Dolibaina, Diego Rodrigo, Dias, Fernando Maia Silva, Mielke, Olaf Hermann Hendrik & Casagrande, Mirna Martins, 2015, Argyrogrammana Strand (Lepidoptera: Riodinidae) from Parque Nacional da Serra do Divisor, Acre, Brazil, with the description of four new species, Zootaxa 4028 (2), pp. 227-245 : 228

Argyrogrammana alstonii ( Smart, 1979)

( Figs 1–2 , 46 )

In 2011 a single male was collected at the hilltop while resting on the underside of a leaf about seven meters above the ground, around 18:00h. In 2014 three males were collected in a same day resting on the underside of leaves in the same tree from the record of 2011 around 16:00h.

This rare species was described from Trinidad ( Smart 1979) and further recorded in French Guiana ( Brévignon & Gallard 1995). The Brazilian specimens of A. alstonii have a dark orange color, like the French Guiana specimens; however, the light blue spot on the upperside of the forewing is larger than the French Guiana specimen ( Brévignon & Gallard 1995) and the holotype.
