Description. Male c. 15 mm long, H = 1.4 mm. In alcohol, well-coloured specimens under low magnification very pale brown in body colour with two discrete, narrow, transverse bands of red-brown posteriorly on metatergites. Antenna slender ( Fig. 69 View Figure 69 dig). Paranota fairly wide, R = 1.5, with about 4 posterior marginal teeth ( Fig. 70 View Figure 70 dig), posterior corners not turned up. Legs robust, tarsus slightly longer than femur, tibia with prominent ventral distal swelling ( Fig. 71 View Figure 71 dig). Telopodite ( Figs 34 View Figure 34 , 35 View Figure 35 ) reaching leg 5 when retracted. Solenomere arising at half the telopodite height, directed posterodistally at a small angle to telopodite axis, terminating with small subapical projection at just over half the prefemoral process height. Tibiotarsus rod-like, directed posterodistally and between one-third and half as long as solenomere. Femoral process arising distal to solenomere origin at about one-third the prefemoral process height, blade-like, curving slightly anterolaterally and tapering to a blunt point, terminating at about the level of the prefemoral process tip. Prefemoral process about half as wide at origin as telopodite base, strongly tapering distally, curving posteriorly near tip and terminating in flattened, blunt point. Uncus prominent, arising at about half the prefemoral process height (just basal to solenomere tip).

Distribution and habitat. Known only from wet eucalypt forest at four sites within a c. 25 km 2 area near Mt Worth in West Gippsland ( Fig. 78 View Figure 78 ). At three of the four sites L. dignomontis co-occurs with L. gippslandicus , and at Yarragon South it co-occurs with L. johnsi .

Etymology. Latin dignus (“worthy”) + montis (“mountain”), noun in apposition. Named for Mt Worth, one of the known localities for this rare species.
