- <p><b>Genus <i>Amblypalpus</i> Mitrofanov & Strunkova, 1978</b></p><p><b>Type species:</b> <i>Amblypalpus narsikulovi</i> Mitrofanov & Strunkova, 1978</p><p><b>Diagnosis (adult female)</b></p><p>Palps three-segmented; palp tarsus usually with 1 terminal phanere, or with highly reduced second phanere (<i>narsikulovi</i>). Anterior margin of prodorsum with distinct median forked projection forming a notch, sometimes flanked by lateral projections (<i>masakii</i>, <i>thomissus</i>); dorsal opisthosoma with 7–8 pairs of setae (<i>c3</i>, <i>d1</i>, <i>d3</i>, <i>e1</i>, <i>e3</i>, <i>f3</i>, <i>h1</i> present; <i>c2</i>, <i>d2</i>, <i>e2</i>, <i>f2</i>, <i>h2</i> absent; <i>c1</i> present, or absent in <i>masakii</i>); dorsal setae variable: fine, short (<i>masakii</i>, <i>narsikulovi</i>) or heteromorphic (<i>thomissus</i> with <i>sc1</i>, <i>c1</i>, <i>e1</i> very long, lateral setae thickened). Ventral and genital plates merged together into ventro-genital region (<i>masakii</i>, <i>narsikulovi</i>), or genital plate developed (<i>thomissus</i>); 2 pairs of <i>ps</i> setae (not known for <i>masakii</i>); anal plate membranous with <i>ps2–3</i> inserted longitudinally (<i>narsikulovi</i>, <i>thomissus</i>), or unknown (<i>masakii</i>); setae <i>4a</i> elongate fine (<i>masakii</i>, <i>narsikulovi</i>), or short (<i>thomissus</i>); supernumerary coxal setae <i>4a2</i> present (<i>narsikulovi</i>) or absent (<i>masakii</i>, <i>thomissus</i>), supernumerary coxal setae <i>3a2</i> absent. Trochanter setal formula 1-1-2-1 or unknown (<i>thomissus</i>). Femora formula 4-4-2-2 or 4-4-2-1; femur III seta <i>d</i> present, femur IV seta <i>d</i> present or absent (<i>masakii</i>). Genua formula 3-3-1-0 or 3-3-0-0; genua III with l seta present (<i>narsikulovi</i>) or absent (<i>masakii</i>, <i>thomissus</i>). Tibiae with five setae (<i>lʹʹ</i> present). Femora I–IV, genua I–II, tibiae I–IV usually with seta <i>d</i> and <i>lʹʹ</i> acicular, smooth (<i>narsikulovi</i>, <i>masakii</i>) or unknown (<i>thomissus</i>). Ontogeny of leg setae unknown. Tarsal claws pad-like. Opisthonotal pores present (<i>masakii</i>, <i>narsikulovi</i>) or absent (<i>thomissus</i>).</p><p><b>Remarks.</b> We propose that <i>Amblypalpus</i> includes just three species, <i>A. narsikulovi</i> Mitrofanov & Strunkova (the type species), <i>A. masakii</i> (Ehara & Ueckermann), and <i>A. thomissus</i> (Meyer). The diagnosis of the genus has been modified to exclude the species <i>A. iraniensis</i> and <i>A. thymus</i>, which are here moved to <i>Ueckermannopalpus</i> <b>gen. nov.</b> The three species of <i>Amblypalpus</i> have opisthosomal setae <i>h2</i> absent (Table 1), and the dorsal opisthosoma bearing 7–8 pairs of setae (i.e., <i>c3</i>, <i>d1</i>, <i>d3</i>, <i>e1</i>, <i>e3</i>, <i>f3</i>, <i>h1</i> present; <i>c1</i> present or absent). The absence of setae <i>h2</i> is considered a synapomorphy of the tribe Obuloidini (Beard <i>et al.</i> 2022) and is also observed in the genera <i>Terminalichus</i> Anwarullah & Khan, 1973 and <i>Goodeniacarus</i>.</p>
