General color brown with darker markings. Wings pale brown with darker veins ( Fig. 2d ). Male . Forewing length 18 mm . Tergum 9 bearing a small, raised mesal lobe and a sparse patch of sensilla basiconica; tergum 10 slightly notched on anteromesal margin and bearing a faint dark median line narrowly dividing large sensilla basiconica patch ( Fig. 2a ). Paraprocts broadly triangular, flattened but with strongly recurved, spinelike tips ( Figs. 2a, 2b ). Hammer small, oval and set near posterior margin of sternum 10 ( Fig. 2c ). Y-stem of aedeagal sclerite shorter than arms, laterally compressed and blunt apically; arms ca. 1.3 times as long as stem, strongly narrowed to a stiletto-type shape in apical half; lateral projections very prominent ( Fig. 2f ). Etymology . The species name refers to the prominent lateral projections of the aedeagal sclerites. Diagnosis . This species is distinguished from related congeners by the strongly projecting extensions present at the bases of the aedeagal arms. In addition, tergum 9 bears a slight, median dome sparsely covered with sensilla basiconica ( Fig. 2a ).
