Clements split Vermiculated Screech Owl into three species [[#References|[1]]]. However, at least one other authority [[#References|[2]]] further splits one subspecies (''M. g. vermiculatus'') whilst reusing the name Vermiculated Screech Owl to indicate the resulting species:

''Otus vermiculatus''<br />

*[[Middle American Screech Owl]] - ''Megascops guatemalae'' (Includes ''M. g. vermiculatus'')

Some authors consider this a monotypic species without subspecies, others refer to a species Choco Screech Owl (''Megascops centralis'') Hekstra, 1982, which has previously been considered a subspecies of Vermiculated Screech Owl.

Gill and Donsker recognize every group as full species (although with different names: Middle American Screech Owl, Vermiculated Screech Owl, Choco Screech Owl, Roraima Screech Owl and Yungas Screech Owl (which is not even accepted as subspecies by Clements.). Dickinson has relumped the complex and accepts only 9 subspecies (''hastatus'', ''cassini'', ''fuscus'', ''thompsoni'', ''guatemalae'', ''dacrysistactus'', ''vermiculatus'', ''roraimae'' and ''napensis''). centralis is considered by some as a synonym of ''vermiculatus'' and therefore not a valid subspecies<sup>[[#References|[2]]]</sup>.
