site speculum also polished, with small, sharp, scattered punctures; 
lower 0.5 of mesopleuron anteriad likewise extensively polished and 
sparsely punctate; surface otherwise with gross but nearly parallel 
longitudinal wrinkles between speculum and anterior swelling, as 
well as with much gross wrinkling and foveolation in lower hind 
quadrant (where there are some intercalated smooth areas) and with 
strong wrinkles irregularly developed on peripheries of the smooth 
anterior-dorsal swelling. Lower metapleuron: with coarse and 
almost regular longitudinally oriented wrinkling. Hind coxa: dor-

areolet unusually large and high with intercubiti weakly convergent 
above; 2nd abscissa of radius 0.8 as long as 1st intercubitus; apical 
abscissa of cubitus originating far dorsad, the 2nd intercubitus only 
0.7 as long as ventro-posterior side of areolet; 2nd recurrent inserted
