Type material examined. Female holotype, 4 female and 2 male paratypes ( BMOC 83-1600-064) from Haplonycteris fischeri Lawrence (Pteropodidae) ( UMMZ 159890), PHILIPPINES: Negros Oriental, Sibulan Municip., Lake Balinsasayao, 3km N, 14km W Dumaguete, 835m., 09°21'11"N, 123°10'45"E, 5 November 1982, P. Heideman ( PDH 1053); 2 female and 1 female tritonymph paratypes ( BMOC 83-1600-024) from same host ( UMMZ 159855) and locality, 27 August 1982, coll. P. Heideman ( PDH 771); 3 female and 1 larva paratypes ( BMOC 83-1600-007), same host ( UMMZ 159833) and locality, 2 July 1982, coll. P. Heideman ( PDH 493).

Non-type material examined. One male, 1 male tritonymph ( BMOC 83-1600-066) from Cynopterus brachyotis (Müller) (Pteropodidae) ( UMMZ 159666), PHILIPPINES: Negros Oriental, Sibulan Municip., Lake Balinsasayao, 3km N, 14km W Dumaguete, 835m, 09°21'11"N, 123°10'45"E, 12 November 1982, P. Heideman ( PDH 1066); 1 tritonymph (pharate female) ( HK 87-0727-001) from same host ( USNM 459028), PHILIPPINES: Leyte Prov., Maripipi Island, 1.8 km N, 3 km W Maripipi, 11°47'N, 124°19'E, 740m., 16 April 1987, coll. P.D. Heideman ( PDH 3314).

Type deposition. Holotype and paratypes in UMMZ, other paratypes in NMP, ZISP.

Host range and distribution. This species parasitizes Haplonycteris fischeri and Cynopterus brachyotis in the Philippines.

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

Remarks. This new species differs from M. polli by the presence of solenidia ϕ and setae kT on legs IV; in females of M. haplonycteris sp. nov. the body length, including the gnathosoma, is 270–285 long. In M. polli legs IV lack solenidia ϕ and setae kT, and the idiosoma is 305–325 long.
