Smooth cuticle between peritrematal branches and transverse striations apunctate. All dorsal setae slightly serrate. Dorsal shield unornamented, 135 long (135–140) and 200 wide (190–215), anterior margin widely concave, posterior margin widely rounded slightly concave in median part. Idiosoma ventrally without scales or verrucosities, median part of idiosoma without striations. Setae 1a situated slightly anterior to level of setal bases 1c. Setae 3a situated slightly anterior to 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 2 times longer than h1–h1. Coxal fields I and II smooth. Vulvar pocket-like structure without long lateral longitudinal folds, situated slightly anterior to coxal fields III. Vulvar apodemes distinctly developed. Lengths of setae: vi 100 (95–105), ve 83 (80–90), si 115 (110–120), se 90 (88–95), c2 115 (110–120), h1 and h2 about 5. Solenidia ω 1 I and ω 1 II 9–10 long, 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’), femora I and II with 3 setae (d and duplicate v), trochanters I and II with 1 seta (v). Apical segment of leg III with 4 setae; preapical segment with 1 seta. Leg IV with 2 segments; preapical segment with 1 seta; apical segment with 3 setae.

MALE (2 paratypes, Fig.21 ). Body, including gnathosoma, 225–235 long and 190–200 wide. Gnathosomal length and width subequal, about 65. Palp about 35 long and 20 wide, without notches. Palpalae thickened, subequal in width ( Fig. 21 C): dF about 12 long, dG about 10 long, and l”G about 8 long. Setae vF about 50 long, smooth. Subcapitulum ventrally as in female. Idiosoma about 185 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. Dorsal shield about 135 long and 150 wide; with straight anterior margin and widely concave posterior margin. Aedeagus about 80 long, almost straight, situated anterior to genital opening. Genital opening situated in posterior third of dorsal shield. Genital arch about 25 long. Genital setae 2–3 long; setae g2 situated slightly closer to g3 than to g3. Distance g1–g1 about 22, g2–g2 about 12, and g3–g3 about 20. Setae vi serrate, broken (probably long), ve, si, se, and c2 slightly serrate, 80–90 long. Idiosoma ventrally without scales or verrucosities, fully striated. Coxal fields I and II smooth. Leg I and II setation as in female. Solenidion ω 1 I 8–9 long, slightly thicker than ω 1 II 7–8 long, narrow straight and conical, with rounded apex. Apical segment of leg III with 4 setae; preapical segment with 1 seta. Leg IV with 1 segment bearing 3 setae.

Type material. Holotype female ( UMMZ BMOC 89-0315-001, #1), 11 female and 2 male paratypes ( BMOC 89-0315-001, #2–14) from Bubulcus ibis (Linnaeus) ( Pelecaniformes : Ardeidae ), ( UMMZ 227901) [adults free in anterior ventral powder down, juveniles imbedded in skin latero-ventrally], USA: Florida, Orange Co., Orlando, Lake Adaire, 28.5666208°N, 81.2608791°W (from museum catalog), 11 March 1989, coll. M. Nemazi.

Type deposition. Holotype and most of paratypes in UMMZ, 2 female paratypes 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. Bubulcus ibis ( Pelecaniformes : Ardeidae ) from USA (Florida) (present paper).

Differential diagnosis. Among species of the group herodius the new species is very close to Harpyrhynchoides herodius (Boyd, 1968) . In females of these species, palpalae dG are thicker than l”G and setae v of femora I and II are duplicate. These species differ from each other by the following character states. In females of H. bubulcus sp. nov., the pocket-like vulvar structure is situated slightly anterior to coxal fields III (vs. at level of posterior margin of coxal fields III in H. herodius —based on the original description and material from Ardea cinerea ) and setae 3a are situated on smooth cuticle (vs. almost fully striated); in males, the aedeagus is situated anterior to the genital opening (vs. posterior to the genital opening).
