Supplementary description. Male.
Tergite 8: transverse, apical portion with a few small setae, apodemes strongly sclerotized, about twice as long as apical portion, diverging basally. Tergite 9: apical portion relative large, moderately long seta on apical margin; apodemes strongly sclerotized, about as long as apical portion, diverging basically. Sternite 9 small, broadly bilobed, apex with a few long setae, apodemes short, merging. Aedeagus complex, asymmetric, basal piece greatly reduced, trigonium relatively broad, weakly sinuate, apex pointed, one edge with well-developed setae; parameroids absent (possibly represented by irregular projections on anterior edge of basal piece). Tegmen well developed, parameres well developed, long, thin, robust, and connected at their bases by a narrow stirrup-like bridge which partially surrounds the penis, one side of bridge fused to penis (
Fig. 21
).
