( Figs. 7 , 9 B)

Harpypalpus longipes, Moss 1979: 382 (misidentification)

Description. FEMALE (holotype, Fig. 7 ). Body 195 long (195–225 in 7 paratypes) and 175 wide (175–190). Gnathosoma about 55 long. Palp femur-genu about 30 long and 30 wide. Lengths of palpalae: dF about 23, dG 8–9, l”G about 15. Idiosoma about 190 long, its striated cuticle with indistinct microscales. Propodonotal shield about 100 long and 110 wide. Setae vi, ve, si, and d1 weakly serrate, e1 and e2 smooth. Setae se, c2, f1, f2, h1, and h2 distinctly serrate. Setae h1 situated almost at same level as setal bases f2; setae h2 situated distinctly posterior to level of setal bases f1. Lengths of idiosomal setae: vi, ve, si, se, d1, and c 2 25–30, e1 and e 2 26 –28, f1, f2, h1, and h 2 30–35. Setae 3a present. Setae dF I serrate, dTr III and dTr IV reaching respective tarsi, serrate; setae vF III and vF IV absent. All ventral setae of legs smooth.

MALE (6 paratypes, Fig. 9 B). Body 155–170 long and 150–160 wide. Gnathosoma 45–50 long. Palp femurgenu about 30 long. Lengths of palpalae: dF about 20, dG 8–9, l”G about 10. Idiosoma about 130 long, its striated cuticle with indistinct microscales. Propodonotal shield about 110 long and 115 wide. Setae vi situated posterior to ve, distance between levels of setal bases vi and ve 5–7. Distance vi–vi about 25, ve–ve about 50. Setae si, se, d1, and e2 smooth, c2, f1, h1, and h2 serrate. Distance between levels of setal bases e1–g2 and g1–g2 subequal, 8–10. Lengths of idiosomal setae: si 14–16, se about 25, d1 and e 2 10 –12, c2 about 25, f1, h1, and h2 about 25. Genital opening situated anterior to setal bases d1. Leg setation as in female.

Type material. Female holotype ( OSAL 0082535), 7 female and 6 male paratypes ( OSAL 0082536, 0082537, 0082891–0082900, 0082902) from Pyrrhula pyrrhula (Linnaeus) ( Fringillidae ), THE NETHERLANDS: Gelderland, Nijmegen, 51.8333°N 5.8667°E (GEOnet), 2 December 1968, coll. F.S. Lukoschus.

Holotype deposition. OSAL.

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

Differential diagnosis. This species is close to H. tiarae (only females known). In females of both species, setae vF III and vF IV are absent and setal bases h1 are situated almost at the level of setal bases f2. These species differ from each other by the following features. In H. pyrrhula sp. nov., the dorsal idiosomal striae are covered with indistinct microscales and setae vi and ve are 26–30 long, not extending close to the level of setal bases d1. In H. tiarae , the dorsal idiosomal striae are without microscales and setae vi and ve are 44–45 long, almost reaching the level of setal bases d1.
