Type material. Holotype female ( OSAL 0083369), 2 female and 1 male paratypes ( OSAL 0 0 82614, 0 0 83352, 0083388) from Xanthocephalus xanthocephalus (Bonaparte) ( Passeriformes : Icteridae ), USA: Nebraska: Cherry Co., Valentine, 24.1 km S of, 42.87°N, 100.55°W (USGS-GNIS), 4 September 1960, coll. N. Braash & W.T. Atyeo.

Type deposition. OSAL.

Hosts and distribution. This species is known only from the type host Xanthocephalus xanthocephalus (Icteridae) from North America (present paper; see Table 1 ). Moss (1979) misidentified this species as H. brevis .

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

Differential diagnosis. The new species is very close to H. zumpti and H. vulgaris . In these species, the leg setation is the same and palpalae l”G are maximum 1.5 longer than palpalae dF. Females of this new species differ from those of H. zumpti mainly by longer setae h2 100–135 long (vs. 50–80 long in H. zumpti ) and less so by the body length, including gnathosoma, 320–340 long (vs. 340–420 long in H. zumpti from most hosts). Females of H. zumpti from Passer domesticus in Algeria, however, have a short body—about 330 long. Females of H. xanthocephalus differ from H. vulgaris by the shorter body (370–400 long in H. vulgaris ) and by palpalae l”G being 1.4 times longer than dF in H. xanthocephalus and maximum 1.3 longer in H. vulgaris . This new species, however, clearly differs from both of the above mentioned species by the male features. In males of H. xanthocephalus , genital setae g1 are about 20 long and setae vi are about 100 long, whereas in males of H. zumpti and H. vulgaris , setae g1 are 9–11 long and setae vi are 35–50 long.

Harpyrhynchoides spizella sp. nov. ( Fig. 8 )

Harpyrhynchus brevis, Moss 1979: 381 (misidentification)

Diagnosis. FEMALE. Palp femoragenu with distinct lateral notches. Palpalae l”G 1.3 times longer than dF. Body, including gnathosoma, 280–325 long. Setae h2 40–50 long. Vulva with long lateral folds reaching posterior margin of idiosoma. Genua I and II with 3 setae (v ” absent). Apical segment of legs III with 5 setae, apical segment of legs IV with 4 setae.

Description. FEMALE (holotype, Fig. 7 ). Body, including gnathosoma, 280 long (280–325 in 10 paratypes) and 240 wide (240–250). Gnathosoma 70 long (70–75) and 80 wide (80–85). Palps about 35 long and wide, with distinct lateral notches. Palpalae l”G about 30 long, dF and dG subequal, 21–22 long, each with 8–9 tines, l”G 1.3 times longer than dF. Setae vF about 60 long. Subcapitulum ventrally with 1–2 pairs of small membranous projections. Peritremal branch about 40 long. Idiosoma 220 long (220–245). Dorsal shield 100 long (100–125) and 170 wide (170–180). Vulva with long lateral folds reaching posterior margin of idiosoma. All dorsal setae slightly serrate. Ventral setae and setae h2 smooth. Lengths of setae: vi, ve, si, and c2 90–110, se 120 (120–130), h2 40 (40–50). Genua I and II with 3 setae (d, l’, v’). Apical segment of legs III with 5 setae, apical segment of legs IV with 4 setae.

Type material. Holotype female ( OSAL 0077831) and 11 female paratypes (0077828–007 7 830, 0 0 7 7 832, 0 0 72833, 0 0 77835, 0 0 7 7 836, 0 0 79320, 0 0 83336, 0 0 82741, 0083343) from Spizella passerina (Bechstein) ( Passeriformes : Emberizidae ), USA: California, Mendocino Co., Hopland Field Station, 39°N, 123.08°W (USGS- GNIS).

Type deposition. OSAL.

Hosts and distribution. This species is known only from the type host Spizella passerina ( Emberizidae ) from North America (present paper; see Table 1 ). Moss (1979) misidentified this species as H. brevis .

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

Differential diagnosis. This new species is close to H. alaudinus . Females of both these species posses the same leg setation and similar lateral vulvar folds reaching the posterior margin of the idiosoma. They differ by the following features. In females of H. spizella sp. nov., palpalae l”G are 1.3 times longer than dF and setae h2 are 40–50 long. In females of H. alaudinus , palpalae l”G are 2 times as long as dF and setae h2 are 130–170 long.
