Material examined.

BRAZIL. Rio de Janeiro: Ilha Grande, male holotype (SMF 900); Macaé, 16 ♂ & 6 ♀ (MNRJ 4601). Santa Catarina: Serra Azul, male holotype (SMF 1328); Gaspar, 1 ♂ (MNRJ 11584).

Diagnosis.

Mischonyx cuspidatus resembles Mischonyx poeta and Mischonyx scaber (see diagnosis of Mischonyx scaber ). Mischonyx cuspidatus can be distinguished from them by the median high, acuminated tubercle on the free tergites I–III.

Taxonomical note.

The type locality of Gonazula gibbosa , Serra Azul (in the state of Santa Catarina), is an unknown toponym from where seven species are recorded (see Kury 2003). As some of these species were rediscovered in Serra dos Órgãos (in the state of Rio de Janeiro), we believe that the opilionids from Serra Azul were mislabeled, although Mischonyx cuspidatus is a synanthropic gonyleptid ( Mestre and Pinto-da-Rocha 2004) with one of the largest geographical distributions known among Neotropical harvestmen (see records in Kury 2003).
