Each medial branch of peritremes with 3 chambers, each lateral branch with 6 ‒ 7 chambers. Idiosoma. Propodonotal shield weakly sclerotized, reduced to 2 medial triangular shields with indiscernible margins. Length ratio of setae ve: si: c1 1:2.4 ‒ 2.7:3.6 ‒ 4.5. Bases of setae se situated slightly posterior to level of setae c1. Hysteronotal shield small, triangular, bearing bases of setae d1. Hysteronotal setae d2, d1, and e2 subequal in length. Pygidial shield well sclerotized in posterior part, punctate between bases of setae f1 and f2, anterior margin indiscernible. Setae f2 6.5 ‒ 7.8 times longer than setae f1. Coxal fields I ‒ IV well sclerotized, apunctate. Bases of setae 3a situated out of coxal fields III. Setae 3c 1.2‒1.7 times longer than 3b. Genital plate absent. Length ratio of setae ag1: ag2: ag3 3.1:1:2.5 ‒ 3.4. Genital setae (g1–2) subequal in length and twice as long as pseudanal setae (ps1–2). Legs.

MALE. Total body length 465‒500 in 2 paratypes. Gnathosoma. Each medial branch of peritremes with 3–4 chambers, each lateral branch with 5–6 chambers. Stylophore 160 long. Idiosoma. Propodonotal shield weakly sclerotized, all margins indiscernible, punctate below bases of setae si. Bases of setae se situated distinctly anterior to level of setae c1. Length ratio of setae ve: si: c1 1:1:1.2‒1.5. Hysteronotal shield with indiscernible medial part, bearing bases of setae d1 and e2, punctate near bases of setae d1.

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.
