Material examined. New South Wales, Australia: AM C103630 (one shell measured, photographed), Dorrigo (30º23' S, 152º44' E), pre 1912, S.W. Jackson GoogleMaps ; AM C334357 (one specimen dissected, radula examined), WNW of Wauchope , Werrikimbe National Park, Mount Boss (31º12' S, 152º23' E), Aug. 1956, P. Rawlings, H. Cogger GoogleMaps .

Description. External morphology: Shell ( Figures 7H View FIGURE 7 , 8H View FIGURE 8 , 9H View FIGURE 9 ) reduced, 3.2 whorls, orange-brown; shape and sculpture as for genus. Animal (in ethanol) ( Figure 5D View FIGURE 5 ) grey with yellowish sole. Right mantle lap of moderate size, left mantle lap small, both rounded. Right mantle lobe of moderate size, median and left mantle lobes fused, small. Caudal horn small; caudal foss vertical slit in tail.

Mantle cavity and digestive system: As for genus.

Genital system ( Figures 12E View FIGURE 12 , 13E View FIGURE 13 ): As for genus. Free oviduct long; internal longitudinal pilasters absent. Penis short, wide; epiphallus enters penis through simple pore; penis internally smooth, eight longitudinal penis pilasters present. Penial sheath present, enclosing only base of penis. Epiphallus longer than penis, internally with wavy longitudinal pilasters.

Radula ( Figure 15J–L View FIGURE 15 ): As for genus. Radular formula (70.24.1.24.70) × 132 rows.

Range and habitat. Parmavitrina planilabris is found in rainforest, sclerophyll forest and scrub, and is most common from Taree to Dorrigo in northern New South Wales. Specimens recorded from further south, around Wyong and Ourimbah, probably represent the undescribed species noted above. The semislugs are ground dwelling and are usually found under logs or in leaf litter.

Remarks. Parmavitrina megastoma is found just to the north of the range of P. planilabris , being found from around Coffs Harbour to Grafton. The other known species, Parmavitrina sp. , is found further to the south than P. planilabris , around Wyong and Ourimbah.
