From the original description of Cryptolabis convoluta Alexander, 1931 . “Venation: r-m before or close to the fork of Rs; m-cu nearly its own length beyond the fork of M” ( Fig. 15 View Figures 15–19 ). “Hypopygium: Basistyles short and stout. Dististyle fleshy, provided with long setae, those at the

apex more spinous, with one or two similar stout setae on the lateral face. Aedeagus elongate, convoluted, beyond the base directed cephalad, thence bent on itself and directed caudad, narrowed apically. Phallosomic structure massive, the posterior portion microscopically roughened, the caudal margin with a broad V-shaped notch” ( Figs 16, 18, 19 View Figures 15–19 ).

Discussion. Males of Ozeoura convoluta , O. hemmingseni and O. tasmanica share a massive square aedeagal guide which is bilobed in O. convoluta and O. hemmingseni only. Whereas the tropical O. hemmingseni has differentiated gonostyli, they are simple in the more southeastern species O. convoluta , O. tasmanica and O. tonnoiri , the only species with the aedeagal guide spine-like. The characters most useful for the identification of male O. convoluta are the massive bilobed aedeagal guide together with very bulky hairy simple gonostyli. Ozeoura convoluta , ranging from tropical northeastern Queensland to Victoria, is apparently the most widely distributed species of the genus.
