Etymology. The specific name is a noun in apposition and refers to the type locality of the holotype.
Diagnosis. Males of Scytodes bonito n.sp. are distinguished from those of the remaining Neotropical Scytodes by the palp with a retrolateral, serrated, laminar projection (Figs. 64–65). The females are distinguished by the round spermathecae on long and curved stalks and fused hyaline pockets, with lateral sclerotized areas (Fig. 67).
