description: 5. Schizocarpus klompeni sp. nov.
(Fig. 8)
Description. MALE (holotype). Body 380 long (370–385 in 10 paratypes) and 200 wide (200–210); body length/ width ratio 1.9:1. Idiosoma egg-shaped, strongly convex dorsally. Hysteronotal shield 110 long and 100 wide. Anterior margin of hysteronotal shield widely concave. Setae d1 situated in anterior angles of this shield, distance d1-d1 80. Setae e1 situated on hysteronotal shield distinctly anterior from its posterior margin, distance e1-e1 35. Setae h1 widely separated from each other, distance h1-h1 100. Setae f2 absent. Setae h3 situated ventro-laterally, distance h3-h3 80. Opisthosomal membranes moderately developed, about 25 long. Setae ps3 situated laterally, anterior to transverse level of adanal suckers. Adanal shields comma-shaped, with distinctly sclerotized external and weakly sclerotized internal borders and not punctated central areas. Minimal distance between these shields 20. Setae ad1 represented by alveoli, situated between or on inner margins of adanal shields, at same transverse level as adanal suckers. Distance between adanal sucker and seta ad1 subequal to diameter of adanal suckers or 1.3 times longer. Adanal suckers situated in anterior half of adanal shields, 15 in diameter, with dentate corolla (type E), without external sclerotized ring around. Setae ps1 on short peduncles about as wide as they long, situated between adanal shields near their inner margin, significantly postero-mesal to adanal suckers. Adanal setae ad2 represented only by alveoli, situated at posterior angles of adanal shields, at same transverse level as setae ps1. Ventral anal sclerite distinct. Lengths of some setae: h1 15, h2 160, h3 35, ps3 60, ps2 105. Tarsus III 28 long, 15 wide; tarsus IV 15 long, 18 wide.
Type material. Holotype male (ZIN T-Chir-20) and 20 male paratypes (ZIN AVB- 2011-0504-015, #1-20) from Castor fiber belorussicus [beaver #2], POLAND: Podlaskie Voivodeship, Suwałki County, near Wiżajny village, 54°21'50''N, 22°52'6''E, 17 April 2003, coll. A. Labrzycka; 12 male paratypes (ZIN AVB- 2011-0504-016, #1- 12), same data, 18 April 2003 [beaver #3]; 4 male paratypes (ZIN AVB- 2011-0504-017, #1-4), same data [beaver #5]; 2 male paratypes (ZIN AVB- 2011-0504-018, #1, 2), same data [beaver #6].
Type depositions. Holotype and most part of paratypes—in ZISP, 4 paratypes—in AMU, 2 paratypes in UMICH.
Microhabitat. Posterior legs, few specimens on neck dorsally.
Distribution. Type locality only.
Etymology. The species is dedicated to the well known acarologist Dr. Hans Klompen (Ohio State University, Columbus, USA).
Differential diagnosis. This new species is close to S. heatherae sp. nov. In both species, the idiosoma is eggshaped, the corolla of the adanal suckers is dentate, setae ps3 are situated laterally and setae f2 are absent. These species differ from each other by the following characters. In S. klompeni sp. nov., setae e1 are located on the hysteronotal shield, the adanal shields are comma-shaped and elongated, setae ad1 are represented only by alveoli and located at the same transverse level as the adanal suckers, setae ps1 are pedunculate and situated distinctly far from each other, setae ad2 are present, and tarsi IV are wider than long. In S. heatherae sp. nov., setae e1 are located off the hysteronotal shield, the adanal shields are roughly rounded in outline, setae ad1 are with short filiform bodies and are located distinctly posterior to the adanal suckers, setae ps1 are non-pedunculate and situated close to each other on a common sclerite, setae ad2 are absent, and tarsi IV are longer than wide.
