Subgenital plates, triangular, narrowing to apex, inner margin nearly straight, outer margin slightly concave and with setae along lateral margin. Aedeagus usually slender and long, without dorsal projection at base; aedeagal shaft tubular, with pair of processes apically or subapically, or near base; gonopore at apex. Connective Y-shaped.
