Lepidocyrtus cf. pallidus Reuter, 1890 Figs 3b, 9‒10., Tab 1 Material examined. Eight females on slides from compost in a private garden, Tjöme (Norway), position N59º09’ 0760” E10º25’55.57”, deposited at the UB (sample LP362), 6.iv.2014, Arne Fjellberg leg. Three females on slides from olive plants soil imported from Germany, Oslo (Norway, exact position unknown), deposited at the UB (sample LP379), 15.v.2014, Arne Fjellberg leg. Two specimens on slides (unknown sex) from vegetable cultures in Davis Station, Australian Antarctic Territory (Antarctica), position S68°34’36” E77°58’03”, deposited at the SAM (sample LP540). Remarks. All specimens have the same color pattern (Fig. 3b) and match the description previously done for L. pallidus (of the internal basal ungual teeth one tooth much larger than the other, labial chaetotaxy M1M2rEL1L2 , dorsal cephalic and body macrochaetae formula A0A2a A2S3Pa5 / 00/0101+2 , see Figs 4‒8) with the following differences: specimens from samples LP362 and LP540 with abd.IV chaeta F2 as smooth mesochaeta and located above chaeta E2 (Fig. 9). Specimens from sample LP379 with bilateral asymmetries on abd.IV dorsal chaetotaxy, with chaeta F2 as ciliated macrochaeta (and below E2 , Fig. 6) on one side, and as smooth mesochaeta (and above E2 ) on the other side of the body (Fig. 9). Also two specimens from sample LP362 and one specimen from sample LP379 bear (asymmetrically) on abd.IV one extra accessory chaeta of trichobotrium T2 located between chaetae m and a (chaeta m’ ) (Fig. 10). Discussion. Hüther (1971) described the species L. weidneri as closely related to L. pallidus . He pointed out that the main differences between the two species were the morphology of the internal basal ungual teeth (subequals in L. pallidus and one tooth much larger then the other in L. weidneri ), the labial chaetotaxy (with r chaeta strongly reduced or vestigial in L. pallidus , and R chaeta reduced and ciliated in L. weidneri ) and the dorsolateral abd.IV chaetotaxy (with chaeta F2 as ciliated ...
