Description

Description. Male / female approximate measurements: length 16 / 16 mm, ring 12 paranota width 1.8 / 1.8 mm. Male as for T. armatum in live colour and most non-gonopod details, but long-preserved specimens completely decoloured, overall widths tergite 6> 5> 4> 3> (2, head)> collum, ring 12 paranota 1.4 × as wide as prozonite. Ring 6 sternite as for T. armatum, but with very short, thin sternal tab by leg 6, not bearing setae. Gonopod telopodite (Fig. 21) similar to that of T. armatum (see Fig. 7 A), but process 1 simply acute (but see Remarks) rather than Y-shaped; process 2 undivided, curving medially, apically expanded and flattened with dentate margin; distal margin of laminate process not extended posteriorly, instead curving smoothly to posterior extension, the latter shorter and straighter than in T. armatum; solenomere divided into distal branch with bifid tip carrying prostatic groove, and basal branch directed posteriorly but curving distally, with pointed tip; process 3 an anteroposteriorly flattened, quadrate tab, the margin free distally apart from central attachment; process 4 as in T. armatum; laterally with group of 5 – 6 setae, rather than three. Female with posterior margin of epigynum raised in centre as irregularly edged triangle. Figure 2 |. Tasmaniosoma orientale sp. n.
