Other material. 31 males from 21 unique localities in northern Tasmania, including Caroline Creek, Christmas Hill, Dalgarth Forest Reserve, Dasher R., Don Reserve , Dulverton, Dysodile Hills, East Gawler R., Gog Range, Kelcey Tier, Latrobe, Lobster Rivulet, Long Hill, Marine Creek , Mersey R., Nook, Staggs Hill, Stella Glen, Warners Sugarloaf and Winter Brook .
Diagnosis. Gonopod with no femoral process or tibiotarsus; telopodite in posterior view with broadly notched tip, i.e. with 2 well-separated terminal teeth.
Description. Males c. 17–20 mm long and c. 1.8–2.0 mm wide at midbody. Body in both sexes lightly mottled with brownishpink pigmentation. Gonopod telopodites slender, more or less straight, lightly joined for about middle third of their length, a few short, coarse setae near bases just inside aperture (fig. 8). Aperture more or less ovoid, long axis transverse, posterior margin not noticeably raised. Telopodite slightly sinuous in lateral view, curving first anteriorly, then distally, then anteriorly, anterioposteriorly flattened towards its end and bending slightly laterally, broadly notched at its terminus to form two subequal teeth. No evidence of femoral process or tibiotarsus. Solenomerite short, helical, tapering process arising at about three-quarters of length of telopodite on its posterior face. Prostatic groove running distally and posteriorly on mesal side of telopodite, then bending first laterally, then mesally on posterior telopodite surface before running distally to enter solenomerite on its mesal side.
Distribution. In rainforest and wet eucalypt forest over c. 2300 km 2 in north-central Tasmania (fig. 12), from sea level to c. 700 m. Syntopic with G. psi at various locations through its range.
Etymology. From Latin rusticus, rural, adjective. Much of the range of this species is now an intensively farmed landscape.
