Palp 43 long (43–50) and 35 wide (30–40), without lateral notches. Palpalae thickened and subequal in length ( Fig. 35 A): dF 21–23, with 7 pectinations, dG and l”G 19–20, with 8–9 and 6–8 pectinations, respectively. Setae vF about 50 long, smooth. Subcapitulum ventrally without membranous projections. Peritrematal branch about 40 long. Idiosoma 215–240 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. All dorsal setae slightly serrate. Dorsal shield 145 long (135–145) and 145 wide (145–150). This shield covered by fine longitudinal striations, converged in posterior quarter and with straight posterior margin. Idiosoma ventrally without scales or verrucosities, almost fully striated. Setae 1a situated slightly anterior to level of setal bases 1c. Setae 3a situated at level of coxal fields III. Distance between setal bases 3a about 2 times longer than between setal bases 1a. Coxal fields I and II with transverse fine striations. Vulvar pocket-like structure without long lateral longitudinal folds. Vulvar apodemes well developed. Ventral setae h1 present. Lengths of setae: vi 130 (115–130), ve 110 (100–110), si 115 (115–125), se 110 (110–120), c2 125 (120–130), h1 and h 2 15–20. Solenidia ω 1 I and ω1 II 10–11 long, narrow straight and conical, with rounded apex. Empodium of tarsi I and II not elongated, only slightly longer or subequal to respective tarsus. Genua I and II with 3 setae (d, l’, v’), femora I and II with 2 setae (d and v), trochanters I and II with 1 seta (v). Apical segment of leg III with 5 setae; preapical segment with 1 seta. Leg IV with 2 segments; preapical segment with 1 seta; apical segment with 3 setae.

MALE (2 paratypes, Figs. 34 , 35 D–G). Body, including gnathosoma, 210–215 long and 165–170 wide. Gnathosoma about 60 long and 65 wide. Palp about 30 long and 28 wide, without notches. Palpalae subequal in length with few barbs ( Fig. 35 D): dF about 19, dG, and l”G 16–17. Setae vF about 25 long, smooth. Subcapitulum ventrally as in female. Idiosoma about 175 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. Dorsal shield about 125 long and 115 wide. Aedeagus about 50 long, strongly curved, situated posterior to genital opening. Genital opening situated in posterior quarter of dorsal shield. Genital arch about 15 long. Genital setae microsetae, 2–3 long; setae g2 situated equidistant from g1 and g3. Distance g1–g1 about 18, g2–g2 about 12, and g3–g3 28. Setae vi, ve, si, se, and c2 slightly serrate, about 90 long. Idiosoma ventrally without scales or verrucosities, distinctly striated. Coxal fields I and II smooth. Leg I and II setation as in female.

Solenidion ω 1 I about 10 long, strongly thickened, about 4 wide in median part; solenidion ω 1 II about 12 long, straight and conical, with rounded apex. Apical segment of leg III with 5 setae; preapical segment with 1 seta. Leg IV with 3 setae.

Type material. Holotype female ( UMMZ BMOC 07-0503-005, #1), 6 female and 2 male paratypes ( UMMZ BMOC 07-0503-005, #2–8) from Zenaida macroura (Linnaeus) ( Columbiformes : Columbidae ) ( UMMZ 241227) [imbedded in skin of wings], USA: Michigan, Washtenaw Co., Ann Arbor, UM Campus, 42.2793409°N, 83.7386084°W (from specimen catalog), 3 May 2007, coll. B.M. OConnor (falcon kill); 3 females and 1 male ( BMOC 10-0510-001, #1–4) from same host ( UMMZ 242301) and locality, 10 May 2010, coll. B.M. OConnor.

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

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

Hosts and distribution. Zenaida macroura ( Columbiformes : Columbidae ) from USA (Michigan) (present paper).

Differential diagnosis. Among species of complex A the new species is closest to Harpyrhynchoides metropelia ( Fain, 1972) . In females of both these species, genua I and II have three setae each, femora I and II have two setae each, proximal segments of legs III and IV have a single seta each, distal segment of leg IV has three setae, and the idiosomal venter lacks scales or verrucosities and is almost fully striated. These species differ from each other by the following character states. In females of H. zenaida sp. nov., setae h1 and h2 are subequal (vs. h1 about seven times longer than h 2 in H. metropelia ), the posterior margin of the dorsal shield is straight (vs. widely convex); in males, setae g2 are situated equidistant from setae g1 and g3 (vs. setae g2 more three times closer to g1 than to g3), the aedeagus is strongly curved (vs. straight), solenidion ω 1 I is strongly thickened, at least twice thicker than solenidion ω 1 II (vs. solenidia ω 1 I and II subequal), and setae vi are about 90 long (vs. 42 long).
