Rabidosa rabida - Look for the white 'spots' inside the posterior portion of the abdominal stripe.

Rabidosa santrita - Look for the horizontal lines through the posterior portion of the abdominal stripe.

Rabidosa punctulata - Venter of abdomen very pale brownish yellow (beige) with few-to-many scattered, variably-sized dark spots. Occasionally the venter is all dark brown or black.(2) Most confused with Rabidosa rabida and Rabidosa carrana.
