Propodonotal shield entire, rectangular in shape, punctate, bearing bases of setae vi, ve, si, se and c1. Length ratio of setae vi: ve: si 1:3.5–4.3:3.8–4. Hysteronotal shield entire, apunctate, bearing bases setae e2 and d1. Setae d2 8 times longer than e2. Pygidial shield apunctate. Agenital plate apunctate, well sclerotised, its anterior margin reach setae 4b. Setae ag1 slightly (1.2 times) longer than ag2. Setae 3c about 3 times longer than 3b.

Type material. Female holotype, 8 female and 3 male paratypes from quill of body feathers of Ptilinopus iozonus Gray (Columbidae); PAPUA NEW GUINEA: April 1910, coll. Wiedenfeld.
Type material deposition. All specimens are deposited in the AMU (Reg. No. AMU-SYR.489), except 1 female paratype in the ZSM (Reg. No. ZSM- 20112043) and 1 female paratype in the ZISP (ZISP-AVB 011-2908- 023).
Additional material. Four females from Ducula pistrinaria Bonaparte (Columbidae), PAPUA NEW GUINEA: New Britain Island, 17 August 1912, coll. Basenbruch (deposited in the AMU (Reg. No. AMU-SYR.496) and 1 female in the ZSM (Reg. No. ZSM- 20112044)). Two females and 3 males from Ducula rosacea (Temminick) (Columbidae); INDONESIA: East Nusa Tenggara, Kupang, Semau Island, 21 April 1911, coll. Haniel (deposited in the AMU (Reg. No. AMU-SYR.497), except 1 female in the ZSM (Reg. No. ZSM 20112051)). Three females from Ducula rufigaster (Quoy and Gaimard) (Columbidae), PAPUA NEW GUINEA: Astrolabe, 5 March 1894, coll. Hagen (deposited in AMU (Reg. No. AMU-SYR.498)). One female from Ducula luctuosa (Temminick) (Columbidae), INDONESIA: Sulawesi Island, coll. Rvedel (deposited in AMU (Reg. No. AMU-SYR.501)). Two females from Ducula spilorrhoa (Gray) (Columbidae), PAPUA NEW GUINEA: 17 March 1911, coll. Wiedenfeld (deposited in AMU (Reg. No. AMU-SYR.502)).
Differential diagnosis. This new species is distinguished from a single previously described species in this genus, Gunabopicobia zumpti (Lawrence, 1959), by the following features: in females of G. masalaje sp. nov., each medial branch of the peritremes has 6–7 chambers, each lateral branch has 5–6 chambers; the propodonotal shield is densely punctate near bases of setae vi and si; the length ratios of setae vi: ve: si and ag1: ag2: ag3 are 1:2.5–2.7:2.6–2.8 and 2.8–3.5:1:3.8–4, respectively. In females of G. z u m p t i, each medial branch of the peritremes has 2–3 chambers, each lateral branch of the peritremes has 10–11 chambers, the length ratios of setae vi: ve: si and ag1: ag2: ag3 are 1:2–2.2:3.2–3.8 and 1:1:3, respectively.
Etymology. The specific epithet “ masalaje ” derives from the Papuan and New Guinean spirit which inhabit the forest—Masalaje.
