See Dunlop (2006 , pp. 172-173). Holotype . Probably originally in Danzig (= Gdańsk , Poland ), current whereabouts unknown (see also Dunlop 2006 ), from Baltic amber ( Palaeogene , Eocene ); precise locality unclear. Additional material. MB .A. 1662 (series 15/10, provisionally labelled “Gyantinae cf. Amilenus ” but not in fact referable to this genus; see above), probably from the site of the Goitsche open-cast Mine near Bitterfeld , Sachsen-Anhalt , Germany ; Palaeogene (Oligocene: Chattian). Description . MB.A. 1656 ( Figs 30 , 33 ) is an almost complete specimen of a fairly large harvestman in dorsal view. Body length: 2.1 mm ; width of prosoma and opisthosoma 1.3 mm . Carapace procurved anteriorly, with clear division into promeso- and metapeltidium, and centrally located ocular tubercle. Length of ocularium 0.225 mm , width 0.275 mm , distance from ocular tubercle to front of prosoma 0.25 mm . Opisthosoma covered by scutum parvum bearing in places slightly granular ornament; posterior region and any segmentation here obscure. Body covered with small black dots and a subcuticular, silvery pigment. Chelicerae equivocal. Pedipalps short and pediform, but details lacking. Legs relatively complete, at least proximally, elongate and slender. Leg 1 femur length 1.83 mm , patella, 0.24. Leg 2 only known from incomplete femora. Leg 3 complete with podomere lengths (in mm) of femur, 1.79; patella, 0.45; tibia, 1.52; metatarsus, 1.86, tarsus, 3.20. Tarsus divided into 24 individual elements, becoming shorter distally, and ending in a single claw (apotele). Leg 4 only known from incomplete femora. Remarks . Leiobunum longipes Menge, 1854 is present in both Baltic and Bitterfeld amber. Apparently quite common in Baltic amber ( Staręga 2002 ), this fossil is fairly large compared to the other Bitterfeld finds. Nevertheless, it is probably still only a juvenile, although we see nothing which differentiates it from the species known from Baltic amber.
