(Figs. 24)
Description. FEMALE (holotype, Fig. 24). Body, including gnathosoma, 350 long and 315 wide. Gnathosoma 100 long and 105 wide. Palp 43 long and 60 wide, without lateral notches. Palpalae thickened (Fig. 24 C): dF 37 long, with 8–9 barbs, dG 31 long, with 7–8 pectinations, and l”G 21 long, with 6–7 barbs. Setae vF 63 long, smooth. Subcapitulum ventrally without membranous projections. Peritrematal branch 42 long. Idiosoma 250 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. All dorsal setae slightly serrate. Dorsal shield unornamented, with slightly concave posterior margin, 165 long and 215 wide.. Idiosoma ventrally without scales or verrucosities, distinctly striated except area bearing setae 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. Coxal fields I and II smooth. Vulvar pocket-like structure with moderately developed lateral longitudinal folds. Vulvar apodemes well developed. Ventral setae, setae h1 present. Lengths of setae: vi 116, ve 110, si 115, se 120, c2 150, h1 and h2 6–8. Solenidia ω 1 I and ω1 II 10–11 narrow straight and conical, with rounded apex. Empodium of tarsi I and II elongated, distinctly longer than respective tarsus. Genua I and II with 4 setae (d, l’, v’, v”), femur I with 4 setae (d and v triplicate), femur II with 3 setae (d and v duplicate), 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. Unknown.
Type material. Holotype female (UMMZ BMOC 81-0605-006) from Ixobrychus exilis (Gmelin) (Pelecaniformes: Ardeidae) (UMMZ 204377), USA: Michigan, Oakland Co., other data unknown, via Nankin Mills Nature Center.
Type deposition. Holotype in UMMZ.
Additional material. Three females (UMMZ) from Ixobrychus exilis (UMMZ 242829) [on skin in anterior ventral powder down], USA: Michigan, Washtenaw Co., Ann Arbor, University of Michigan campus, 42.2793409°-83.7386084° (from specimen catalog), 22 May 2012, coll. B.M. OConnor (falcon kill). All specimens in UMMZ.
Etymology. The specific epithet is derived from the generic name of the host and is a noun in apposition.
Hosts and distribution. Ixobrychus exilis (Pelecaniformes: Ardeidae) from USA (Michigan) (present paper).
Differential diagnosis. Among species of the group herodius this new species is closest to H. botaurus Bochkov and Galloway, 2013. In females of both these species, femur I has three adjoined ventral setae. These species differ from each other by the following character states. In females of H. ixobrychus sp. nov., the cuticular area bearing setae 3a and pocket-like vulvar structure is smooth (vs. striated in H. botaurus), setae h1 and h2 are short, shorter than 10 (vs. about 35 long), trochanters I and II bear a single seta each (vs. three setae), palpal seta dF is 1.8 times longer than l”G (vs. subequal).
