Type material. Female holotype, 5 female and 3 male paratypes ( BMOC 81–0728 – 2 ) ex quill of Chrysocolaptes lucidus (Scopoli) ( Piciformes : Picidae ); THE PHILIPPINES: Luzon Is., Cagayan Prov., Pinablanca Munic., between Bagio and Iland Rivers , 11 May 1981, coll. K.M. Mudar.

Type deposition. All material is deposited at UMMZ .

Etymology. The name chrysocolaptes refers to the generic name of the host.

Differential diagnosis. N. chrysocolaptes sp. nov. is most similar to a sole formerly known species N. scirpaceus ( Skoracki, 1999) described from Acrocephalus scirpaceus (Hermann) ( Passeriformes : Sylviidae ) from Poland ( Skoracki 1999) and differs by the following characters: in females of N. chrysocolaptes sp. nov., one pair of pseudanal setae is present, each longitudinal branch of the peritremes has 4–5 chambers, and the hysteronotal shield is absent. In females of N. scirpaceus , two pairs of pseudanal setae are present, each longitudinal branch of the peritremes has 7–8 chambers, and the hysteronotal shield is present.
