Diagnosis: Medial branch of gonopod telopodite nearly uniform in width in medial or lateral view, with most distal point marked by small, rounded projection; anterior edge of ring 7 aperture adjoining anterior edge of prozonite; metatergite sculpture well-defined.

Description: Jeekel (1983) gives a very detailed description of the G. cineraceus   holotype, and the following notes and accompanying illustrations are given here only for the sake of consistency.

Male/female approximate measurements: length 18/ 19 mm, midbody prozonite diameter 1.4/ 1.5 mm, midbody width across paranota 2.4/ 2.5 mm. In alcohol, well-coloured specimens light greyish-brown. Antennal sockets separated by ca. 2X a socket diameter. Collum about as wide as head, D-shaped, slightly narrower than tergite 2. Raised areas on metatergites low but distinct. Gonopod aperture about one-half width of prozonite, ovoid, longer than wide, anterior edge adjoining anterior edge of prozonite, lateral edge raised posteriorly.

Gonopod telopodite ( Fig. 9) with very low base, somewhat expanded laterally and medially near junction with gonocoxa; long setae on posterolateral surface to level of branching at between one-quarter and one-third telopodite height. Solenomere massive at base, somewhat swollen posteriorly and medially, abruptly tapering at about half telopodite height, the distal portion bending posterolaterally before abruptly turning distally at 'elbow' and curving slightly medially, near the tip narrowing and bending slightly anteriorly. Medial branch Cshaped from base (concave posteriorly) and much narrower than solenomere at base, slightly flattened mediolaterally, with a small, basally directed projection on lateral surface just distal to solenomere 'elbow'; at top of 'C', at about half the height of distal portion of solenomere, bending posterobasally and slightly laterally, with a small, rounded projection on anterior (distal) surface at bend; terminating at level of solenomere 'elbow' in mediolaterally flattened, slightly expanded portion, truncated basally.

Female slightly larger than male, legs not swollen. Genital aperture with posterior margin not significantly raised. Cyphopods not examined.

Distribution: In forest from near sea level to at least 1200 m over ca. 25000 km 2 in New South Wales and Victoria ( Fig. 12). Found under logs at the type locality, in rotting wood at the Tallaganda State Forest site and in leaf litter at the Dyer Creek site.

Remarks: This species varies a little in size over its large geographic range, but is otherwise very consistent in body characters and gonopod details.
