Bezděk, Jan, 2016, Identity of taxa proposed inClythra (Coleoptera: Chrysomelidae: Cryptocephalinae) by Carl Peter Forsberg (1821), Acta Entomologica Musei Nationalis Pragae 56 (2), pp. 769-784 : 772-773

Clytra (Clytra) duodecimmaculata duodecimmaculata (Fabricius, 1781)

( Figs 7–11 )

Cryptocephalus 10-maculatus Fabricius, 1775: 106 (original description, junior objective homonym).

Cryptocephalus 12-maculatus Fabricius, 1781: 139 (new substitute name for Cryptocephalus decemmaculatus Fabricius, 1775 nec Cryptocephalus decemmaculatus (Linnaeus, 1758)) .

Clythra gigas Forsberg, 1821a: 266 , 283 (original description), syn. nov.

Type localities. Cryptocephalus decemmaculatus : ‘Capite bonae spei’ [ South Africa, Cape of Good Hope; patria falsa]. Clytra gigas : not stated.

Type material examined. Cryptocephalus decemmaculatus : not examined. Photographs of the holotype were sent from BMNH (ex collection Banks): ‘Chr: 10-maculatus. [h] / Fab. Entom. p. [p] 106. n. 3. [w, h] // Type. [w, h]’.

Clytra gigas : HOLOTYPE: J, ‘ Uppsala Univ. Zool. Mus. / Thunbergsaml. nr. 8215 / Typsaml. nr. 1761 / Clythra gigas Forsberg 1821 [r, p] // gigas. / 26 [box label, w, h]’ ( UUZM).

Distribution. South China ( GRESSITT & KIMOTO 1961), SE Asia ( KIMOTO & GRESSITT 1981), Sumatra, Java ( LACORDAIRE 1848).

Comments. FORSBERG (1821a) did not mention the origin of his specimen. It is possible that the holotype was collected by Thunberg in Java during his two visits to the island in the years 1775 and 1777.

Clythra gigas disappeared from the entomological literature. It is mentioned neither in LA- CORDAIRE (1848) who treated or at least commented on all Forsbergʼs taxa, nor in all subsequent catalogues by GEMMINGER & HAROLD (1874), JACOBY & CLAVAREAU (1906) and CLAVAREAU (1913). Comparison of the holotype of Clythra gigas with the photograph of the holotype of Clytra duodecimmaculata shows with reasonable certainty that they are conspecific and they are thus synonymized here.
