Peritremes M-shaped, borders between chambers poorly visible. Length of stylophore 105 (105). Idiosoma . Propodonotal shield divided into 3 sclerites, 2 narrow lateral bearing bases of setae si and se and central bearing bases of setae vi, ve, and c1. Lateral and upper part of central shield punctate. Setae vi bases situated anterior to level of ve. All dorsal setae slightly beaded. Length ratio of setae vi:ve:si 1:1.6-2.6:2.2-3.8. Bases of setae c1 slightly anterior to se.

MALE. Unknown.

Etymology. The specific epithet derives from the generic name of the host.

Type material. Female holotype and 5 female paratypes from quill of body feathers of black-headed paradiseflycatcher Terpsiphone rufiventer (Swainson) ( Passeriformes : Monarchidae ), GABON: Ogooue Maritime Province (Moukalaba-Doudou National Park, NW corner of N'dogo Lagoon), 14 April 2003, coll. B.K. Schmidt (mites removed by E. Glowska). USNM catalog number of the host: 631583.

Type deposition. Holotype female and 2 female paratypes are deposited in the USNM, 3 female paratypes in the AMU.

Differential diagnosis. This new species is similar to N. locustella Skoracki et al., 2004 described from the common grasshopper-warbler Locustella naevia (Boddaert) ( Passeriformes : Locustellidae ) from Poland. In females of these species both infracapitulum and coxal fields are apunctate; the propodonotal shield is divided into three punctate sclerites; the genital and pseudanal setae are represented by a single pair each, the genital plate is restricted to the two narrow sclerites bearing bases of setae ag2, g, h1, and h2. This new species is distinguishable from N. locustella by the absence of the hysteronotal shield, quadratic pygidial shield, setae f1 ca. 1.2 longer than h1, and by setae ag1–3 subequal in the length. In N. locustella , the hysteronotal shield is present, pygidial shield is semicircular, setae f1 are twice longer than h1, length ratio of setae ag1:ag2:ag3 is 2:1:2.
