Etymology. The specific name honors the collector of the type specimen, the arachnologist Diana Silva Dávila, in recognition of her efforts in studying the Peruvian spider fauna.

Diagnosis. Architis dianasilvae sp. nov. shares with A. cymatilis the shape of the CD, which are encapsulated in large, sausage-shaped sclerotised cases ( Figs 3D View FIGURES 3 , 8F View FIGURES 8 ), but can be distinguished by a wide transverse keel in the anterior half of the epigynum, covering the copulatory openings ( Fig. 8E View FIGURES 8 ).
