Body, including gnathosoma, 135–160 long and 185–200 wide. Gnathosomal length and width subequal, about 65. Palp about 30 long and 25 wide, without notches. Palpalae strongly different in shape ( Fig. 11 D): dF about 15 long, almost twice as long as dG (about 8 long) and about 4 times longer than l”G (about 4 long); dG 2–3 times wider than dF and l”G . Setae vF about 40 long, smooth. Subcapitulum ventrally as in female. Idiosoma about 160 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. Dorsal shield about 135 long and 165 wide; with anterior margin widely concave, narrowed in posterior part (about 40 wide), with straight posterior margin.

Idiosoma ventrally without scales or verrucosities, striated only anterior to setal bases 1a . Coxal fields I and II smooth. Leg I and II setation as in female. Solenidia ω 1 I and ω 1 II 9–10 long, narrow straight and conical, with rounded apex. Apical segment of leg III with 5 setae; preapical segment with 2 setae. Leg IV with 1 segment bearing 5 setae. Type material . Holotype female ( OSAL 0079988), 10 female and 3 male paratypes ( OSAL 0 0 77500, 0 0 77501, 0079976–00779980, 0 0 79983, 0 0 79986, 0 0 79987, 0079989–0079991, 0083599) from Calidris minutilla (Vieillot) ( Charadriiformes : Scolopacidae ), USA : Kansas, Douglas Co., Lawrence, 38.97°N , 95.24°W ( GNIS- USGS ), 11 May 1962 , coll. A.B. Amerson. Type deposition . Holotype and most of paratypes in OSAL , 1 female paratype each in UMMZ and ZISP . Etymology . The specific epithet is derived from the generic name of the host and is a noun in apposition. Hosts and distribution . Calidris minutilla ( Charadriiformes : Scolopacidae ) from USA (Kansas) (present paper). Differential diagnosis . Among species of the group capellae the new species is closest to Harpyrhynchoides capellae ( Fritsch, 1954 ) ( Fig. 11 H, I) and H. charadrius sp. nov . In females of these species, palpalae dF and dG are subequal in width and setae vi are present. These species differ from each other by the following character states. In females of H. calidris sp. nov . , palpalae dF are almost twice as long as dG (vs. subequal in H. capellae ); setae h2 are about 20 long, approximately 2.5 times longer than h1 (vs. h2 70 long, about 4 times longer than h1 ); in males, distance g2–g2 is approximately 1.6 times longer than g3–g3 (vs. g3–g3 about 3 times longer than g2– g2 ). It differs from females of H. charadrius by the shorter palpalae, dF 15–17 long, dG and l”G 6–8 long (vs. dF 30–32 long, dG 20–22, and l”G 12–14 long in H. charadrius ), subequal lengths of dG and l”G (vs. dG 1.7 times longer than l”G ) and by the partially striated ventral surface of the idiosoma (vs. idiosoma almost completely striated).
