Harpyrhynchoides modestus, Bochkov & Galloway 2013: 413 (misidentification).

Description. FEMALE (holotype, 4 paratypes, Figs. 40 ). Body, including gnathosoma, 300 long (300–335) and 275 wide (265–280). Gnathosoma about 110 long and 85 wide. Palp 50 long (48–51) and 41 wide (40–42), without lateral notches. Palpalae thickened, about 6 wide, slightly different in shape ( Fig. 40 C): dG 12–13 long, with 6–7 pectinations, dF 16–18 long and l”G 18–19 long. Setae vF about 50 long, smooth, situated on small tubercle. Subcapitulum ventrally without membranous projections. Peritrematal branch about 45 long. Idiosoma 215–235 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. All dorsal setae distinctly serrate. Dorsal shield unornamented, 175 long (165–180) and 175 wide (165–180) with strongly concave anterior margin and widely convex posterior margin. Idiosoma ventrally without scales or verrucosities, almost completely striated striated excluding area bearing setal bases 3a and pocket-like vulvar structure. 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 4 times longer than between setal bases 1a. Ventral setae h1 present. Distance h2–h2 about 3 times longer than h1–h1. Coxal fields I and II smooth. Vulvar pocket-like structure very large, not striated, without long lateral longitudinal folds; its posterior margin reaching level of setal bases h1 and almost straight. Vulvar apodemes well discernible. Lengths of setae: vi and ve 110–120, si 130–140, se and c2 about 150, h1 and h2 about 17. Solenidia ω 1 I and ω 1 II narrow conical, slightly curved, with pointed apex, about 12 and 16 long, respectively. Empodium of tarsi I and II not elongated, only slightly longer or subequal to respective tarsus. Genua I and II with 4 setae (d, l’, v’, 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 1 segment bearing 4 setae.

MALE. Unknown.

Type material. Holotype female ( ZISP AVB 13-0325-004, #1) and 4 female paratypes ( ZISP AVB 13-0325- 0 0 4, #2–5) from Columba livia (Gmelin) ( Columbiformes : Columbidae ) ( RODO /110/ CEN /04), CANADA: Manitoba, Winnipeg, 9 March 2004, coll. T.D. Galloway and D. Holder (field number SM-1233); 6 female paratypes ( ZISP AVB 13-0325-003, # 1–6) from same host and locality ( RODO /77/ CEN /04), 17 February 2004, coll. T.D. Galloway and D. Holder (field number SM-1232); 7 female paratypes ( ZISP AVB 13-0325-0 0 5, #1–7) from same host ( RODO /1988/ CEN /03) and locality, 27 November 2003, coll. T.D. Galloway and D. Holder (field number SM-1239).

Type deposition. Holotype and 3 paratypes in ZISP, 1 female paratype in UMMZ, 13 female paratypes in JBWM.

Additional material. Two females ( OSAL 0 0 83709, 0083710) from Columba livia , USA: Kansas, Douglas Co., Lawrence, 38.97°N 95.24°W (GNIS-USGS), 14 February 1962, coll. G. Singer. All specimens deposited in OSAL.

Etymology. The specific epithet is dedicated to the well-known Canadian parasitologist, Prof. T.D. Galloway (University of Manitoba).

Hosts and distribution. Columba livia ( Columbiformes : Columbidae ) from Canada ( Bochkov & Galloway 2013) and USA (Kansas) (present paper).

Differential diagnosis. Females of the new species (males unknown) differ from two other previously known species of the group modestus ( Harpyrhynchoides modestus ( Fain, 1976) and H. coxatus (Fain, 1972)) by the following features. In females of H. gallowayi sp. nov., the posterior margin of the pocket-like vulvar structure is without a median prolongation and not striated (vs. with prolongation and striated), setae h1 and h2 are subequal in length (vs. setae h1 much longer than h2), and genua I and II bear four setae each (seta v” present) (vs. three setae— v” absent).
