Sampled material: litter, soil and pine needles. Third locality (“JUDO 9 A...­G”) ­ as in E. formosus sp. n. (see above). Specimens . Three females in slides 2G / P­4, 2G / P­5 and 2G / P­7 ( 03 Jul. 2000 ). Female in slide 4B / P­7 ( 31 Aug. 1999 ). Two females in slide 9F / P­4 ( 02 May 2000 ). Female and deutonymph in slide 9B / P­17 ( 31 Aug. 1999 ). Deutonymph in slide 2G / P­ 10 ( 03 Jul. 2000 ). All specimens are kept in DAM. Remarks . One of the smaller species of genus Eustigmaeus , which belongs to “ pectinata ” group. The holotype derives from soil from California ( USA ), and it was formerly determined as Ledermuelleria plumifer ( 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 E. plumifer might have been concerned in fact E. myrtea . 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 E. myrtea is in form of equally shaped cells and “craters”. Besides, it differs from E. plumifer by substantially longer distance between setae a , and by the presence of two setae on trochanter III ­ instead of only single one in E. plumifer .
