Mischonyx Bertkau, 1880  

Mischonyx   Bertkau, 1880: 106; Kury 2003: 132; (type species: Mischonyx squalidus   Bertkau, 1880, by monotypy).

Eugonyleptes   Roewer, 1913: 219; Kury 2003: 123; (type species: Gonyleptes scaber   Kirby, 1819, by monotypy). Syn. n.

Gonazula   Roewer, 1930: 417; Kury 2003: 126; (type species: Gonazula gibbosa   Roewer, 1930, by monotypy). Syn. n.

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.

Composition.

Mischonyx anomalus   ( Mello-Leitão, 1936); Mischonyx antiquus   ( Mello-Leitão, 1934); Mischonyx cuspidatus   (Roewer, 1913); Mischonyx fidelis   ( Mello-Leitão, 1931); Mischonyx insulanus   (Soares, 1972); Mischonyx intermedius   ( Mello-Leitão, 1935); Mischonyx kaisara   Vasconcelos, 2004; Mischonyx poeta   Vasconcelos, 2005; Mischonyx processigerus   (Soares & Soares, 1970); Mischonyx squalidus   Bertkau, 1880 and Mischonyx sulinus   (Soares & Soares, 1947).
