st
and 3
rd
interstriae slightly more strongly elevated on posterior half of disc and on declivity; 1
st
and 3
rd
interstriae each with a row of small, subcrenulate tuberculations throughout, others usually with smaller tuberculations near base; declivity convex, steep; odd-numbered interstriae distinctly elevated, 3 and 9 elevations join and then continue almost to 1
st
interstria; odd-numbered interstriae each with a few to many small tubercules, others unarmed; vestiture of moderately abundant, short, almost hair-like setae throughout elytra; body length:
