Previous record. Male holotype and 2 male, 2 female and 4 juvenile paratypes, near Silverband Falls, Grampians , Victoria [−37.1960 142.5250 ± 2 km], J.J.H. Szent-Ivany & M.L. Szent-Ivany, 6 May 1978, under bark of Eucalyptus sp. in forest, SAM ( Jeekel 2009, p. 31) .

Material examined. 1 male, 3 females, Broken Falls, Grampians , Victoria [−37.1110 142.4085 ±500 m], A. Burns, 30 Oct 1949, NMV K-13628 ; 1 male, 1 female, Grampians , Victoria [−37.2170 142.4350 ± 20 km], collector unknown, 10 Nov 1949, NMV K-13655 .

Description. Jeekel (2009) provides a detailed description of the types, but his notes on the anterior gonopod are brief. The Broken River male (fig. 1A) has sclerite a nearly erect, curving slightly posteriorly at apex, spatulate, concave posteriorly; small field of ca 12 short setae on anterolateral surface; medial margin slightly thickened subapically. Pseudoflagellum arising at ca 1/2 gonopod height on medial surface of sclerite a, thin, cylindrical, directed anterolaterally, tapering gradually to rounded tip basal to sclerite a tip; posterior surface of pseudoflagellum finely rugose. Sclerite b arising at ca 1/2 gonopod height, erect, reaching ca 5/6 gonopod height, directed slightly posteriorly, not expanded distally; distal margin oblique (lower posteriorly), slightly emarginate with sparse comb of short setae; posterior margin slightly sinuous. Sclerite c arising at ca 1/3–1/2 gonopod height, somewhat flattened mediolaterally and tapering to rounded tip, directed slightly laterally, strongly curving medially, reaching ca 2/3 gonopod height with 4–5 long well-spaced setae on medial surface at ca 1/3–1/2 sclerite c height.

Distribution. So far known only from the Grampians National Park in western Victoria (fig. 2).

Remarks. Jeekel (2009, p. 34) wrote that he had previously illustrated the anterior gonopod of A. solitaria in Jeekel (1985), where the species is referred to as “ Atelomastix spec. from South Australia [sic]”. Fig. 5 in Jeekel (1985; p. 108) shows a posterior view of the right anterior gonopod and is close to a mirror image of the posterior view of the left anterior gonopod in fig. 4 of the 2009 paper (reproduced here in modified form as fig. 1B). Neither of the two anterior gonopod illustrations in Jeekel (2009) is in side view, leaving the shapes of the gonopod sclerites a little unclear. The medial view in fig. 1A will allow easier comparison with Atelomastix anterior gonopods, as illustrated in side view by Attems (1911), Edward and Harvey (2010) and Mesibov (2017).
