Hadronotus argus (Kononova) comb. nov.
Gryon argus Kononova, 2005: 1353 (original description)
Comments.
From the original description, "The frontal indentation is superficial, not bordered by an arcuate keel, in transverse wrinkles, with a distinct longitudinal keel." The summary of the original publication, written in English, states that " Gryon argus is similar to G. coronatum, Kononova, but differs in abdomen proportions." Illustrations in the original description of G. coronotum depict a frontal depression that enables us to place that species in Hadronotus . It is on this basis and the presence of "transverse wrinkles" in the frontal depression that we make the generic transfer.
