In alcohol, well-coloured specimens under low magnification pale to light brown in body colour, somewhat darker posteriorly on prozonites. Antennae long ( Fig. 69 pen), about 2.5X a socket diameter apart. Paranota wide, R = 1.6 ( Fig. 70 pen), anterior “shoulders” projecting forward, posterior corners not turned up. Legs long, moderately robust, tarsus slightly longer than femur, tibia with slight ventral distal swelling ( Fig. 71 pen). Telopodite ( Figs 60 , 61 ) almost reaching leg 5 when retracted. Solenomere arising at just under half the telopodite height, directed posterodistally at c. 45° to telopodite axis, twisted slightly helically, the tip bending distally, terminating with no subapical projection at half the prefemoral process height. Tibiotarsus unusually wide at base, initially parallel to solenomere but curving posterolaterally, then mesally, then distally; somewhat shorter than solenomere and terminating proximal to solenomere tip. Femoral process arising just proximal to solenomere origin, blade-like, forked at about one-quarter its length and not pressed close to prefemoral process, the two branches apically pointed and about equal in size; anterior branch curved anteriorly, then distally, approaching prefemoral process apically; posterior branch arcuate, concave anteriorly, bent more strongly anteriorly near tip; the two branches terminating at the level of solenomere tip. Prefemoral process at origin about two-thirds as wide as telopodite base, sharply narrowing at about one-third its length, the distal two-thirds gradually curving posteriorly, the tip mesolaterally flattened and not armed with teeth. Uncus large, arising laterally at level of solenomere tip, flattened posterobasally, the outer edge slightly crenulate. Distribution and habitat. Known from wet eucalypt forest to 250 m elevation on Forestier and Tasman Peninsulas in south-east Tasmania ( Fig. 72 ). L. peninsulensis appears to be uncommon and may have a total range of less than 200 km 2 . Etymology . Latin peninsula + - ensis , adjective, referring to the Forestier and Tasman Peninsulas.
