Taxonomical note
Roewer (1943)[3] placed Discocyrtus serrifemur in the Pachylinae based on the observation of pigmentation on posterior part of dorsal scutum, which he assumed erroneously to be the scutal area IV. Both sexes of type series of Discocyrtus serrifemur are identical to Geraeocormobius sylvarum. In general, females of Gonyleptinae do not show conspicuous diagnostic characters, which are mainly seen in male tegumentary ornamentation. Both male and female specimens of Geraeocormobius sylvarum preserved in 70% alcohol present a general black coloration with olive or yellowish lateral marks on the dorsal scutum, with white pedipalps. Geraeocormobius sylvarum could be confused with Geraeocormobius rohri (Mello-Leitão) and Geraeocormobius salebrosus (Roewer) because of its relatively larger body size, presence of large rounded tubercles on the scutal area III, general black coloration and geographical occurrence. However, Geraeocormobius sylvarum can be distinguished from them by the white pedipalps.
