Harpypalpoides sylvia sp. nov.

( Figs. 14 , 16 A)

Description. FEMALE (holotype, Fig. 14 ). Body 200 long and 190 wide. Gnathosoma 60 long. Palp femur-genu 28 long and 25 wide. Lengths of palpalae: dF 30, dG 15, l”G 6. Idiosoma 150 long, its striated cuticle dorsally covered by microscales. Propodonotal shield 135 long and 145 wide. Posterior part of propodonotal shield without ornamentation. Distinct U-shaped striae immediately anterior to setae ag present. Setae f1, f2, h1, and h2 and most of dorsal idiosomal setae distinctly serrate, except smooth e1. Setae h2 situated distinctly posterior to level of setal bases h1. Lengths of idiosomal setae: vi and ve about 60, si and d1 about 70, c2 55, e1 22 from one site and 50 from other site, e2 70, f1 65, f2 54, h1 55, and h2 50. Femur I with 3 setae (d, v’, and v” present), femur II with 2 setae (v’, and v” present). Setae dF I, dTr III, dTr IV, distinctly serrate, vTr III, vTr IV, vF III, and vF IV smooth. Setae vTr III and vTr IV about 2 times longer than setae vF III and vF IV, respectively.

MALE (1 paratype, Fig. 16 A). Body190 long and 165 wide. Gnathosoma 45 long. Palp femur-genu 30 long and 27 wide. Lengths of palpalae: dF 22, dG 6, l”G 15. Idiosoma 150 long, its striated cuticle dorsally covered by microscales. Propodonotal shield 120 long and 110 wide. Setae vi situated posterior to ve, distance between levels of setal bases vi and ve 6. Distance vi– vi 25, ve–ve 40. Setae si, d1, and e2 smooth, c2, f1, h1, and h2 serrate. Distance between levels of setal bases e1 and g1 15, between g1 and g2 20. Lengths of idiosomal setae: si 25, d1 23, c2 33, e2 20, f1 38, h1 45, and h2 40. Genital opening situated at level of setal bases d1. Leg setation as in female.

Type material. Female holotype ( OSAL 0082874) and 4 male paratypes ( OSAL 0082868, 0082875–0082877) [only 0082877 in good condition] from Sylvia atricapilla (Linnaeus) ( Sylviidae ), THE NETHERLANDS: Noord- Holland, Amsterdam, 52.37°N 4.89°E (GEOnet), 9 October 1976, coll. F.S. Lukoschus.

Holotype deposition. OSAL.

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

Differential diagnosis. This species is closely related to H. sitta sp. nov. In both these species, the dorsoidiosomal striae bear microscales, in females, setae e2 are serrate. H. sylvia sp. nov. differs from H. sitta sp. nov. by the following features. In females of H. sylvia sp. nov., setae e1 are smooth, setae vF III and vF IV are smooth and about twice as shorter than vTr III and vTr IV, respectively; in males, setae vi are situated distinctly posterior to ve, the genital opening is situated at the level of setal bases d1, and the distances between levels of setal bases e1–g2 and g1–g2 are subequal. In females of H. sitta sp. nov., setae e1 are serrate, setae vF III and vF IV are distinctly serrate and only slightly shorter or subequal to vTr III and vTr IV, respectively; in males, setae vi are situated almost at the same transverse level as ve, the genital opening is situated posterior to the level of setal bases d1, and the distance between levels of setal bases e1–g2 is almost twice the distance between setal bases g1–g2.
