Males and females with head + 20 rings; adults 8-9 mm long; midbody metatergites typically with 3 transverse rows of 12 large tubercles; posterior portion of prozonite (Fig. 2B) with small disks, no microtubercles; ozopores not on porosteles; gonopod telopodite with two posterior bends, one at about midlength and one near tip, the more basal bend marked by strong anterior production of telopodite.


As for Prosopodesmus crater , differing in the following details:

Male/female lengths ca 8/9 mm, respectively. Ring 12 with maximum vertical diameter 0.8 mm; maximum width (including paranota) 1.2 mm and 1.7X prozonite width. Ring 2 slightly narrower than collum. 3 transverse rows of typically 12+12+12 tubercles on metatergites.

Gonocoxae (Fig. 3B) massive, strongly tapering anteroventrally and posteroventrally. Telopodite (Figs 3B, 5B) strongly produced anteriorly at about midlength, bending posteriorly there and again near tip. Hairpad mound medial on posterior surface midway between second bend in telopodite and tip. Thin, rounded tab on medial edge of telopodite just below level of hairpad; thin, rounded tabs on lateral edge at level of first bend and just distal to hairpad; narrow longitudinal ridge medially on posterior telopodite surface from near base to near first bend.


Rainforest in the mountains southwest from Tully and northwest from Ingham, Queensland, with a known north-south range of ca 25 km (Fig. 8).
