Comments.

Based on the comparison of S. spinicollis and B. sumatrensis, we found that there are no significant differences between the two species. For example, in both species, the body colour is predominantly pale reddish brown, the pronotum has a small, rounded, ochraceous pubescent patch on each side of the anterior margin, which is distinctly separated from the outer pubescent patch and the posterior large, rounded pubescent patch, and the elytra that are unevenly scattered with the yellowish brown pubescence. Therefore, we propose that B. sumatrensis Breuning, 1966 is a junior synonym of S. spinicollis Breuning & de Jong, 1941 .

As B. sumatrensis is the type species of Bulbolmotega, this genus becomes a junior synonym of the genus Spinosodus .
