Etymology. The specific name honours the Archbishop Dom Helvécio Gomes de Oliveira for his efforts to preserve the Rio Doce area that culminated with the creation of the Vale do Rio Doce State Park in 1944.

Diagnosis. Females of Scytodes domhelvecio n.sp. resemble those of S. caratinga n.sp. by the ridged positioning ridges (Figs. 57, 60) and by the round spermathecae on short stalks adjacent to hyaline pockets (Figs. 58, 61). They are distinguished by the larger, rounded hyaline pockets, medially touching each other and by the small, slightly rounded, lateral sclerotized area (Fig. 61).
