Figures

FIGURE 1. Drymopsalta wallumi sp. nov., Bokarina, near Kawana Waters, Sunshine Coast, southeast Queensland. A, lateral abdomen view; B, fore and hind wings; C, timbal (posterior margin at right, dorsal edge at top); D, left operculum. Scale bars 1 mm, except wings (3 mm). Terminology for selected wing veins and cells are shown (after Moulds 2012): 2 A, 3 A anal veins 2 and 3; a 1, a 5, a 8 apical cells 1, 5 and 8; ac 1, ac 2, ac 3 anal cells 1, 2 and 3; bc basal cell; cc costal cell; cuc cubital cell (FW); cuc 1, cuc 2 cubital cells 1 and 2, (HW); CuA cubitus anterior vein; M median vein; m medial crossvein; mc medial cell; r radial crossvein; RA radius anterior vein; rc radial cell; r-m radiomedial crossvein; RP radius posterior vein; u 1, u 3 ulnar cells 1 and 3. Terminology for the opercula is shown (after de Boer, A. J., 1999; note that the crest is described fully by the author as ‘ crest around distolateral corner of basal part of operculum’).
