MALE. Not found. Type material. Female (HOM) holotype and paratypes: 2 females (HOM), 1 female (HET), 1 tritonymph, 1 larva (reg. no. AMU-SYR.901) from Zebra Dove Geopelia striata (Linnaeus) (Columbiformes: Columbidae), INDO-NESIA: Java, Trinil, coll. W. Elbert [host reg. no. ZSM 08.862]; 4 females (HOM) (reg. no. AMU-SYR.904) from same host species, INDONESIA: Java, 21 May 1909, coll. A. Primavesi [host reg. no. ZSM 10.1015]; 3 females (HOM) (reg. no. AMU-SYR.905) from same host species, INDONESIA: Sumatra, Martin, 1895, coll. unknown [host in the ZSM, uncatalogued]; 1 female (HET) (reg. no. AMU-SYR.906) from same host species, INDONESIA: Celebes, Makassar, coll. M. Weber [host reg. no. ZSM 09.4342]. Type material deposition. All type specimens are deposited in the AMU. Additional material. Columbiformes (Columbidae): 6 females (HOM) (reg. no. AMU-SYR.902) from Diamond Dove Geopelia cuneata (Latham), AUSTRALIA: no other data [host reg. no. ZSM 21.1951]. 5 females (HOM), 1 protonymph (reg. no. AMU-SYR.903) from Peaceful Dove Geopelia placida Gould, AUSTRALIA: Melbourne, 1890, coll. unknown [host in the ZSM, uncatalogued]. 8 females (HOM) (reg. no. AMU-SYR.907) from Creasted Pigeon Ocyphaps lophotes (Temminck), AUSTRALIA: Adelaide, coll. Beyer [host in the ZSM, uncatalogued]. Whole mite material is deposited in the AMU and ZSM. Differential diagnosis. Peristerophila geopelis sp. nov. is morphologically most similar to P. mucuya (Casto, 1980) described from Columbina passerina (Columbidae) from USA (Texas) (Casto 1980). In females of both species, the infracapitulum is punctate; lateral and medial branch of the peritremes has 5 and 2 chambers, respectively; and the hysteronotal shield is reduced to the single sclerite which is not fused with the pygidial shield. This new species differs from P. mucuya by the following features: in females of P. geopelis, the propodonotal shield is entire and T-shaped; bases of setae c1 are situated on the propodonotal shield. In females of P. mucuya, the propodonotal shield is divided onto three oval-shaped sclerites; bases of setae c1 are situated out of propodonotal shield. Etymology. The name geopelis is taken from the generic name of the host.
