on ventral apical third, with row of 9-11 short spine-like 
setae; apex with 1 short, spur-like ventral and anterodorsal

midlegs somewhat pale, flattened and expanded; tarsomere 
4 and apical third of tarsomere 3 of hindleg slightly laterally 
compressed ventrally; tarsomere 5 of each leg lacking

sctl; all veins lacking setulae; R 4 and R 5 distinctly divergent
