Abstract
Systematics of Marengo nitida Simon, 1900 is discussed and M. rattotensis new species is described. The female of M. nitida is described for the first time. M. rattotensis is diagnosed by the unique shape of its retrolateral tibial apophysis. M. nitida can be separated from other Marengo spp. by the rounded shape of its opisthosoma, and males by the characteristic retrolateral tibial apophysis. The genus Marengo now contains six species with most of them known only from Sri Lanka.References
