Comparative notes. Morphostenophanes papillatus is distinguished from congeners by the rows of strongly inflated tubercles on the elytra. It is also distinguishable by its extremely convex body and nearly straight pro- and mesotibiae. Alhough M. papillatus has exaggerated elytral tubercles different from other congeners, other character states (cephalic impressions, elytra widest behind middle, with encircled and merely interrupted segments of elytral striae, impressions on sternites III and IV) undoubtedly place it within the aenescens -group. Similar bronze body color suggest possible close relationship to M. luoxiaoshanus and M. curvitibialis .

Comments. Until now, all known specimens of this species were from Dalou Mountain, except one male examined by Gao & Ren (2009), which is from Fanjing Mountain, a part of Wuling Mountains. This specimen has less convex elytral tubercles, and narrower pronotum, which is different from those from Dalou Mountains. Therefore it is considered here as an uncertain identification. More specimens from Wuling Mountains are required for a reliable identification.
