( Fig. 38 )

Description. FEMALE (holotype). Body, including gnathosoma, 290 long, 145 wide. Ventral projections of subcapitulum 45 long, slightly curved, situated laterally. Propodonotal shield length 50, maximum width 60. Posterior margin of propodonotal shield widely rounded. Setae se 7 long. 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 45 long. Sternum about 40 long. Foramen between sternum and fusion of apodemes II absent. Lateral projections of sternal branches absent. Posterior projections of coxal fields I weakly developed, widely rounded. Posterior apodemes of coxal fields II short, about 30 long, with free distal ends. Apodemes of coxal fields III fused to each other medially and with epigynum. Inseminatory canal 20 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 each ventrally with distinctly developed, tongue-like protrusions. Setae vF I–II about 20 long. Setae kT III situated in basal part of tibiae. Setae r I–II about 10 long, r III–IV about 7 long.

MALE and TRITONYMPH. Unknown.

Type material examined. Female holotype ( BMOC 83-1600 - 070 ) from Macroglossus minimus ( UMMZ 159750 ) [nasal cavities], PHILIPPINES: Negros Oriental, Sibulan Municip., Lake Balinsasayao , 3km N, 14km W Dumaguete, 835m, 09°21'11"N, 123°10'45"E, 7 November 1982, coll. P.D. Heideman ( PDH 1081 ) .

Type deposition. Holotype is deposited in UMMZ.

Host range and distribution. This species is known only from the type host Macroglossus minimus from the Philippines .

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.

Remarks. This species is closest to O. klompeni and differs by the following characters. In females of O. macroglossus sp. nov. the posterior lobes of coxal fields I are present and the ventral projections of the subcapitulum are situated laterally. In O. klompeni the posterior projections of coxal fields I are absent and the ventral projections of the subcapitulum are situated ventro-laterally.
