Anurida kyshyensis sp. nov. (Figs 1–11) Diagnosis. Blind whitish species of genus Anurida characterized by the presence of seven blunt sensilla on Ant.4 (S1– S4, S7–S9), oval PAO with about 20 lobes, mandibles with six teeth, maxilla with all three lamellae serrated, Th.2–3 with anterior position of p2-seta and few additional setae in lateral group, and 3+3 axial setae on tergum of Abd.4. Type material. Holotype (male) on slide, North-East of Russia, Chukchi Peninsula, vicinity of Lavrentiya (Lawrence) settlement, thick wrack mat on stony beach [N 65.5281°, W 170.9809°], 0 9 vii 2013, O. Makarova & A. Babenko leg. (MSPU). Paratypes (female and 3 juveniles), same data as holotype (MSPU). Description. Length without antennae 2.0–2.1 mm. General colour whitish with scarce granules of dark hypodermic pigment, especially conspicuous on dorsal side of head. Body shape typical of genus, rather slender and elongate, Abd.6 rounded, not truncate. Integument granulation more or less uniform and not especially coarse. Ocelli absent. PAO elliptical consisting of about 20 densely parked lobes (Fig. 1). Antennae clearly shorter than head, its shape typical of genus. Ant.4 with 3-lobed apical bulb, seven curved sensilla including additional one (S9) in lateral group, subapical ms and organite present (Fig. 10). AO on Ant.3 typical, outer sensilla widely separated, small ms present ventrally. Ant.1–2 with 7(8) and 12 setae, respectively. Labral formula as 4/3-5-2, lateral pair of prelabral setae widely separated. Labium with 11 setae on each side including three setae on its apical part also armed with two small sensillar papillae. Mandibles (Fig. 9) with three apical (third one set slightly out of line) and three larger basal teeth, most proximal one at least sometimes (seen in single individual) armed with additional thin teeth on outer margin. Maxillary capitulum with three strong teeth on main part and three clearly serrated lamellae, only lam.2 reaching well beyond tip of capitulum (Fig. 8). Most dorsal setae strong and ...
