, and 2 larva paratypes ( HK 88-0713-001) from Pteropus leucopterus Temminck (Pteropodidae) ( USNM 573264 ) [nasal cavities], PHIL- IPPINES: Catanduanes Prov. , Catanduanes Isl., 8 km W, 1 km N Gigmoto, 13°48'N, 124°19'E, 200 m, 25 February 1988, coll. E.A. Rickart ( EAR 1698 ) ; 1 female, 1 male paratypes ( HK 88-0715-001) from same host ( USNM 573263 ) [nasal cavities], same locality, date and collector ( EAR 1697 ) .

Type deposition. Holotype is deposited in USNM, paratypes in NMP, OSAL, UMMZ.

Host ranges and distribution. This species is known only from the type host, Pteropus leucopterus from the Philippines.

Etymology. This species is named in honor of Dr. Hans Klompen (OSAL) in recognition of his contributions to this study and the study of acarine systematics in general.

Remarks. This species is closely related to O. asiaticus . In both species setae c3 are present, setae f2 are absent, and setae 4a are absent in the female and present in the male, setae ps3 and h3 are represented by alveoli, and apodemes III are fused to each other. O. klompeni sp. nov. differs from O. asiaticus by the following characters. In O. klompeni sp. nov., the posterior projections of coxal fields I are absent, in females setae ps3 are present. In O. asiaticus the posterior projections of coxal fields I are present, tongue-like, and distinctly developed, in females setae ps3 are absent.
