Diagnosis.

Mischonyx resembles Currala Roewer, 1927 and Schenkelibunus Strand, 1932, which are gonyleptine of relatively smaller size (about 5 mm of dorsal scutum length). Mischonyx can 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–III with a paramedian pair of tubercles, those on I–II elliptical 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), Mischonyx is phylogenetically close to Hernandariinae . It is probable that due to the Roewerian classification, some species which should be in Mischonyx is placed elsewhere in Gonyleptinae . Therefore, a comprehensive revision of the subfamily is needed.
