Male genitalia. Pygofer broadened subapically. Appendage of segment X slender directed posteriorly, in posterior view crossing over each other. Subgenital plate narrow, with several hair-like setae on dorsal and ventral margin ( Fig. 4 H). Connective with two arms broad, central lobe small. Style tooth on ventral margin, with a few setae on dorsal margin. Aedeagus dorsal margin straight with smaller angular process in lateral view; shaft slightly compressed subapically, lateral margin not smooth, broadened in middle and lower regions slightly concave in ventral view ( Figs. 4 F, G). Etymology. The specific epithet refers to the aedeagal shaft dorsal margin having a small angular process in lateral view. FIGURE 4. Busonia lactata sp. nov.
