Figures

Figs. 1-2. Wing venation in Antarctoperlaria. Color-coding following Kukalová-Peck & Lawrence (2004): yellow for the Subcosta (Sc) system; blue for the Radius system (R); red for the Media system (M); green for the Cubitus (Cu) system; yellow for the Analis system (A). Abbreviations as follows: ScP, posterior Subcosta; RA, anterior Radius; M, Media; CuA, anterior cubitus; CuP, posterior cubitus; AA1, first anterior Analis; AA2, second anterior Analis; α, β, χ, and δ are labels newly proposed for the branches of AA2. 1. Austroperla cyrene (Newman, 1845) (Austroperlidae), drawing and photographs of fore- and hind wing. 2. Stenoperla prasina (Newman, 1845) (Eustheniidae), drawing and photographs of fore- and hind wing.

Figs. 14-17. Austroperla cyrene (Newmann, 1845) (Austroperlidae). Details of the arculus, all dorsal view. 14. Left forewing; the arrow indicates the arculus, usual morphology. 15. Right forewing, same individual as in 14; the left arrow indicates the base of the arculus, i.e. the first cross-vein between M and Cu(A), basal to the base of CuA (itself indicated by the right arrow). 16. Left forewing; the left arrow indicates a vestigial crossveins directed towards the arculus (itself indicated by the right arrow). 17. Right forewing, same individual as in 16; the left arrow indicates a vestigial cross-vein occurring basal to the arculus (itself indicated by the right arrow); the arculus is reticulated.
