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.
