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.
