This species, of which only one example is known, is said to be 
“the darkest of all the forms of Automolus, darker even than A. 
rubiginosus, and has much darker wings. On the underside it is 
more like the Guatemalan A. umbrinus, but the sides of the head and 
the flanks are much darker and the wings outwardly very differently 
coloured.”’
