Figure 2. Top, Brachoria species left male acropodites (with setae removed): (left) medial view and (right) magnified apical view. A–C, gonopod scanning electron micrographs, labelled with key anatomical features. A, 'bulky' gonopod from Brachoria splendida (SPC000171), scale bar = 1 mm; B, 'narrow' gonopod from Brachoria hendrixsoni (SPC000219), scale bar = 1 mm; C, acropodite from B. hendrixsoni, magnified view of cingulum and prostatic groove. D, Brachoria initialis gonopod diagram, colour-coded by region – dashed lines indicate junctions between (moving distally from the prefemur) the precingular region, postcingular region, and apex. Abbreviations: ap, acropodite; ax, acropodite apex; ca, cannula; cg, cingulum; cx, coxa; post-cg, postcingular region of acropodite; pre-cg, precingular region of acropodite; pf, prefemur; pp, prefemoral process; ps, prostatic groove. The gonopod comprises the acropodite, prefemur, and coxa.
