Redescription.

Body relatively broad. Head retracted backwards, frons wider than long. Antennae shorter than body, with short setae beneath; antennal insertions flat, not obviously protruding upwards, widely separated from each other; scape short and stout, pedicel relatively long, antennomere 3 slightly longer than antennomere 4 or scape. Eyes slightly coarsely faceted, inner side deeply emarginate, lower lobe longer than broad, remarkably longer than gena. Pronotum transverse, with two transverse grooves on anterior and posterior margins, respectively, the second one on anterior margin strongly curved backwards at middle; each side provided a small but acute spine behind the middle, slightly directed backwards; disc uneven, with a large and blunt hump on each side. Elytra wider than pronotum, rounded apically; each elytron with a longitudinal blunt median ridge at base. Prosternal process narrow, lower than procoxae; mesosternal process shortly vertical anteriorly; metasternum normal. Legs moderately long, femur slightly clavate.

Comments.

Based on the comparison of the type species of Spinosodus and Bulbolmotega (images and original descriptions), we found no significant morphological differences between these genera. As a result, Bulbolmotega is considered a junior synonym of Spinosodus .
