Etymology.The species name is a noun in apposition taken from the typelocality.
Diagnosis.The male of Stemmops carauari new speciesresembles that of S. bicolorO. Pickard-Cambridge, 1894(see Levi 1955, figs. 17, 18) by the embolus not coiled, and by the shape of embolus base and theridiid tegular apophysis ( Fig. 4), but differ by the embolus short with trajectory of the embolus that loops far from the tegulum edge ( Fig. 4), in S. bicolorembolus long, partly covering cymbium margin in ventral view, and by the shape of the apex of conductor ( Fig. 4), wider in S. bicolor(see Levi 1955, fig. 18).
