Abstract

A number of characters were overlooked in the original description of Macrophthamus boscii Audouin in Animaux invertébr 1(4):77–98, 1826, therefore this species is redescribed from material collected close to the type locality and, as the type series is no longer extant, a Neotype is designated. M. sinuspersici sp. nov. is described from the Persian Gulf and distinguished from M. boscii in possessing a distinct stridulating ridge on the upper surface of the merus of the male cheliped (vs fully lacking in M. boscii) and by first male gonopod which has apical process inclined mesio-laterally, strongly emarginated (vs a remarkable plate-shaped apical process in M. boscii).
