Approximate length of palpalae ( Fig. 64 C): dF 23, dG 13 long, and l”G 11 long, thickened and pectinate. Setae vF about 20 long. Peritrematal branch about 45 long. Idiosoma 180 long. Dorsal shield about 125 long and 140 wide, with distinct punctation. Anterior margin of dorsal shield almost straight, posterior margin widely convex. Genital opening situated posterior to level of setal bases se. Aedeagus very short, 8 long. Distance g1–g1 about 15 long, g2–g2 about 7 long. Median part of idiosomal venter without striations. Setae vi and si about 12 long, se about 20 long, all smooth. Legs I and II with 4 articulated segments. Setation of legs I and II as in female. Solenidia as in Fig. 64 E, F.

Type material. Holotype female ( UMMZ BMOC 09-0408-001, #1), 2 female and 2 male paratypes ( UMMZ BMOC 09-0408-001, #2–5) [1 female and 1 male paratypes crushed] from Charadrius vociferus Linnaeus ( UMMZ 242081) ( Charadriiformes : Charadriidae ) [in skin of neck], USA: Michigan, Washtenaw Co., Ann Arbor, UM campus, 42.2793409°N, 83.7386084°W, 8 April 2009, coll. J. Hinshaw (falcon kill).

Type deposition. Holotype and most paratypes in UMMZ, 1 damaged female paratype in ZISP.

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

Hosts and distribution. Charadrius vociferus ( Charadriiformes : Charadriidae ) from USA (Michigan) (present paper).

Differential diagnosis. In Perharpyrhynchus charadrius sp. nov., the femur and genu of legs I and II are fused to each other (anterior legs are four-segmented) as in Perharpyrhynchus elseyornis Bochkov and Klompen, 2014 , P. jacana Fain, 1972 , and P. recurvirostra Fain, 1976 . Females of P. charadrius sp. nov. differ from these species by the presence of seta v on trochanter II and setae h1.
