The type specimens are provided with one printed red label: “ LECTOTYPUS , [or PARALECTOTYPUS , resp.] / Cryptocephalus / bioculatus / Thunberg, 1827 / J. Bezděk des., 2018”. Comments Thunberg’s collection consists of six syntypes of Cryptocephalus bioculatus , which include three different species. The two specimens (Nos. 9466 and 9580) that best fit the original description are conspecific with Monolepta bioculata . Another specimen (No. 9468) is Monolepta cruciata Guérin de Méneville, 1847 . The last three specimens (Nos. 9467, 15175 and 15501) are Monolepta signata ( Olivier, 1808 ) , which were evidently mislabelled, as M. signata is an Asiatic species and its occurrence in southern Africa is improbable. These specimens were probably collected in Java and Thunberg mistakenly mixed them with southern African specimens. Fig. 15. A–I . Monolepta bioculata ( Fabricius, 1781 ) . A–B .

Paralectotype of Cryptocephalus bioculatus Thunberg, 1827 , ♂, 4.0 mm, UUZM (actually Monolepta signata (Olivier, 1908)) . As the type series is composed of three different species, syntype No. 9466 is selected and here designated as the lectotype , and the identity of Cryptocephalus bioculatus Thunberg, 1827 is fixed to one specimen. Due to this act, Cryptocephalus bioculatus is proposed as a new synonym of Monolepta bioculata ( Fabricius, 1781 ) . Monolepta bioculata is the type species of the genus Monolepta , and was recently redescribed, including study of the type material, by Wagner (2007) .
