Etymology. The specific name is a noun in apposition that refers to the type locality of the holotype.

Diagnosis. Males of Scytodes marlieria sp.n. are distinguished from those of the remaining Neotropical Scytodes by the very slender, slightly laminar distal region ( Figs. 49–50 ) with a prolateral sclerotized process ( Fig. 50–51 ).
