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 : 33

Taumacera coxalis ( Jacoby, 1899) , comb. nov.

( Fig. 96 )

Platyxantha coxalis Jacoby, 1899: 298 (original description)

Type material examined. SYNTYPES: 1 ♀, ‘Type / H. T. [white round label with red collar, p] // Dohrn / Sumatra / Soekaranda [w, p] // Jacoby Coll. / 1909-28a [w, p] // Platyxantha / coxalis Jac [b, h]’ ( BMNH); 1 ♀, ‘Soekaranda / Januar 1894 / Dohrn [w, p] // Jacoby Coll. / 1909-28a [w, p] // coxalis Jac [grey label, w]’ ( BMNH).

Comments. The species was unknown to subsequent specialists and was mentioned only in catalogues. WEISE (1924) listed it as Platyxantha (Haplotes) coxalis while WILCOX (1973) and KIMOTO (1990) classified it in the genus Polexima .

In the BMNH I found two female syntypes of Platyxantha coxalis which do not correspond with Jacobyʼs description as he mentioned only males ( JACOBY 1899). In my opinion, this discrepancy can be easily explained by the structure of antennae. Both females have slightly thickened apical antennomeres ( Fig. 96 ) which probably led Jacoby to treat them as males. Although the males are unknown to me I have no doubt that Platyxantha coxalis belongs to Taumacera based on habitus and the absence of tibial spurs.
