Male terminalia. Epandrium nearly entirely separated laterally at mid-dorsal portion, with ca 20 setae near posterior to ventral margins ( Figure 22A ). Surstylus with a few setae medially, finger-like process at postero-ventral corner, ca eight prensisetae on distal margin, and many setae on ventral margin and on outer mesal surface ( Figure 22B ). Anterior portion of hypandrium slightly broadened submedially ( Figure 22C, D ). Ejaculatory apodeme: apical plate with four pits on each lateral margin; stalk thick, long ( Figure 22E, F ).
