Per the 2015 revision on the genus, these two species are almost visually identical. They have the same color as well as the same range. Males can be distinguished through dissection, females can be distinguished by looking at the macrosetae on the metatibia: in fenestella, this hair is short and curved, in sayi it is long and curved.
