Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Architis turvo sp. nov. is similar to A. tenuipes in the shape of epigynum and configuration of internal genitalia (see diagnosis of A. tenuipes ; also Fig. 9 View FIGURES 9 CD). These species differ by the wider median field and the presence of lateral posterior pockets in the epigynum of A. turvo sp. nov. ( Fig. 10B View FIGURES 10 ).
