Anthidium luizae Urban, 2001
This species is only known from the female holotype. It can be confused with small forms of A. rubripes by the body color (black with largely ferruginous legs and incomplete bands on T1–T4), absence of tibial carina, absence of stout hairs on the outer surface of hind basitarsus and black sternal scopa. It can be distinguished by the clypeus with thinner clypeal margin, projected as a flat rim as seen in profile and T6, which is not basally elevated, with less projected, narrower depressed apical rim (1/3 of distal margin) and more pointed distal margin. Additionally, the yellow band of T5 is usually medially broken in A. rubripes and complete in A. luizae.
This species is only known from Ayacucho, Perú, a locality at high altitudes (~3400 m) in the western side of the Andes.
