Chimarra (Otarrha) usitatissima Flint, 1971

Widely distributed in the Amazon river basin (including Peru and Ecuador), also present in Surinam, Guyana, coastal watersheds of Venezuela, and south-eastern Brazil. The species was collected beside the Comté River near Cacao.

Examined material. FRENCH GUIANA, one male, 4°33’7.38’’N, 52°29’52.88’’W, 19 m a.s.l., 21.ix.2010, F.- M. Gibon & B. de Mérona leg. ( CBGP) .

Not surprisingly, these French Guianan species are already known from Surinam or Brazil. A considerable inventory work remains to be undertaken. Fourteen species of Chimarra are known from Surinam ( Holzenthal & Calor 2017), eight are known from the Brazilian State of Para ( Paprocki & França 2014), two of them are common to both lists.
