Description
Summary:Descriptions of Macrostylis antennamagna sp. n. and Macrostylis uniformis sp. n. are presented with notes on intraspecific variability and sexual dimorphism. Macrostylis uniformis sp. n. showes differences to Macrostylis antennamagna sp. n. in the length of the antenna 2, the shape of the pleotelson and length of uropods. The genus Desmostylis Brandt, 1992 (formerly including the two species Desmostylis obscurus Brandt, 1992 and Desmostylis gerdesi Brandt, 2002) is synonymised with the genus Macrostylis. Based on type material additional remarks and additions to the original descriptions are provided for both species. Results lead to following nomenclatorial changes: Macrostylis obscurus (Brandt, 1992), comb. n. and Macrostylis gerdesi (Brandt, 2002), comb. n. A setal nomenclature is proposed and the diagnosis for the family is revised.
