Diagnosis. Members of this genus can be distinguished from those of other broscine genera in the region by the following combination of character states: body size large, BL> 15.0 mm; head with one pair of supraorbital setae; vertex with very deep, sharply defined and impunctate cleft between tempora; gula with two deep transverse grooves on each side; maxillae with two setae on eustipes; mentum with one pair of setae; submentum with three pairs of setae; antennomere 3 with apical whorl of fixed setae only, antennomere 4 with pubescence on apical one-third; pronotum with basolateral setae present; elytra with parascutellar setae present; male pro- and mesotarsi with ventral pads of adhesive setae on tarsomeres 1 and 2.

Diversity and geographical distribution. This genus is represented by only three species (Schmidt et al. 2013): Eobroscus lutshniki (Roubal) , restricted to the northeastern China, the Russian Far East, and Japan; Eobroscus masumotoi Morita, 1990 , restricted to Taiwan; and Eobroscus bhutanensis , treated below.
