Type material. Female holotype, 4 female and 2 male paratypes (Reg. No. AMU-SYR.526) from lesser covert quill of Chalcophaps indica (Linnaeus) ( Columbiformes : Columbidae ), INDONESIA: West Timor, 4 July 1911, coll. C. B. Haniel.

Types deposition. All type material is deposited in the AMU, except 1 female paratype in the ZSM.

Differential diagnosis. Meitingsunes chalcophaps sp. nov. is morphologically similar to M. zenadourae ( Clark, 1964) described from Zenaida macroura (Columbidae) in the USA. In females of both species, each lateral branch has six chambers; all coxal fields are apunctate, and bases of setae 3a are situated off coxal fields III. This new species differs from M. zenadourae by the following features: in females of M. chalcophaps , the propodonotal shield is divided into two triangular sclerites, bases of setae ve, si, and se are situated off the propodonotal shield; the hysteronotal shield is reduced to a single, triangular sclerite, bearing bases of setae d1; the pygidial shield is punctate near bases of setae f2 and f1. In females of M. zenadourae, the propodonotal shield is entire and rectangular in shape, bearing bases of setae ve, si and se; the hysteronotal shield is divided into three sclerites—two lateral, oval sclerites surrounding bases of setae d2 and an unpaired rectangular sclerite situated between bases of setae d1; central part of the pygidial shield is punctate.

Etymology. The name " chalcophaps " is taken from the generic name of the host.
