Syn. n.  GonazulaRoewer, 1930: 417; Kury 2003: 126; (type species: Gonazula gibbosaRoewer, 1930, by monotypy). Syn. n.  Diagnosis.  Mischonyxresembles CurralaRoewer, 1927 and SchenkelibunusStrand, 1932, which are gonyleptine of relatively smaller size (about 5 mm of dorsal scutum length). Mischonyxcan be distinguished from those genera by the combination of the following characters: anterior border of the carapace with robust spines; frontal hump on anterior margin of carapace and ocularium with a pair of spines; scutal areas I-IIIwith a paramedian pair of tubercles, those on I-IIelliptical and widest pair on scutal area III; lateral margin of the dorsal scutum with large white tubercles (in specimens preserved in 70% ethanol) .  Taxonomical note. According DaSilva and Pinto-da-Rocha (2010), Mischonyxis phylogenetically close to Hernandariinae. It is probable that due to the Roewerian classification, some species which should be in Mischonyxis placed elsewhere in Gonyleptinae. Therefore, a comprehensive revision of the subfamily is needed.  Composition.  Mischonyx anomalus( Mello-Leitao, 1936); Mischonyx antiquus( Mello-Leitao, 1934); Mischonyx cuspidatus(Roewer, 1913); Mischonyx fidelis( Mello-Leitao, 1931); Mischonyx insulanus(Soares, 1972); Mischonyx intermedius( Mello-Leitao, 1935); Mischonyx kaisaraVasconcelos, 2004; Mischonyx poetaVasconcelos, 2005; Mischonyx processigerus(Soares & Soares, 1970); Mischonyx squalidusBertkau, 1880 and Mischonyx sulinus(Soares & Soares, 1947).
