I therefore consider it useful to provide a further unpublished record of this species, together with the first photos of this taxon (Figs 1, 2; Leica M205 C stereomicroscope).
Material examined: GUYANA: Upper Demerara-Berbice (region), camp on the Demerara River, 5°11’N 58°37’O (WGS84), October 1931, expedition by Nello Beccari [Babooncamp / Campo I sul / Demerara.X.31 // Guiana britannica / Sped. N. Beccari], 1 macropterous female .
Discussion: The above specimen is preserved in the collections of the Natural History Museum of the University of Florence (Zoological Section “La Specola”—MZUF), and was collected during Nello Beccari’s (son of the great naturalist and explorer Odoardo Beccari) expedition to British Guiana (cf. Beccari 1943), a country today known as the independent nation of Guyana.
This new locality adds a further distribution point to the scant and scattered records of this very rare taxon. It is possible that, like members of Heterocleptinae, this species also has terrestrial or semiterrestrial habits (cf. Schuh & Slater 1995) and thus might have been overlooked during research concerning aquatic insects.
