Comments. The holotype male is deposited in the Zoologische Staatsammlung, Munich (Bavarian State Collection of Zoology). Thirteen males and 10 females are deposited in MNRJ. We revalidate the status of B. tuberculata based on the habitus and male genitalia as described and illustrated in Roth (1970). We do not consider it a member of the genus Hormetica , nor synonymous with Brachycola sexnotata (Thunberg, 1826) . In Brachycolini the L2d is distinguishable from the L2vm by one membrane and the spines in the prepuce having diverse forms, which can be very long ( Phoetalia ), small ( Brachycola Saussure, 1864 ) or arising from one large sclerotinized region. Likewise, the two species of Brachycola ( B. sexnotata and B. tuberculata ) also are distinguishable also by the habitus and the genital structures: B. sexnotata possesses pronotal caudal margins shaped like a hexagon, while in B. tuberculata the pronotal margins are straight; on the tegmina B. sexnotata has seven dark spots, while B. tuberculata has five spots. Also, in B. sexnotata the genital median sclerite possesses a thin L2d with a membrane full of tiny spines arranged horizontally and the right phallomere is apically straight, while in B. tuberculata the right phallomere is not straight, and the genital median sclerite is darker and possesses small spines surrounding the membrane that involves L2d.
