Comments Given that Clythra macropus Thunberg, 1821 was a homonym of Clytra macropus Illiger, 1800 (now in Tituboea ), Lacordaire (1848) proposed the replacement name Clythra ( Plecomera ) thunbergii for Thunberg’s species. Lacordaire (1848) proposed the subgenus Plecomera for two species from the Cape : Clythra thunbergii Lacordaire, 1848 and Clythra quadraticollis Lacordaire, 1848 . Recently, Plecomera was treated at genus level by Medvedev (1989b , 1992a , 1993b , 2008 ) and Medvedev & Regalin (1997) without any other comment. The type species Clythra quadraticollis was designated by Medvedev & Regalin (1997) . Currently, Plecomera includes six species and one subspecies. However, the position of some species in Plecomera needs verification and the whole genus is in need of comprehensive revision. Fig. 9. Plecomera thunbergii thunbergii ( Lacordaire, 1848 ) . A–E .

Medvedev (2008) synonymized Plecomera thunbergii and P. quadraticollis arguing that the two taxa represent two extreme color variations of a single species, and he also described transitional forms.
