Redescriptions of the Australian majid spider crabs Leptomithrax gaimardii (H. Milne Edwards) and Paramithrax barbicornis (Latreille)
Abstract
Paramithrax gaimardii H. Milne Edwards, 1834, is redescribed and figured from photographs of the holotype. It is regarded as a species of Leptomithrax Miers, 1876, conspecific with L. australiensis Miers, 1876, and L. spinulosus Haswell, 1880. Paramithrax barbicornis (Latreille, 1825) is also redescribed and figured and is considered synonymous with Gonatorhynchus tumidus Haswell, 1880, following Balss (1929). This species was designated as the type of the genus Paramithrax H. Milne Edwards, 1834, by Desmarest (1858) and the genus Gonatorhynchus Haswell, 1880, is consequently reduced to synonymy with Paramithrax.
