( Figs. 3 G, 4)

Description. FEMALE, holotype. Total body length 560 (485–580 in 7 paratypes). Gnathosoma . Infracapitulum apunctate. Each medial branch of peritremes with 2–3 chambers, each lateral branch with 5–6 chambers. Length of stylophore 170 (170). Idiosoma . Propodonotal shield weakly sclerotized, divided into unpaired medial shield bearing bases of setae c1 and 2 lateral sclerites bearing bases of setae ve and si. Length ratios of setae ve: si: c1 and d2: d1: e2 1:2.4 ‒ 3.1:4.5 ‒ 5.4 and 1.2–1.3:1:1, respectively. Hysteronotal shield absent. Pygidial shield well sclerotized, punctate, with deeply concave anterior margin. Setae f2 8.4 ‒ 9.6 times longer than setae f1. Coxal fields I ‒ IV well sclerotized, sparsely punctate. Bases of setae 3a situated off coxal fields III. Setae 3c 1.4–2 times longer than 3b. Genital plate absent. Length ratio of setae ag1: ag2: ag3 2.3 ‒ 2.5:1:3 ‒ 3.4. Genital setae g1–2 subequal in length. Pseudanal setae ps1–2 subequal in length. Legs. Setae l'RII‒l'RIV subequal in length. Podomeres of legs III ‒ IV punctate. Setae tc"III‒IV 1.3 ‒ 1.5 times longer than tc'III‒IV. Fan-like setae p' and p" multiserrate, each with about 20 tines. Lengths of setae: ve 50 (50–55), si 130 (115–130), se 200 (200–225), c1 200 (195–225), c2 220 (220–240), d1 175 (170–195), d2 170 (150–210), e2 180 (165–180), f1 30 (25–30), f2 200 (190–225), h1 25 (25–30), h2 320 (290–320), ag1 105 (90–105), ag2 40 (40), ag3 150 (150–195), g1 and g2 20 (20–25), ps1 and ps2 15 (15) tc'III– IV 35 (30–40), tc" III–IV 55 (35–55), l'RII 30 (25‒30), l'RIII 40 (30‒40), l'RIV 40 (35–40), 3b 40 (30–45), 3c 90 (90–95).

MALE. Unknown.

Type material. Female holotype and 7 female paratypes (Reg. No. AMU-SYR.524) from lesser covert quill of Turacoena manadensis (Quoy and Gaimard) ( Columbiformes : Columbidae ), INDONESIA: Sulawesi Isl., Manado, coll. Frank.

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

Additional material. Four females (Reg. No. AMU-SYR.525) from lesser covert quill of Turacoena modesta (Temminck) (Columbidae) , INDONESIA: West Timor, 5 July 1911, coll. C. B. Haniel. All specimens deposited in the AMU, except 1 female in the ZSM.

Differential diagnosis. Meitingsunes turacoenas sp. nov. is morphologically similar to M. columbicus Skoracki, 2011 described from Columba oenas ( Columbiformes : Columbidae ) from Kazakhstan ( Skoracki 2011). In females of both species, the peritremes have the same number of chambers in each of medial (three chambers) and lateral (4–5) branches. This new species differs from M. columbicus by the following features: in females of M. turacoenas , bases of setae 3a are situated off coxal fields III; the hysteronotal shield is absent; the pygidial shield is sparsely punctate and with deeply concave anterior margin. In females of M. columbicus, bases of setae 3a are situated on coxal fields III; the hysteronotal shield is represented by a long narrow shield that is fused with the apunctate pygidial shield.

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