Trichocyphus Heller is a monotypic genus revised by Lanteri (1989). Its single species T. formosus only occurs in the high Andes of South America (Puna biogeographic province) and the coastal deserts of Chile and southern Perú.
Characters of the vestiture were studied in detail by Coscarón et al. (1991) and mouthparts, by Díaz et al. (1990a).

Based on color and distribution of the scaly vestiture Kuschel (1949) recognized three varieties of T. formosus herein treated as morphotypes: formosus from Chile and Perú; rubricollis from Argentina, Bolivia and Chile; and pulcher, from Chile. In Argentina occurs only the rubricollis morphotype, with reddish pronotum and elytra almost denuded of scales (only with erect setae).


Diplostephium meyenii Wedd., Senecio sp and Lepidophyllum sp (Asteraceae) (Kuschel 1949, 1950b), low shrubs typical of arid environments.

It is associated with vegetation of the Puna biogeographic province, between 3000- 4000 meters above sea level.
