Remarks. The male lectotype and female paralectotype of Medmassa laurenti share the same somatic and genitalic morphology as Mandaneta sudana ( Karsch, 1880) . This species can be recognised by the very broad carapace, as long as wide, distinctive abdominal chevron markings ( Figs 16, 18 ), and heavily spined ventral tibiae and metatarsi of the anterior legs. The male palpal tegulum is oval with a distally curved embolus and conductor, and fine retrolateral median apophysis ( Fig. 17 ), and the female epigyne has distinctive arched ridges and anteriorly projecting spermathecae ( Fig. 19 ). The specimens are undoubtedly conspecific and their synonymy is here proposed.
