Fig. 3. Terminology for parts of the male style. A) Gray: style; black: style gap; B) Gray – main shaft; black – style′ apical extension (SAE) divided into 5 sections: B1 (tip), B2 (outer apical), B3 (inner apical), B4 (outer basal) and B5 (inner basal). Note that this naming scheme refers to the style itself rather than to the whole animal, thus, 'inner′ is the area 'inside′ the curved arc of the SAE, although in reference to the whole body it points laterally, rather than towards the aedeagus; C) SAE with bulge ofTS; D) SAE with bulge ofTT; E) SAE with bulge ofTB. In C–E the bulge is colored black while the rest of the SAE is colored gray, however, this distinction is for emphasis only, while in actual animals the black and gray parts are not distinguished; the SAE and the bulge it bears are a single structure.
