Treatment

Pseudimatidium bicoloricornis (Pic, 1926) comb. nov.

Demothispa bicoloricornis Pic, 1926a: 14 (original description).

Type locality. Original type locality ‘Guyane Fr.ʼ specified by DESCARPENTRIES & VILLIERS (1959) to French Guyana: Saint-Laurent-du-Maroni based on the label data of the holotype.

Type material examined. HOLOTYPE: glued, ‘ GUYANE FRANÇSE | St-Jean du Maroni | COLLECTION LE MOULT [w, p, cb] || coll Pic [w, hw by Pic, s] || type [y, hw by Pic, s] || TYPE [r, p, cb] || Museum Paris | Coll. M. Pic [b, p, cb] || bicoloricornis | n sp [w, hw by Pic, s]’ ( MNHN).

Remarks. When I was assembling the data for my previous paper on Imatidiini ( SEKERKA 2014) I tentatively placed this species to Windsorispa Sekerka, 2014 because PIC (1926a) compared it to W. latifrons ( Weise, 1910) and the type was on loan to another researcher. Last year I had opportunity to study the holotype and found that it in fact belongs to the genus Pseudimatidium Aslam, 1966 and is most similar to P. madoni (Pic, 1936) , which differs in stronger punctation of elytra and pronotum.

Distribution. French Guyana: Saint-Laurent-du-Maroni ( DESCARPENTRIES & VILLIERS 1959).
