Tczew province. Brody Pomorskie settlement. Forest community of substitution on the habitat of acidophilous oak forest (<i>CalamagrostioQuercetum</i>), with addition of firs and pines. Herbaceous layer with <i>Viola riviniana, Mycetis muralis, Rubus saxatilis,</i> also <i>Entodon schreberi, Impatiens parviflora, Deschampsia flexuosa, Vaccinium myrtilius, V. vitisidea, Viola canina, Senecio silvaticum</i> and <i>Oxalis acetosella</i>.</p> <p>Sampled material: litter, soil under of fir, fir needles and sod.</p> <p>Second locality (“ JUDO 4 A...G”): North Poland. Tczew Province. Brody Pomorskie settlement. Pine forest (Domination of <i>Pinus silvestris</i>, also <i>Betula verrucosa, Frangula alnus, Sorbus aucuparia</i> and <i>Juniperus communis</i>). Undergrowt: <i>Vaccinium myrtilius, V. vitisidea, Deschampsia flexuosa, Melampyrum pratense, Convallaria maialis, Trientalis europaea, Polygonatum odoratum, Dryopteris spinulosa, Dicranum scoparium</i> and <i>Pleurozium</i> (= <i>Entodon</i>) <i>schreberi</i>.</p> <p>Sampled material: litter, soil and pine needles.</p> <p>Third locality (“ JUDO 9 A...G”) as in <i>E. formosus</i> sp. n. (see above).</p> <p> <i>Specimens</i>. Three females in slides 2 G / P 4, 2 G / P 5 and 2 G / P 7 (03 Jul. 2000). Female in slide 4 B / P 7 (31 Aug. 1999). Two females in slide 9 F / P 4 (02 May 2000). Female and deutonymph in slide 9 B / P 17 (31 Aug. 1999). Deutonymph in slide 2 G / P 10 (03 Jul. 2000). All specimens are kept in DAM.</p> <p> <i>Remarks</i>. One of the smaller species of genus <i>Eustigmaeus</i>, which belongs to “ <i>pectinata</i> ” group. The holotype derives from soil from California (USA), and it was formerly determined as <i>Ledermuelleria plumifer</i> (Halbert, 1923) by Summers and Price (1961). Both species are very similar and probably occur in Europe and in North America thus, some of the earlier data (before 1965) of <i>E. plumifer</i> might have been concerned in fact <i>E. myrtea</i>.</p> <p>Both closely related species have short, but very strongly plumose dorsal setae, rich ornamentation on all the surface of the idiosoma, similar size and total view. However, ornament of <i>E. myrtea</i> is in form of equally shaped cells and “craters”. Besides, it differs from <i>E. plumifer</i> by substantially longer distance between setae <i>a</i>, and by the presence of two setae on trochanter III instead of only single one in <i>E. plumifer</i>.</p> </body> </html>
