“…After carefully analyzing several digital pictures of the holotype (juvenile male), reviewing all of the literature concerning the issue, examining specimens of nearly all recognized species of the nigromaculatus group, and determining the locations visited by the specimen collector, we are able to point out the following: 1) Liolaemus nigromaculatus was collected between Puerto Viejo and Copiapó of the Atacama region in Chile, and not in Huasco 2) Liolaemus bisignatus is a nomen nudum, and populations attributed to Liolaemus bisignatus should be referred to as Liolaemus nigromaculatus. 3) There is agreement that Liolaemus copiapoensis is indistinguishable from populations currently referred to as Liolaemus bisignatus (= Liolaemus nigromaculatus), 4) Populations found in Huasco (currently considered the type locality of Liolaemus nigromaculatus) are very similar to those found in Caldera (currently considered Liolaemus bisignatus) and should be designated as Liolaemus nigromaculatus, and 5) Liolaemus oxycephalus and Liolaemus inconspicuus are not synonymous with Liolaemus nigromaculatus, although their true identities are difficult to determine. …”

“…It is based on the single-crystal X-ray diffraction of a natural sample from Jote West mine, Pampa Larga Mining District, Copiapo, Chile. The general structural feature of agardite-(Y) is characterized by infinite chains of edge-sharing CuO(5) square pyramids (site symmetry 1) extending down the c axis, connected in the ab plane by edge-sharing YO(9) polyhedra (site symmetry -6..) and corner-sharing AsO(4) tetra­hedra (site symmetry m..). …”
