( Figs. 48 , 49 )

Description. FEMALE (holotype, 3 paratypes, Figs. 48 ). Body, including gnathosoma, 315 long (270–315) and 235 wide (200–235). Gnathosoma about 90 long and 100 wide. Palp 37 long (35–40) and 30 wide (29–35), without lateral notches. Palpalae thickened, different in shape ( Fig. 48 C): dG subequal in length to dF, about 19 long and 3 times thicker than other palpalae, with 11–12 pectinations, l”G about 22 long. Setae vF about 45 long, smooth. Subcapitulum ventrally without membranous projections. Peritrematal branch about 42 long. Idiosoma 250–265 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. All dorsal setae distinctly serrate. Setae ve situated posterior to level of setal bases vi. Dorsal shield unornamented, 165 long (155–165) and 160 wide (150–160) with almost straight anterior margin and concave posterior margin. Idiosoma ventrally not striated except posterior part posterior to vulvar apodemes; striations posterior to setae h2 with microspurs. Setae 1a situated 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. Ventral setae h1 present. Distance h1–h1 about 1.4 times longer than h2–h2. Coxal fields I and II with small membranous fold in posterior part. Vulvar pocket-like structure without lateral longitudinal folds. Vulvar apodemes weakly discernible. Lengths of setae: vi, ve, si, se, and c2 —all 50–65, h1 and h2 about 12. Solenidia ω 1 I and ω 1 II about 6 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 2 setae (v duplicate). Apical segment of leg III with 5 setae; preapical segment with 1 seta. Leg IV with 1 segment bearing 4 setae.

MALE (2 paratypes, Figs. 49 ). Body, including gnathosoma, 210–230 long and 165–180 wide. Gnathosoma about 65 long and 75 wide. Palp about 31 long and 27 wide, without notches. Palpalae strongly different in shape ( Fig. 49 C): dG about 16 long, almost twice as wide as other palpalae, dF and l”G about 22 long. 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 wide, with almost straight anterior margin and posterior margin widely rounded. Aedeagus about 65 long, almost straight, situated posterior to genital opening. Genital opening situated in anterior third of dorsal shield. Genital arch about 12 long. Genital setae about 3 long; setae g2 situated 2 times closer to g3 than to g1. Distance g1–g1 about 12, g2–g2 and g3–g3 about 6. Setae vi about 17 long, smooth; ve, si, se, and c2 —all serrate, 50–60 long. Idiosoma ventrally with microscales anterior to setal bases 1a, not striated excluding posterior part at level of coxal fields IV. Coxal fields I and II smooth. Leg I and II setation as in female. Solenidia ω 1 I and ω 1 II about 6 long, spur-like. Apical segment of leg III with 5 setae; preapical segment with 1 seta. Leg IV with 1 segment bearing 4 setae.

Type material. Holotype female ( OSAL 0082454), 3 female and 2 male paratypes ( OSAL 0 0 82439, 0 0 82441, 0 0 82451, 0083615) from Crotophaga ani Linnaeus ( Cuculiformes : Cuculidae ), SURINAME: Paramaribo, Weg naar Zee, 05.82°N 55.17°W (GEOnet), 17 September 1971, coll. F.S. Lukoschus & N.J.J. Kok.

Type deposition. Holotype and paratypes in OSAL.

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

Hosts and distribution. Crotophaga ani ( Cuculiformes : Cuculidae ) from Suriname (present paper).

Differential diagnosis. The new species differs from all other representatives of the genus, by the position of setae ve distinctly posterior to level of setal bases vi in females and by the position of the genital opening in the anterior third of the dorsal shield in males. Among species of complex B, it differs by duplicate setae v on trochanters I and II in both sexes.
