REMARKS: Rondani’s (1856: 58) key for the genus Gonirhynchus Rondani, 1856 lists Gonirhyncus dispar as its type species, but he did not provide a detailed description, number or sex of the specimens. He later ( Rondani 1857: 241) redescribed this nominal species in detail, providing specific characters for the male and female. Stuke (2017: 1147) reported one male and two females in the MZUF. We also found three syntypes in this study.
