Specimens examined . PERU : 2 specimens in the Gembloux collection ( FSAG ), labeled as paratypes ; also Madre de Dios : nr Puerto Maldonado , Posadas Amazonas , 12°48.115’S , 69°18.019’W , 609 ft. , 30.ix–3.x.2004 , C.R. Bartlett , 1M ( UDCC ) . Notes. The two specimens we have examined that Lallemand deposited as “ paratypes ” were not mentioned at all in the original description ( Lallemand, 1956 ), and therefore cannot be genuine paratypes . They are very similar to one another, though not identical. The forewing cells are larger in one, and the margin of the basal forewing markings is well-defined and strongly arcuate in this same specimen, and irregular and less arcuate in the other, though we assume that at least one of them is truly fluvialis , and both are Alphinoides . The other specimen from Peru that we have seen corresponds to the latter of these two “ paratypes ”, and some details do not match the description of fluvialis . Despite this confusion, this species, and Scaralis (A.) inbio , are closely related to each other, S. quadricolor , and S. spectabilis , and there may certainly be additional undescribed species. As in most other species, the vertex has at most very small dark markings in the posterolateral corners adjacent to the supraocular lobes, and the crossveins of the basal forewing are numerous and highly contrasting.
