Diagnosis
Libitioides sayi differs from the other species of Libitioides by the following characters: short legs (femur IV shorter than or equal than DS length), small rounded tubercles in area III (instead of spines), small coda. Frequently without any spots in DS, chevron and omega stripe may be present (frequently fragmented). Ribs, backbone and lateral clouds never present. General color of body and appendages mustard yellow with a pair of much darker spots on scutal area III.
