Comments

The collection of UUZM houses two male syntypes of Clythra cruciata , one in good condition, the second with head and pronotum broken and artificially stuck back in the wrong position. Both examined syntypes agree well with the species definition of Gyriodera cruciata used in subsequent publications ( Lacordaire 1848; Jacoby & Clavareau 1906; Medvedev 1989b).

Currently, the genus Gyriodera Lacordaire, 1848 includes ten species, but the position of G. capensis ( Lacordaire, 1848) is uncertain and it should probably be moved to the genus Smaragdina Chevrolat, 1836 . The genus was keyed by Medvedev (1989b). Clythra cruciata is the type species of Gyriodera designated by Lacordaire (1848).
