Bezděk, Jan, 2019, Taumacera revisited, with new synonyms, new combinations and a revised catalogue of the species (Coleoptera: Chrysomelidae: Galerucinae), Acta Entomologica Musei Nationalis Pragae (Acta. Ent. Mus. Natl. Pragae) 59 (1), pp. 23-52 : 49

Metrioidea grandis ( Allard, 1889)

( Fig. 111 )

Atysa grandis Allard, 1889a : lxxix (original description)

Metrioidea borneensis Mohamedsaid, 1997c: 154 (original description)

Platyxantha robusta Jacoby, 1895b: 110 (original description), syn. nov.

Type material examined. Atysa grandis : SYNTYPES: 2 spec. unsexed, ‘Borneo [pink label, h] // Ex-Musaeo / E. Allard / 1899 [w, p]’ ( MNHN).

Platyxantha robusta : SYNTYPES: 1 ♂, ‘Type / H. T. [white round label with red collar, p] // N. Guinea [w, h] // Jacoby Coll. / 1909-28a [w, p] // Platyxantha / robusta Jac. / Type [b, h]’ ( BMNH); 1 spec. unsexed, ‘N. Guinea [w, h] // Jacoby Coll. / 1909-28a [w, p]’ ( BMNH). POSSIBLE SYNTYPE: 1 ♂, ‘Borneo [w, h] // 2nd Jacoby / Coll. [w, p] // robusta / Jac. [w, h] // Type. [p] / 18353 [r, h]’ ( MCZ).

Comments. Platyxantha robusta was completely overlooked by all subsequent authors and thus missing in all catalogues and publications. I have found two syntypes (male and an unsexed specimen) ( Fig. 111 ) in the BMNH. Platyxantha robusta is cospecific with Metrioidea grandis ( Allard, 1889) and the new synonymy is proposed. Another species, Metrioidea borneensis Mohamedsaid, 1997 was already synonymized with Atysa grandis by MOHAMEDSAID (2004). Platyxantha robusta was described from New Guinea which must be an error as Metrioidea grandis is known only from Borneo. This is supported also by the existence of another possible male syntype deposited in the MCZ with the locality label of “Borneo”.
