Male pygofer with widespread microtrichia and several small rigid setae on inner surface of hind margin; dorsal appendage present, free from pygofer side; ventral appendage absent; phragma lobe with spine-like setae present on each side of aedeagus, attached to dorsal apodeme of aedeagus by ligaments (Fig. 51 ). Subgenital plate upturned apically with lateral margin basally expanded triangular shaped with 2-4 lateral macrosetae in an oblique row slightly basad of midlength; lateral margin with short spine-like setae. Style apex usually with 3 points, sometimes 2nd point absent. Aedeagus with shaft laterally compressed, usually with processes, gonopore apical on ventral surface; dorsal apodeme and preatrium present or absent.
