Sekerka, Lukáš, 2014, Review of Imatidiini genera (Coleoptera: Chrysomelidae: Cassidinae), Acta Entomologica Musei Nationalis Pragae 54 (1), pp. 257-314 : 300

Pseudimatidium limbatum ( Baly, 1885) comb. nov.

Demotispa limbata Baly, 1885: 27 (type locality: ‘ Guatemala, Cubilguitz in Vera Paz’ ; ST! in BMNH!).

Homalispa limbifera Baly, 1885: 7 , syn. nov. (type locality: ‘ Guatemala, Cubilguitz , San Juan in Vera Paz’; ST! in BMNH!).

Remarks. BALY (1885) described H. limbifera and D. limbata from the same locality without any additional note. It is quite unusual because H. limbifera does not have prognathous and projecting mouthparts, like the other Homalispa species , and Baly was mostly quite careful about details, particularly in hispines. I have examined types of both species and found that they are conspeci¿c, H. limbifera representing just a teneral specimen of D. limbata . Therefore I synonymize them here and retain the name D. limbata as the valid one because its type specimen is fully sclerotized and perfectly preserved (following the First Reviser Principle, Article 24.2.1 of the Code ( ICZN 1999)).

Distribution. Guatemala: Alta Vera Paz ( BALY 1885).
