Description.

Female (holotype).

Idiosoma, including gnathosoma, 525 long (500-550 in 3 paratypes), 360 wide (350-360) (Fig. 2). Gnathosoma 130 long (130-145), 130 wide (130-140). Palps 50-60 long, moderately inflated dorsally. All palpalae distinctly pectinate (Fig. 3A). Lengths of palpalae: dF 35 (35-35), dG 20 (20-25), and l"G 50 (40-50); dG slightly thicker and about 2 times shorter than dF and l"G. Setae vF 100-110 long, smooth. Subcapitulum ventrally with setae n and m, about 40 and 50 long, respectively. Peritremal branch about 85 long. Idiosoma 425 long (420-440). Anterior region of propodonotum covered by short irregularly situated folds, without scales or tubercles (Fig. 6A). Dorsal shield entire, 165 long in midline (160-170), 300 at maximum width (300-330) (Fig. 2A). Anterior and posterior margins of dorsal shield widely concave. Ventral surface of idiosoma with indistinct transverse striations, without scales or verrucosities (Fig. 2B). Setal lengths: vi, ve, and si - all distinctly barbed, subequal in length, 150-160; se, c2, and 1a - all smooth, 10-12; h1 whip-like, 250 (230-260); 1b smooth, about 40; 3a present, about 20. Base of legs I with distinctly developed and slightly attenuated fleshy lobe; base of legs II with moderately developed rounded lobe. Leg I with 2 articulated segments (Fig. 3B). Leg II with 2 articulated segments (Fig. 3C). Legs III, IV with one segment, each bearing 4 (more rarely 5) long setae. One ventral seta of leg III and 2 ventral seta of leg IV 100-120 long, about half the length of other setae situated dorsally or dorsoterminally, 200-250 long.

Male.

Unknown.

Etymology.

The species name is derived from the generic name of the host and is a noun in apposition.

Differential diagnosis.

This species belongs to the “plumaris” species group including three species, Neharpyrhynchus plumaris (Fritsch), Neharpyrhynchus novoplumaris (Moss et al.), and Neharpyrhynchus spinus Martinu et al. ( Martinu et al. 2008). In females of this group, legs I and II consist of the two articulated segments, palpal setae vF are smooth, the anterior region of the propodonotum is covered by short irregular striations, and setae 3a are present. Within this group, it is close to Neharpyrhynchus novoplumaris described from Certhia familiaris Linnaeus ( Passeriformes , Certhiidae ) [type host] and Cardinalis cardinalis (Linnaeus) ( Passeriformes , Cardinalidae ) from USA ( Moss et al. 1968). In females of both of these species setae dG are about half the lenth of l"G. In the other two species of the genus, setae dG and l"G are subequal. Females of Neharpyrhynchus chlorospingus differ from Neharpyrhynchus novoplumaris by the following characters. In Neharpyrhynchus chlorospingus , palpal setae dF are slightly shorter than l"G, setae se and c2 are about four times shorter than 1b, the posterior margin of the dorsal shield is widely concave. In Neharpyrhynchus novoplumaris , palpal setae dF are slightly longer than l"G, setae se and c2 are subequal or only slightly shorter than 1b, the posterior margin of the dorsal shield is widely convex.
